I have an AR-15 made from an RRA lower and Olympic upper. The BCG is from White Oak Armament and the barrel is a heavy profile and 1:9" twist. It has an ergo grip and a full length forearm picatinny rail. This rifle only has 120 rounds through it. I'm looking to trade for a nice AK-47. I might consider a Mini 14, or HK type of rifle. Let me know what you have for trade!
