AR9 Right-Side Charging Rifle Build Kit - 16" Parkerized Barrel, 1:10 Twist Rate with 15" MLOK Handguard

Usually ships the same day or the next business day!

This AR9 rifle kit is a tactical shooter's dream come true thanks to its upper receiver. It’s designed with a right-side charging handle which will allow you to reload and charge your bolt while keeping your right hand on your grip, so you never have to remove your eye from the target. And with the ejection port on the right side, you won’t have to worry about shells getting caught on your gear.

But besides the upper receiver, we still got more to appreciate. It aslo comes equipped with a 16" parkerized barrel with a 1:10 twist rate paired with a 15" free-float M-Lok handguard. Included in the kit as well is state of the art lower parts kit and a 6-position stock and buffer kit.
