Who said 9mm couldn't ping steel at 300 meters?
Ignore those people, you don't need that kind of negativity in your life. Enter the 16" AR-9 rifle upper. It's capable of slingin' Parabellum at some pretty insane distances, maximizing muzzle velocity for downrange power. Features a slick side-charging forged upper, free-float handguard, and ramped 9mm BCG. Compatible with all current 9mm AR lowers.
PLEASE NOTE: This is not a firearm. This is only a prebuilt upper assembly. It includes an assembled upper receiver, bolt carrier group, and charging handle.
