Gemtech Series GVAC 5.56 Upper | Guns & Gear
This video introduces the Gemtech G-VAC upper receiver, specifically designed to optimize AR-15s for suppressed shooting. The core innovation is the gas bore evacuator system, which significantly reduces gas blowback into the shooter's face without requiring manual adjustment of the gas block. This allows for reliable operation whether the firearm is suppressed or unsuppressed, simplifying the shooting experience.
