12.3" Carbine Upper Receiver Group (no BCG or charging handle) (Pistol/NFA)

(No reviews yet) Write a Review

We are very proud to be bringing this 12.3" carbine upper receiver group to you! Built from an Aero Precision upper receiver, Ballistic Advantage Hanson 12.3" barrel, and a Bravo Company USA M-LOK Compatible Modular Rail (MCMR), this is the ideal upper for your pistol or NFA carbine. Compact enough to be easily maneuvered in tight spaces, but with just enough extra barrel length to increase dwell time, resulting in a less temperamental upper than a 10.3" barrel.

The Ballistic Advantage barrel is cut in the proprietary Hanson profile, with a 1/7 twist to stabilize those defensive rounds. They are high pressure tested and magnetic particle inspected and nitrided for long-term durability. The gas block is pinned for additional reliability.

The MCMR is known for its tight lock-up on the barrel nut, resulting in an incredibly stable rail system for mounting your lights, sights, and lasers.

We think you'll be impressed with the way this upper handles and functions. Get one while you can!
