Description
Maximize your 9mm’s accuracy.
This AR9 pistol upper features a 10.5″ barrel forged from 4150 CMV, maximizing 9mm’s muzzle velocity, range, and accuracy. Paired with a free-floating 9.5″ M-LOK barrel and M4 flattop receiver, this upper provides plenty of rail estate for all your optics and accessories.
Lastly, this upper ditches the AR’s old charging handle for a new, right-side charging handle that’s far more ergonomic and easier to charge. Accuracy and ergonomics, rolled into one.
What’s Included
This is not a firearm. It includes an assembled upper receiver, bolt carrier group, and charging handle.
