ElevationLab ‘TagVault’ keeps your AirTag hidden in plain sight

https://photos5.appleinsider.com/gallery/41745-80948-wetbo-xl.jpg

ElevationLab will soon ship the the “TagVault,” a rugged, waterproof holder designed to keep your AirTag safe.

The TagVault is a two-piece AirTag holder that screws together with stainless Tox hardware, offering complete protection from bumps, scratches, and normal wear and tear. This makes it an attractive option for attaching to objects like keys and luggage.

Securing an AirTag inside will up the water-resistance of the AirTag to being completely waterproof. Should you drop your keys in a stream while hiking, for instance, it could offer more protection than a bare AirTag.

TagVault is designed to be nondescript, giving no indication that it holds an AirTag inside. This may dissuade someone from removing it and disposing of it. The manufacturer suggests clipping them on backpacks, luggage, purses, and more.

The TagVault is now available for preorder, priced at $12.95 for a single TagVault, or $29.95 for a set of three. ElevationLab will be shipping orders in June.

SIG Romeo2: The Hybrid MRDS

https://www.recoilweb.com/wp-content/uploads/2021/04/SIG_Romeo2_00.jpg

We first got eyes-on a concept of the Sig Romeo2 a couple years back and have been anticipating the release ever since. Originally slated for a 2020 release, hammering out the final details and a global pandemic pushed the official release until sometime in 2021. What we have in our hands is marked as an engineering sample, but SIG assures us it’s a good representation of what will be on the shelf.
With the Romeo2, SIG set out to make a true hybrid of a traditional open-emitter sight and a compact sealed reflex sight. Though sealed reflex sights are physically larger, they offer a number of advantages over an open-emitter reflex sight. First and most importantly, the emitter is sealed away from environmental fouling; stray lint or pocket sand can’t block an emitter unless you manage to pile up enough to block the entire window. They’re also easier to clean and can generally be made more durable. But the Sig Romeo2 goes both ways.

Straight from the box you get what appears to be a traditional open-emitter sight that we’ve come to expect from an MRDS. Digging further in you find a shield for the open configuration, a larger shield for sealed configuration, and a polycarbonate lens with an o-rig to make that seal actually happen.

Sig Romeo2
The shields cleverly cantilever from the front and are held in place by two very small fasteners that we’re sure we’ll lose if we blink too slow. Definitely going to recommend the use of appropriate thread locker (such as Loctite 222) for this one.

Also included is a clever multi-tool wrench with a flathead for windage/elevation adjustment, a small torx for the shield screws, and a T-10 bit in a 28in-lb torque limiter. SIG also took the extra step of lasering the proper torque settings on the optic body itself—bravo!
Sig Romeo2 rear sight
There’s an integral rear sight on the Romeo2 that corresponds to a suppressor-height front sight. There are horizontal lines to cut glare, and two perfect divots carved out if you wish to put a drop of paint in them. Brightness selection is performed via two push buttons on the left side. Access to the battery door does not require any special tools nor removal of the optic; a simple push on the recessed button pops open the battery tray.

Sig Romeo2 mounted
In what’s bound to be an upset to current small, sealed reflex sights, the SIG Romeo2 does not require any special footprint. The Romeo2 will fit all SIG Pro footprints, which translates to an awful lot of Leupold Delta Point Pro mounts too. The Picatinny mount we used for this build was for a DPP, as SIG didn’t yet have mounts in stock, and it worked just fine. Some mounts may have to be modified slightly.

It can be set to an auto-off if you so desire, and there’s even a magnetic-off option (with big-name duty holsters on the way).
Sig Romeo2 cover
These power-saving measures are just bonuses though, as the battery life is 25,000 hours on the medium setting (out of 12). It’s a touch lower than we’d use, and we’ll watch what happens real-world. But seeing as how the batteries are both plentiful and easy to swap, it’ll probably be just fine.

