"Overall I like this upper with only minor reservations. First, fit and finish are top notch. Gas block is pinned and the coated bolt carrier is also a nice feature. Function has so far been flawless, and accuracy is better than expected, quite good actually. Make sure you use an H2 buffer. Contrary to the description it is a pistol length gas system. The negative is the proprietary flash hider and barrel nut. The tools to disassemble this upper are expensive(for one use tools). Did not think of that before buying. For context I build/collect and shoot on weekends, not a professional gunsmith/shooter. Lastly, know your laws before buying."
