I have several 20" AR-15's and decided this was one too many. Not clone correct by brand names, but a mix of parts to fill the visual role of a wall hanger. Brownell's 20" 1:7 twist barrel, Colt handguards,Toolcraft bcg, PSA A2 lower with safe/semi/burst markings (but semi auto function only).
The paint marker on the stock is one of the old rack numbers I was issued decades ago, but I can switch it out for a plain black stock if preferred. It only had one magazine fired through it to zero it and then confirm/have fun at 100 yards.
