Product Description

The Gemtech GVAC upper receiver group is engineered to enhance suppressed shooting by significantly reducing gas blowback through its patented GVAC design. This complete upper features a Mil-Spec 7075-T6 aluminum receiver with indexing marks and M4 feed ramps, paired with a stress-relieved, Armornite-treated 4150 CMV steel barrel. A mid-length, direct-impingement GVAC gas system with a pinned low-profile gas block helps optimize reliability and performance, while the included enhanced bolt carrier group and Gemtech ETM flash hider round out a purpose-built package for AR-platform builds and upgrades. The 15-inch Midwest Industries Combat free-float M-LOK handguard provides versatile mounting space with a continuous Picatinny top rail and integrated QD sling sockets.
