Review update - Optics Planet Exclusive Aero Precision AR15 16in .223 Wylde Fluted Barrel Complete Upper Receiver with Flash Hider

I bought a VG6 precision Gamma muzzle brake for this Aero Precision assembled upper. I clamped down the upper and placed an appropriate wrench to take off the Aero supplied A2 flash hider and found that it was barely hand-tightened to the barrel and the crush washer pristine. To say I was surprised is an understatement and I'm glad that I did not test fire before deciding to swap muzzle devices. I guess it demonstrates that we should not take for granted that pre-assembled items arrive perfectly assembled. Do your due diligence.
