LMT DEFENSE 5.56 NATO SHORT MUZZLE BRAKE 1/2X28 THREAD

The LMT Defense 5.56 NATO Short Muzzle Brake 1/2x28 Thread is a compact, high-performance muzzle device designed for shooters who demand maximum maneuverability without compromising durability, suppressor compatibility, or recoil control. Engineered to minimize overall weapon length, this short muzzle brake provides an efficient solution for carbines, short-barreled rifles, and duty-ready platforms where compactness is a priority. Compatible with the LMT ION Suppressor Series as well as HUB and Xeno suppressors, it incorporates LMT's advanced taper lock gas seal technology to help reduce blowback, flash, and sound signature when paired with a suppressor. The precision mounting interface also helps prevent carbon lock, particularly when used with LMT's RMSTD and RMSTDT suppressor bases, allowing for easier suppressor installation and removal after extended firing sessions.

Machined from premium 17-4 stainless steel and finished with a durable Black Nitride treatment and C-192 Armor Black coating, the 5.56 NATO Short Muzzle Brake is built to withstand harsh operating environments, high round counts, and demanding firing schedules. Extensive testing to military and NATO standards for durability, reliability, gas blowback management, flash reduction, accuracy retention, thermal response, and full-auto performance ensures dependable operation under the most challenging conditions. The precision-engineered design helps maintain consistent point-of-impact performance when used with compatible suppressors, making it an excellent choice for tactical, defensive, and recreational shooting applications. Proudly made in the USA and featuring standard 1/2x28 threading, the LMT Defense 5.56 NATO Short Muzzle Brake delivers a lightweight, rugged, and suppressor-ready solution for shooters seeking enhanced handling, reliability, and long-term performance.
