Hello everyone, I have just started my project build for my AR. I would like to build a complete XM16e style rifle with most parts being GI. To start with, all that I own is a PSA (Palmetto State Armory) Lower receiver in fine condition. Picked it up for $50 back a few months ago. I know most of you on here have built your own ARs and have seen way too many M1 builds, but one more wouldn't hurt. I believe i should start with my upper, bolt assembly and barrel next. These parts do not necessarily have to be GI. What do you think?
