So heres a project Ive been working on for a while, and I finally got all of the stuff together at the gun show today. Meet my old school AR-15. Its built on a Superior Arms lower with a Olympic lower parts kit. The pistol grip and buttstock are M16 GI. I assembled the lower myself. The upper is an old A1 upper with a Colt barrel I came across at the show today. The bolt and carrier assembly are a chrome Young bolt and carrier. Now all I need is a 60s vintage sling and Im ready to rock and roll!
