AT3™ Assembled Pistol Upper for AR-15 – 10.5″ 5.56 NATO Barrel with 9″ SPEAR M-LOK Handguard
Built to Order – Ships Within 3 Business Days
This assembled upper delivers a compact, hard-hitting platform for AR pistol builds and SBR conversions. This is the foundation for shooters building a maneuverable home defense weapon, a truck gun, or a compact range blaster where you need something short but still want the reliability out of a 5.56. The 9-inch handguard keeps the overall length minimal while still providing room for essential accessories without getting in the way.
The 10.5-inch government profile barrel in 5.56 NATO pairs with a carbine-length gas system for reliable cycling with a wide range of ammunition, while the 9-inch SPEAR free-float handguard gives you enough real estate for a light and grip without adding unnecessary bulk.
Built on AT3’s slick side billet upper receiver with a low-profile .750 steel gas block and stainless gas tube, this setup is ready to run once you add your choice of bolt carrier group and charging handle. The AT3 Combat flash hider reduces muzzle flash and gives the muzzle a clean, finished look.
Note: Does not include bolt carrier group or charging handle. The upper is shipped fully assembled.
