Introducing Gemtech 13833, an innovative product from our Gvac system line. This design is patented specifically to considerably mitigate the amount of gas blowback you may come across whilst shooting in suppressive conditions. The Gvac system comes with a revamped barrel profile, improved bolt carrier profile, amplified bolt carrier group, and an ETM muzzle device to guarantee not just elevated performance, but to ensure that nothing stands in your way.

Elevate your shooting experience with our next-level suppressed system, the Gvac. Our product comes with an Upper Receiver, designed to Mil-Spec standards with Indexing Marks, and M4 Feed Ramps, all made from 7075-T6 Aluminum, and Anodized with Type III Hard Coat. Additionally, the Barrel, made from stress-relieved 4150CMV Steel, Armornite treated with a 1:8 Twist, is 5rd Rifled, Gvac Profiled, with a Nickle Boron Coated Barrel Extension, and 1/2X28 TPI Muzzle Threads.

Our GAS System consists of our Pinned Low-Pro Gvac Gas Block and Mid-Length GVAC, both made from 4140CM Steel, and a Direct-Impingement Muzzle Device. The former features a Gemtech ETM Flash Hider, crafted from 4140CM Steel, and a Bolt Carrier Group composed from a Carpenter 158 Steel Bolt and 8620 Steel Carrier, both Mil-Spec MP Tested, with a Mag-Phos Finish, Chrome Lining, and a Properly Staked Gas Key.