Sig Romeo2
There will be plenty that will run the Sig Romeo2 in a traditional style (that felt weird saying about MRDS’) with a pistol and sealed on a subgun. Or the reverse—you can do what you want, and that’s the entire point. If the battery life is as advertised and we don’t lose any screws, we daresay this may be the best red dot for those who can’t make up their minds or swings both ways.

MRDS: Micro Red Dot Sight Buyer’s Guide

https://www.recoilweb.com/wp-content/uploads/2021/04/MRDS-buyers-guide-cover.jpg

There was a time when even the very best micro red dot sight (MRDS) would only last a couple thousand rounds on a pistol before the violent reciprocation of the slide shook it to pieces. Incremental improvements over the years resulted in some extremely tough and durable sights, some with battery life better measured in years rather than hours. And just as quality red-dot sights for rifles were eventually produced for beer-money buyers, we’re now starting to see the same in the MRDS market.

We decided to focus on budget-friendly dots with a price ceiling of $300. Of course, actual street prices are normally considerably lower. This list is far from all-inclusive and new MRDS options are being released on a regular basis. However, due to the nature of foreign manufacturing, at least some of the “new” options may well be a rebranded variation of something you see here today.

TESTING

We used a modified AF 1951 ISO 12233 test chart to evaluate optics. Not only does this chart show resolution, it also provides distortion information including optical error, chromatic aberration, centering errors, and more. For an MRDS, we focus on three optical issues: magnification, displacement, and color cast.  

MRDS micro red dot buyer's guide diagram

Despite being advertised as 1x, sometimes an optic will slightly magnify or shrink the image seen through the glass. Displacement is the shifting of objects in view, usually vertically with an MRDS but sometimes horizontally. Color cast represents the accuracy of the color rendition of the view through the optic. This happens because special coatings are used to reflect the red (or green) reticle projection back to the shooter; they allow all light sans red to pass through the glass.

Some of these issues sound rather alarming, but odds are your favorite MRDS has some or all of these errors to some degree. Bear in mind that when you’re target-focused and shooting with both eyes open, these flaws are less important than they may seem at first. 

In terms of durability, only time will tell for many of them. Even an optic with the best reputation may fail, so training for a downed-optic is paramount if you’ll be carrying with one. Inexpensive dots can still have a place as a secondary sighting system or on a range or training gun. 

FEATURES

For each optic, we’ll explore listed features and use. Several different mounting footprints are seen across these pages. The current most-popular optical footprint milled into pistol slides is that of the Trijicon RMR, with the Leupold DeltaPoint Pro trailing behind. Other footprints that you’ll see are the RMS Shield (JPoint/DocOptic/FastFire) as well as the RMS-C (for subcompact guns). Those with plate-system guns such as the Glock MOS-series or the FN 509T are able to easily accommodate most optics, whereas others will have to seek out conversion plates or universal adapters if they don’t have a pistol with their mount in-hand. The RMS Shield footprint is gaining traction with subcompact pistols, with some manufacturers using it over the RMS-C when space is available. 


Atibal MRD V3

Dot Size: 3 MOA
Footprint: Shield
Battery Type: CR1632
Battery Life: Up to 05,000 hours
Weight (No Mount): 2.1 ounces

Atibal MRD v3 micro red dot sight

In CONCEALMENT Issue 19, we got our first look at a preproduction MRD V3. One of the changes you’ll see between the preproduction and full production is the inclusion of a rubberized cover around the optic window. Though we’re told it helps make the dot even more rugged, we’re sure the wave of cease-and-desist letters from Trijicon to many manufacturers last year may have something to do with it. 

Adjustment is performed with a small flathead. The clicks are both audible and tactile Each click corresponds to 1 MOA of adjustment. 

There are seven brightness settings and no auto-adjust, but it does feature a 12-hour auto-off. The window is one of the roomiest in this article. 

Color rendition is very good. There’s no change to magnification, but some slight vertical refraction is present. 

In terms of batteries, the CR1632 battery used by the MRD V3 isn’t as common as a CR2032, but still easy to find. It also lasts more than five years and is top-fill so it can be replaced without losing zero. 


