Upper in 7.62x39 - Radical Firearms AR-15 RF Upper Assembly 16in 7.62x39 w/ A2 Flash Hider

I was really surprised when I opened the box to this upper, I was hesitate to order a 200 dollar upper but it’s way more than I was expecting, the feed ramps look good on the barrel, the upper receiver looks as good as anyone else’s and the handguard os nothing fancy but looks and feels good, I slapped a prime weapons bcg and a mil spec charging handle, works like a champ, ran 30 rounds through it and did the barrel cleaning for new barrel break in no problems
