Retro Conversion by Nitrous-Noel, Verified Owner, March 9, 2024
I wanted to buy a retro rifle for about 2 years. I couldn't find one worth their asking price, so I bought 2 of these Rock River Arms A2 uppers. I built one national match A2 upper to build a 20" and one regular A2 upper for a 16" (true) dissipator.