Burris FastFire3

Dot Size: 3 or 8 MOA
Footprint: Shield
Battery Type: CR1632
Battery Life: Up To 5,000 hours
Weight (No Mount): 0.9 ounce

burris fastfire3 micro red dot sight

As you may have divined by the name, Burris has been continually improving and updating their MRDS offerings. Our example is well-used, having spent time on everything from a 22LR Ruger pistol to an offset mount on a scope to an airsoft training gun. 

Adjustment is performed with a small flathead. The 1 MOA clicks are just barely tactile, but you’ll never be able to feel them through gloves. 

There are four brightness settings, including an auto-adjust mode that uses a sensor on the front to determine the proper brightness. The dot is crisp at lower brightness settings but begins to bloom at the highest setting. 

Color rendition is slightly blue. There’s no errant magnification but there’s some vertical refraction present. 

The FF3 uses a CR1632 battery. Battery life is only 5,000 hours so we’re thankful that it can be changed without requiring a re-zero.


Bushnell RXS-250

Dot Size: 4 MOA
Footprint: Deltapoint Pro
Battery Type: CR2032
Battery Life: Up To 50,000 hours
Weight (No Mount): 1.5 ounces
Objective Lens Size: 24 x 17 mm
Dismount to Replace Battery? No, Top-Fill
URL: bushnell.com
MSRP: $250

bushnell rxs 250 mrds

First introduced in fall 2020, the RXS-250 packs a ton of quality into a street price just above $200. It has a ruggedized body without the cheap Chinese anodizing feel of many others on this list. We’ve seen one dropped several times on concrete that was no worse for wear, and we’re told it passes MIL-STD-810 drop testing while mounted on a loaded pistol.

The clicks are both audible and tactile, and each click corresponds to 1 MOA of adjustment. You need a small flathead to make adjustments.

There are 10 brightness settings and no auto-adjust. 

Color rendition is just ever-so-slightly blue but isn’t distracting. Magnification is 1x, but we see some vertical refraction. 

For batteries, no complaints here; not only does the RXS-250 use the common CR2032 battery, it can be replaced without removing the optic and has an anticipated battery life of more than five years. 


Crimson Trace CTS-1250

Dot Size: 3.25 MOA
Footprint: Shield
Battery Type: CR1632
Battery Life: TBD
Weight (No Mount): 1 ounce
Objective Lens Size: 27 x 17 mm

crimson trace CTS-1250 Micro red dot sight

Though they’re certainly still making lasers, Crimson Trace began dipping their toes into the optics game a couple short years ago. We began seeing their MRDS pop up as OEM options on other pistols (see our review of the XD-S Mod 2 OSP in RECOIL Issue 53), and now they’re enjoying a wider release. It’s so new that at the time of this writing, we don’t even have all of the details of this optic. You’ll note the lack of a hard battery life rating, though undoubtedly by the time of publication it’ll be available (and we’re told should be better measured in years and not hours). 

Adjustments are made with a small flathead. The clicks are both audible and tactile, and each click corresponds to 1MOA of travel. 

There are 10 brightness settings, including three that are NV-compatible. There’s no auto-adjust. 

Color rendition has just a kiss of blue. There’s a slight reduction in magnification and also some horizontal refraction. 

The CTS-1250 uses a CR1632 battery. The optic doesn’t have to be removed to swap the battery.


NC Star FlipDot M2

Dot Size: 3 MOA
Footprint: RMR
Battery Type: CR2032
Battery Life: ???
Weight (No Mount): 1 ounce
Objective Lens Size: 22 x 16 mm
Dismount to Replace Battery? Yes
URL: ncstar.com
MSRP: $100

Nustar flipdot m2

Yes, this is the cheap red dot with a neat flip-out action. This giant ball of fail is so bad even NC Star has discontinued it because of constant issues. It has since been replaced with the FlipDot Pro. What surprised us is that the NC Star FlipDot ships with several mounts, including a Glock dovetail adapter, Glock MOS plate, RMR spacer, and Picatinny mount. As the name implies, the dot can be flipped up by pressing a springform switch.

