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.
