AR-45 Complete Upper Receiver

As with all quality weapons, you have to start with a solid base and our AR-45 complete upper receiver is precision CNC-machined from solid aerospace billet aluminum. This is a top-tier AR-45 complete upper receiver perfect for any high quality AR-45 build. Add to that, our Juggernaut Tactical 15" free float hand guard and you have a very attractive, functional and lightweight precision weapon. We use our own 16" Nitride Lightweight Barrel with a 1:10 twist in combination with our anti-bounce bolt carrier group. Together, these make one of the smoothest operating AR-45 uppers around.
