.50 beowulf - American Tactical Imports AR-15 Stripped Poly Hybrid Upper Receiver

I used both the poly upper and lower to build my .50 Beowulf and it holds up great. So when people say it's cheap and can barely handle a 22lr, just think im out there with it and using a big round. Everyone who held it says they like the feel and weight of it. Im also running the hera arms cqc stock and forward hand grip.
