The VG6 Precision EPSILON 762 is a high performance muzzle brake for eliminating recoil. Compatible with most common .30 caliber chambered rifles, this hybrid device features both recoil compensation and flash signature mitigation in one package. With a continued focus on improved recoil control, the EPSILON 762 features a new enhanced chamber design that improves gas flow and felt recoil measurably over previous versions. We have also focused on saving weight through both the chamber design and aggressively cut channels along the length of the device.Following the success of the GAMMA 762, the EPSILON 762 provides an additional offering with distinguishable features for the growing M5/AR10/.308 platform.This product was designed using state of the art engineering techniques, utilizing CFD (Computational Fluid Dynamics) and CAE (Computer Aided Engineering). This product is 100% CNC machined for optimal performance.Features: Material: 17-4ph(R) Heat Treated Stainless Steel Finish: BLACKNITRIDE(TM) Surface Hardness: 68RC Caliber: 7.62mm only Thread: 5/8x24 RH Weight: 2.6oz Includes crush washer
