Please run by parts and ideas by us, it's what we are here for and like to do…. so no mistakes are made. While the M1A barrel could've gotten sent back, it would suck to have to pay all the shipping fees ect.. Remember when ordering, you want DPMS/SR25 platform capatibilty, and for places to look for parts, check our site sponsors, Rainier Arms, Fulton Armory, and try to stay away from GB and other auction sites.