At this point, we’d normally talk about adjustment, but the lens itself loosened under recoil within a couple shots. Awesome.

Color rendition is blue but not terrible when viewed head-on. Surprisingly, there’s very little in terms of other optical errors. 

For batteries, the FlipDot uses a CR2032. The optic must be removed to re-zero, and no battery life was listed (which doesn’t seem to be a good sign). 

Leave this one for cheesy SyFy channel movies.

sig romeo zero

SIG Sauer has long since jumped into the optics game, and they developed the Romeo Zero with their P365 XL in mind (see CONCEALMENT Issue 15). The Romeo Zero is well-sized to ride on top of subcompact pistols as well as 1911s. Though the body is polymer, we’ve seen few complaints regarding durability from those using them every day. 

Adjustments are made with the included hex wrench, but there are no tactile clicks. The Romeo Zero ships optically centered, so it’s not too much of an ordeal.

A standout feature is the integral rear sight; the Romeo Zero will co-witness with standard sights. There are eight brightness settings and no auto-adjust, as well as an auto-off and shake awake. 

Color rendition strays into the blue spectrum. There’s an ever-so-slight reduction in magnification but no refraction.

For batteries, the Romeo Zero uses a CR1632. Though the sight does have to be removed to replace, with its battery life that shouldn’t be too much of an issue.

The SIG Romeo Zero is a set-it-and-forget-it optic. Give your batteries a swap every other year. Interestingly, the Romeo Zero is assembled in Oregon on an automated, robot-equipped production line rather than purely by hand. We toured SIG’s optics manufacturing facility last year and marveled at the robot overlords putting them together.

hex optics wasp mrds

You probably haven’t heard of Hex Optics before, but you’ve definitely heard of Springfield Armory. Springfield started Hex to not only have OEM options for their own pistol line, but to also sell them independently. Along with the launch of the micro-mini Wasp, another initial offering will be the Dragonfly, a duty or competition model with an RMR footprint. 

A hex wrench is included for adjustments. While there are no tactile or audible clicks, the Wasp ships with an external guide for zero adjustments, similar to the original Burris FastFire series. 

Like the SIG Romeo Zero, the Wasp has an integral rear sight for co-witnessing with standard-height front sights. The body is constructed of T6 6061 aluminum, and there’s no user-selectable brightness — auto-adjust is all you have, and the Wasp is always on. 

Color rendition is excellent. There’s a slight reduction in magnification and some horizontal refraction. 

The Hex Wasp uses the common CR2032 battery, the largest possible that’ll fit into this miniature sight body, and the optic must be removed to replace it. 


Swampfox Liberty

Dot Size: 3 MOA
Footprint: RMR
Battery Type: CR1632
Battery Life: ~9,000 hours, real use
Weight (No Mount): 1.02 ounces
Objective Lens Size: 22 x 15 mm
Dismount to Replace Battery? No, Top Fill
URL: swampfoxoptics.com
MSRP: $249 (plain), $294 (with shield)

swampfox liberty mrds

Swampfox is a newer company, but they’re very ambitious about regularly releasing improved optics. Their first pistol MRDS was the Kingslayer, a not-so-subtle hint at trying to take down the Trijicon RMR, with which it shares a footprint. Their latest CCW-oriented MRDS is the Liberty — little brother to the duty/competition, Justice. 

You need a small flathead screwdriver to make adjustments. Though there’s a guide, adjustments are neither tactile nor audible.

An optional accessory for the Liberty is the Ironsides Shield for extra durability. This stainless shield is designed to route impact stresses from the optic to the footprint itself. There are dual buttons on the left side of the optic to both turn it on and adjust brightness. There are 10 brightness settings and no auto-adjust. After four minutes of no motion, the illuminator will shut off and then instantly wake up with any movement. 

Color rendition is excellent, and there’s an ever-so-slight horizontal refraction present.

For batteries the Swampfox Liberty uses a CR1632 and is replaced from the top with the assistance of a T10 Torx wrench.

