Angstadt Arms 6" 9Mm Complete Upper Assembly W/ Bcg - Surpressor Ready

The Angstadt Arms 6" 9mm complete upper assembly delivers a compact, ready-to-run solution for pistol-caliber AR builds. This upper comes fully assembled with barrel, bolt carrier group, and hand guard—everything you need to mate to a compatible lower receiver and get on the range or in the field. The short 6-inch barrel makes this upper a natural fit for home defense, truck guns, or tight-quarters applications where a full-length rifle isn't practical.

Built with a suppressor-ready design, the upper features a 3-lug interface that lets you thread on a quality 9mm can for subsonic shooting and reduced signature—ideal if you're looking to run this setup quietly. The 5.5-inch ultra-light hand guard keeps weight minimal while giving you real estate for mounting lights, lasers, or other accessories. Angstadt Arms equipped this upper with a Radian ambi charging handle, so you can run it southpaw or right-handed without fumbling for controls.

Whether you're building a dedicated PCC (pistol caliber carbine) for 3-gun, a truck-ready home defense rig, or a suppressed training gun, this complete upper handles the heavy lifting. Just add a 9mm lower and magazines, and you're ready to shoot.
