9mm AR 9 Upper Assembly – 16″ Parkerized M4 Barrel, 1:10 Twist Rate with 15″ M-LOK Handguard

Description

Stretch the 9mm cartridge to its limits with this 16″ 9mm upper. This rifle-length barrel maximizes muzzle velocity and spin rate to afford hole-punch accuracy beyond 100 meters. Paired with a monolithic BCG and heavy-duty 9mm buffer, this upper’s even easier to charge and it absorbs felt recoil better than any other 9mm platform on the market today.

What’s Included

This is not a firearm. It includes an assembled upper receiver, bolt carrier group, and charging handle.