[How-To] Install a Handguard on an AR-15

https://www.pewpewtactical.com/wp-content/uploads/2021/04/Barrel-installed-2048×2048.jpg

Installing a handguard is one of the steps in building an AR that people seem to fall short of.

The overall process is straightforward, but there are little details in every step that make or break a proper install.

But that’s why you have us, right?

350 legend midwest slh handguard
Are you ready to change things up with a new handguard?

For this article, we’ll cover the steps of installing a handguard on a new receiver using a barrel nut — not a delta ring.

So, let’s get down to the nitty-gritty of installing a handguard on your AR.

Table of Contents

Loading…

Tools You’ll Need

There are a few key tools you’ll need on hand to install your handguard.

Bonus Items

For more parts and tools you might want to have for future tweaks and builds, head over to our AR-15 Parts & Tools List.

Removing Existing Handguard & Hardware

Step 1: Take Off Old Handguard

If you are starting fresh with no handguard, then skip on down to installing your handguard.

However, if you’ve already got a handguard in place that you need to swap out, start here.

Best AR-15 Handguards
Regardless of which handguard you choose, you gotta remove the old one from your AR.

You’ll need to first remove the existing handguard with a handguard removal tool.

Step 2: Separate the Upper & Lower

To make the installation process easier, go ahead and remove the lower receiver and set it aside.

From here, you can use a vise grip to clamp down on the upper receiver.

Step 3: Remove Muzzle Device, Gas Block & Barrel Nut

Continue the disassembly process by removing any existing muzzle device and hardware, gas block, and barrel nut.

You’ll need to tap out the gas tube roll pin with a #2 pin punch. From here, take a look at the front sight gas block. If it has tapered pins, you’ll need to go ahead and drive them out. 

If you opt for a clamp-on style block, use a hex key to loosen the set screws.

Remove the gas tube.

Finally, remove the original barrel nut with an armorer’s wrench.

Then make sure everything is properly cleaned and degreased.

Installing a New Handguard

Step 1: Test Fit Barrel

The first steps of an install will be the foundation for success.

So, let’s start off right by test fitting your barrel into the receiver.

This may require some thermal fitting, depending on the brands you use. As such, I wait until after I test fit before degreasing.

Barrel installed
Barrel installed.

If the barrel installs without any heat needed, remove it, and degrease the receiver threads and the barrel nut for your handguard.

I will note that wearing some sort of latex or synthetic gloves will help to prevent more oil from your skin from corrupting your work.

Step 2: Install Barrel & Apply Aeroshell 33MS/Aeroshell 64

Once the parts are degreased and have dried, install your barrel.

Apply some Aeroshell 33MS/Aeroshell 64 to the receiver threads and the barrel nut threads.

The use of Aeroshell is one detail that is often overlooked.

Aeroshell
Aeroshell

First, the torque values given here are wet values, meaning they need some sort of lubrication to properly achieve those numbers.

Equally as important are fighting galvanic corrosion and making sure the barrel nut doesn’t seize over time.

Galvanic corrosion can occur when two different metals are in contact, and an electrolyte causes one to corrode in preference to the other.

Now, depending on the area of the world you are in, this may not be much of an issue; here in the Nevada desert, it isn’t a huge risk, but I’d rather be safe.

Applying Aeroshell
Applying Aeroshell

One further note: There is a difference between Aeroshell 33MS/Aeroshell 64 and anti-seize, such as that for ball-bearings or Permatex.

Many anti-seize agents contain graphite which is counter-intuitive to what we are trying to do here as graphite can promote galvanic corrosion.

Stick to the proper agent, as Aeroshell is readily available.

Step 3: Attach Barrel Nut & Torque Down

After you have properly applied your Aeroshell, the next step is going to be attaching the barrel nut and then torquing it down.

Slide the barrel nut over your barrel and hand tighten it a few turns to get it engaged on the threads.

At this point, I am a huge fan of using the Midwest Industries Upper Receiver Rod for the remainder of the process.

With the spine built into the URR, it allows for proper torque without much risk of damaging your barrel index pin or receiver.

Using your armorer’s wrench or a barrel nut wrench that came with your handguard, apply some torque, back it off to loosen, and repeat this a few times to season the threads.

