Iraqveteran8888 is at it again. This time he melts a Smith & Wesson M&P 15 Sport II AR-15.

The rules of meltdown videos are rather simple: An AR-15 upper is placed on a fully automatic lower. Magazines are pre-loaded, and the rifle is fired until it stops working. Often, the gas tube fails; sometimes a bolt may fail… whatever it may be that stops the rifle from functioning.

When the rifle can no longer be fired, the number of rounds run through the rifle are counted.

Smith & Wesson M&P 15 Sport II Specifications

From the S&W website:

• Caliber: 5.56mm NATO/.223
• Capacity: 30
• Safety: Manual Safety on Lower
• Barrel Length: 16″
• Overall Length: 35.0″
• Front Sight: Adj. A2 Post
• Rear Sight: Folding Magpul (MBUS)
• Action: Gas Operated Semi-Auto

Now for the video.

For a rifle that costs between $580 – $620, that is excellent performance.

On a personal note I like that the sport II is available in different configurations:

• No sights and standard handguard.
• Factory sights and standard handguard.
• Factory sights and Magpul handguard.

Round count was 820. Aside from the meltdown, there was not a single failure, such as fail to feed or fail to extract. That is a testament to the reliability of the S&W M&P series of rifles.

After watching the video, I am seriously considering the Smith & Wesson M&P 15 Sport II for my next AR-15.  If it took 820 rounds of full auto to break the rifle, chances are it would last me a lifetime.
