Product Info for Jacob Grey Firearms 5.56 NATO Complete Upper Assembly

The Jacob Grey Upper Receiver is chambered in 5.56 NATO and built around a 1/7 twist barrel. 7-sided M-LOK Handguard and 7075 Aluminum Upper Receiver. These uppers have a pistol-length gas system that is combined with a low-profile gas block, which provides reliability under any condition. The handguard provides a tactical picatinny rail along the top which allows room for front and rear sights and reduces weight due to less material than standard full length picatinny rails. This upper receiver also includes the JG 7075 billet machined aluminum dust cover which gives this Upper Receiver a sleek perfectly matched look that would be a worthy addition to any quality build. The Jacob Grey Billet Aluminum Upper Receiver features a No forward assist function due to the exacting tolerances and reliability of its functioning.image

To prevent any confusion, the purchase of all Jacob Grey Complete Uppers includes the Jacob Grey ambidextrous charging handle & F/A rated BCG.

NOTE: Complete uppers with barrels under 16 in length are only for use on AR-15 pistol lowers, legal Short-Barreled Rifles (SBR), or must have a muzzle device permanently attached to bring the length to at least 16.

DISCLAIMER: Firearm specifications are subject to change at any time based on availability and supply chain shortage.
