Overview

Built for rifles in .30 caliber with 5/8x24 threading, this compact muzzle brake is designed for use with the Plan B mounting system and fast-attach suppressor setups. Its single-port layout and horizontal blast-vectoring ports are intended to help reduce recoil and muzzle rise while keeping the rifle flatter between shots. At 1.75 inches long and 2.0 ounces, it stays low-profile on the muzzle without adding much bulk. For hunters and shooters who want a brake that supports quick suppressor changes, it offers a purpose-driven setup with a straightforward, compact profile.

Considerations & Trade-offs

  • Designed around the Plan B mounting system, so it only fits rifles set up for that interface.
  • The single-port, ultra-compact format may offer less braking surface than larger multi-port brakes, which is a trade-off for size and suppressor compatibility.
  • Thread pitch is specified as 5/8 x 24 TPI, so it is not a universal fit and must match the rifle’s muzzle threads.
  • The product is listed for .30 caliber use, so it is not intended as a general-purpose brake across other bore sizes.
