Description
The Gemtech GVAC Upper Receiver Assembly delivers a complete, ready-to-install solution for AR-15 platform builds chambered in 5.56x45mm NATO and .223 Remington. This assembled upper comes complete with bolt carrier group, so you can complete your build with minimal additional parts procurement.
Built around a 16.1-inch barrel featuring a 1-in-8" twist rate and finished in Armornite, the GVAC system utilizes a mid-length gas configuration for smoother cycling and reduced felt recoil. The 15-inch Midwest M-LOK free-float handguard provides a modular attachment platform along its full length for lights, grips, and other accessories.
Topped with Gemtech's own ETM Flash Hider, this upper receiver assembly offers reliable AR-15 pattern compatibility in a complete, factory-assembled package.
