VG6 Precision Epsilon AK Muzzle Device Black. The EPSILON AK just outperforms everything on the market. Designed for the discriminating shooter and professional end-users VG6 Precision's EPSILON AK affords you the best muzzle control and recoil mitigation the industry has to offer. This is a true combination muzzle brake / compensator / flash hider. Its performance is matched only by the amazing look of this device. The VG6 Epsilon AK carries many of the same characteristics as the Gamma line of muzzle brakes with a few exceptions. Extended flash hiding prongs allow uninhibited view from flash through optics or sights. The difference in porting is noticed on the underside of the device where it has 6 valve holes to allow the fastest gasses reaching the second chamber to exit. This creates very soft low energy recoil that allows for absolute control. Indexing pin slot for standard AK47 muzzle device retention.
