Brownells 75th Anniversary - A Shooting Heritage

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 .223/5.56mm and .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 1.000 outside diameter will accommodate the heavy bull barrels common among long-range varmint rifles including, but not limited to, the M15 and AR10-type rifles.
  • The JPRE-324MG has a final exit hole of .350 and can be enlarged to accommodate bores up to .416.
