Was in a local shop and have been debating on an AR build. Well they had a Complete RRA lower with just a standard trigger and 6 Position stock for $324 which was a decent price to me so I snatched it up. Anyway am considering a Grendel build and am new to the whole built it aspect as well. Was originally planning a forged lower and buying parts kits and doing everything seperately but being the first AR I figured I would keep the lower simple for now and possibly upgrade down the road. Can anybody clarify to me if the RRA complete lowers are Milspec or Commercial? Cant find much info on their site. Also what buffer and will it be compatible for a 6.5 Grendel/
Appreciated