Torquing barrel nut
Torquing barrel nut

After three to five low torque value tightenings, you will hand tighten the barrel nut.

Using a torque wrench, tighten to your final value. This can range from 30- to 80-foot-pounds of torque depending on the barrel nut.

Pro tip: Read the instructions from the manufacturer on the appropriate torque value.

Step 4: Install Gas Block

With your barrel nut properly greased and torqued, the next step is installing your gas block and then your handguard.

Again, there are some small details here that often get missed. They can make a huge difference in the final product.

Checking gas block alignment
Reinstall your gas block and make sure to check its alignment.

For help installing your gas block, check out our article here.

Step 5: Install Handguard

With your gas block properly installed, you’ll slide the handguard over the barrel and gas block, seating it against the receiver.

The number of handguards and styles available in the market results in many variables on this next step.

Double-check the alignment of the handguard to the top Picatinny rail of the receiver.

checking top rail alignment
Checking top rail alignment.

They should line up equally without any change to the angle of the Picatinny rails.

Some handguards use indexing tabs or anti-rotation tabs to keep things aligned. Others use mounting hardware designed to achieve the same result.

Regardless, ensure that the Picatinny rails line up properly before moving on.

Step 6: Secure Handguard

With your handguard indexed properly, so the Picatinny rails line up, you’ll want to secure it with the mounting hardware.

This can vary greatly from one manufacturer to the next but will almost always involve using screws.

Make sure the screws, as well as the screw holes, are properly degreased and dried before moving on.

I will stress one important note for the next step.

Applying blue loctite to mounting screws
Applying blue Loctite to mounting screws.

Thread locker has been an issue of some debate lately. For handguard mounting screws, I have always used Loctite Blue 242 with great success.

Others say you should use Loctite Red 271 or Vibratite VC3.

I have not found heat causing screws to loosen on a handguard to be an issue if properly torqued.

If you do see an issue, use the Red 271 and understand that heat will have to be used if you ever need to change things.

The only exception to using thread locker that I have come across is installing the Centurion Arms CMR rails — which I highly recommend.

Installation instructions specifically note that the use of thread locker on mounting screws for this rail will void the warranty. So, again, always read manufacturer instructions before you install.

Using an appropriate thread locker on the mounting screws, you’ll want to install them snug but not torqued down in a criss-cross pattern.

As you install the screws, check to make sure the position of the top rails has not shifted and things still line up.

Proper mounting hardware
Proper mounting hardware

Once all the screws are in and hand snug, you’ll begin the process of torquing them down in the same pattern — still checking the top rail alignment has not shifted. 

The torque value on these screws can vary but usually falls somewhere in the 25- to 45-inch-pounds of torque.

I feel like I’ve said this before, but…read the manufacturer’s installation instructions for proper values.

In some cases — such as the Centurion CMR or the Dirty Bird Industries SMRS — there will not be an alternating pattern to the screws but rather a few on the bottom.

So, make sure you know which screws should be tightened down first and to what torque value.

Step 7: Install Muzzle Device & Accessories

With the handguard attached and the mounting hardware torqued down, the only things left are to install the muzzle device and any attachments you desire.

Timing a muzzle device is something that is better suited for another article. But the main point to monitor would be to degrease the barrel thread and muzzle device threads before applying Rocksett. Then torque to manufacturer specifications.

Tested Muzzle Brakes
Needs some recs on the best muzzle brakes? Read our article here!

When installing accessories, have a rough idea of where you want things like foregrips, flashlights, and slight attachment points to go.

Planning out locations before you start installing things ensures they don’t interfere with components under the rail.

I’m here to tell you that size does matter in some cases. People frequently try to install foregrips but end up hitting the gas block with mounting screws.

Sometimes small location changes are required.

After your components are attached, and thread locker has cured, you are done!

All that’s left to do is toss the lower receiver and upper receiver back together.

Conclusion

Installing a handguard doesn’t have to be a scary process. Using the steps above, you can easily add a handguard to your AR build.
