Great Upper Combo
The new AR9 build went together great. Wouldn’t hesitate to buy again.
USUnbeatable fit and finish; Great slim profile; Awesome service
This upper combo is almost unbeatable for the price - aero quality and awesome slim profile with ergonomics at the forefront. Obviously, be conscious of the gas block you use as it must be a legit low-pro. I'm gonna get the FDE m5 version at some point. Oh, and don't forget the awesome service from the guys, here.
USOne of the best
Shipped fast. The handguard was the perfect fit to my build. Light and sturdy
