howl's Review of Aero Precision M4E1 16in .300 Blackout Barrel Complete Upper Receiver with Flash Hider

Really love this aero precision 300 blackout upper, very sleek and lightweight, perfect way to upgrade and modernize an AR15. Fits my Rock River Arms 223/556 lower perfectly looks like a new rifle. Love the rail upper picatinny and 3/4 MLOK.
