Dual, curved restrictor plates with a tremendous amount of surface area stop exiting barrel gases and pull the barrel forward to counteract recoil and muzzle flip. The front sight or scope stays right on target for a faster second shot, plus less felt recoil and shooter fatigue. Models available for rifles chambered in .308/7.62mm. 5/8-24 TPI is the industry standard for AR-10-type rifles and also appropriate for custom applications. The .750 outside diameter is designed for standard military contour barrels, but can be tapered down for smaller contours. The JPRE-424MG has a final exit hole of .350 and can be enlarged to accommodate bores up to .400. The JPRE-428 Mfg: J P Enterprises
