I have been building ARs on the lower receivers I bought about 3 years ago - while I still can! So far, other than .223, I have bought dedicated uppers in 9mm, 22LR, and 5.7. I'm interested in a 5.45 ver but haven't found any company building complete uppers. Anyone know?
It's too late for me, save yourself.
