ULTIMATE AR-15 MELTDOWN!

In this video we attempt to burn out an AR-15 upper on an M16 lower. We are testing the durability of not only the upper receiver assemby but few specific products as well including the SRC Relia-Bolt BCG, Geissele Super Gas Block, and one of the most affordable AR barrels on the market from Faxon Firearms. The results may surprise you. Special thanks to Jake over at Quiet Riot Firearms for his help i
