NOTE: This upper assembly has a barrel less than 16” in length. These uppers are intended for use in AR-15 pistols or legal short-barreled rifles. Other configurations may violate Federal law.

With the Geissele Automatics Super Duty Barreled Upper Receiver, you can build the custom, short-barreled rifle (SBR) of your dreams. This stripped upper doesn’t include a charging handle, bolt carrier group (BCG), or muzzle device, so you can add the components that best suit your needs. The 14.5″ 5.56 NATO barrel is perfect for close-quarters situations, and can be pinned and welded to meet NFA requirements. Geissele’s 1-7 rate of twist and 1-2/28 threaded muzzle ensure compatibility with a wide range of muzzle devices. Order your Super Duty Barreled Upper Receiver today and start building your dream SBR!

This stripped upper receiver allows for a dust cover and forward assist button to be purchased separately, and features M4 feed ramps and mil-spec standards for a high-quality, custom build. The Picatinny rail on top is perfect for mounting iron sights, red dot optics, or rifle scopes. For best results, pair this upper receiver with the matching Geissele Automatics stripped super duty lower receiver in desert dirt color. The anodized finish is durable and will stand up to normal wear and tear.
