Details

The Regulator 4 Port Muzzle Brake is built for shooters who want maximum recoil reduction and muzzle control in a mounting‑system‑agnostic design. The 4 port brake direct gases to the sides, making the shooter experience less blowback and have a more comfortable shooting experience. This reduction in blowback felt through the porting effect of this brake helps reduce muzzle rise and improve shooter’s return to zero. CNC machined from 17‑4 stainless steel alloy and surface treated in black nitride, this brake uses an aggressive four‑port geometry to prioritize performance and repeatability through tight tolerances because of production method, and suppressor‑system compatibility across modern HUB and Xeno™ ecosystems. The brake performs excellently by itself as a standalone product but excels even further when paired with the LMT-AT HUB Base Mount Adaptor. Designed with a taper lock gas seal to provide a more secure connection for keeping gas chambered in & ultimately flow out of the suppressor. Any concerns around the suppressor mount adapter and muzzle brake unthreading are rectified due to the left-handed threads used to pair the brake to the LMT-AT HUB base. Shim kit included with packaging for brake port alignment.

What Makes This Different

  • Four‑port performance focus: Designed to aggressively counter recoil and muzzle rise for fast follow‑up shots.
  • Mount‑forward design: Fully compatible with HUB and Dead Air Xeno™ mounting standards.
  • Performance durability: 17‑4 steel with a black nitride finish for strength, corrosion resistance, and heat tolerance.
