B&T 2-chamber compensator, M.A.R.S .223 Remington, for thread 1/2"x28

Available from stock with us. Please pay attention to the respective delivery time indication!

The B&T 2-chamber compensator with M.A.R.S. interface is a muzzle brake designed for the mounting of suppressors and "Blast Deflectors". The B&T proprietary M.A.R.S. offers the user a slim and one-handed operable locking mechanism for the suppressor on the respective weapon.

Please note:
The variants marked with M15x1 HK fit ONLY on weapons with a step behind the muzzle thread such as HK MR223 & MR308. These variants do not fit on M15x1 standard threads.
Not compatible with the Haenel LR/ONE - the muzzle thread on this weapon is too short!

The Swiss company B&T AG (formerly Brügger & Thomet) has been in existence since 1991. Originally known for its suppressors, B&T also develops suitable mounts, handguards, and grips for various weapon systems due to governmental and military inquiries. The high quality and robustness of their products have found worldwide acceptance, leading to the development of their own weapon systems. The reliable self-loading rifles, which initially served for governmental use, are now also available for the civilian market.
