Notable YouTube personality Iraqveteran8888 is back with another one of his popular full-auto meltdown tests. Previous installments have included a Lewis Machine and Tool Piston Upper, WASR-10 AK, Glock 17 Gen3, Patriot Ordnance Factory P416 and others. His latest victim? The Smith & Wesson M&P15 Sport II, an entry-level AR with a MSRP of $739.

In the video above, Eric combines the M&P15 Sport II upper with a registered full-auto lower provided by the folks at Quiet Riot Firearms in McDonough, Ga. He also swaps out the M&P bolt carrier group for a Palmetto State Armory full-auto BCG to ensure functionality with the machine gun lower.
