So here is my first attempt at building part of an AR. I have always put parts on but this was my first ground up. Got a RRA lower from Yooper time, Picked up a CMMG parts kit for $60 at the gun show. Had a RRA butt stock laying around so I got a ATI 6 position tube kit for $48 from MidwayUSA. Lower total cost $237 (excluding tools I bought for assembly purposes) I totally wanna do it again!!!
