The VG6 EPSILON is the pinnacle of AR15 muzzle devices. The EPSILON challenges the status quo and offers performance beyond that of a traditional muzzle brake. Designed for the avid shooter and professional end-users, VG6 Precision's EPSILON affords you the best muzzle control and recoil mitigation the industry has to offer. This is a true combination muzzle brake / compensator / flash hider. The VG6 Epsilon carries many of the same characteristics as the Gamma with a few exceptions. Extended flash hiding prongs and no ports at the 12 o'clock positions allow uninhibited view from flash through optics or sights giving the shooter maximum visibility without compromising recoil control capabilities. Updated chamber design features improved gas flow and rigidity. By leveraging modern design principles both functionally and aesthetically, we continue to keep the VG6 product family at the cutting edge of muzzle device performance.
