My new Calguns lower got some test firing today, took the upper off my previous build (JD upper, Colt BCG and Bravo Co. 16" barrel w/ BTE adjustable gas block) stuck my new Aimpoint PRO onto it and ran about 60 rounds throught it, ran like a watch.
On the Calguns receiver i decided to do things a little differently, the parts kit was RRA with thier 2 stage trigger and instead of using roll pins I tapped the bolt catch hole for 4-40 set screws and used some 3/32 drill rod sandwiched between the 2 screws.I also put a set screw into the rear take down pin spring hole. I just got a YHM upper for the calguns receiver but no barrel decisions yet.
