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 Jacob Grey Billet Aluminum Upper Receiver features a No forward assist function due to the exacting tolerances and reliability of its functioning.
