The Gemtech GVAC 5.56 upper receiver is designed to significantly reduce gas blowback when shooting suppressed. Its core innovation is the Gas Bore Evacuator (GBE) system, which creates a vacuum to vent gases forward, minimizing their return to the shooter's face. This system allows the upper to function reliably with or without a suppressor without requiring manual gas adjustment, offering a set-it-and-forget-it solution for suppressed AR-15 platforms.
