Breek Arms 2BO-S Muzzle Brake | 5.56 | 1/2×28

The Breek Arms 2BO-S Muzzle Brake | 5.56 | 1/2×28 is a compact and efficient recoil-reducing device designed to improve control and reduce muzzle rise on AR-15 platforms. Engineered specifically for 5.56 NATO and .223 Remington barrels with a 1/2×28 thread pitch, this short-profile muzzle brake delivers performance without adding excessive length or weight to the end of your rifle.

The “2BO-S” stands for “Two-Port Blast Optimized – Short,” referencing the brake’s dual-port layout that redirects gases laterally to mitigate felt recoil and muzzle climb. This helps shooters stay on target through rapid strings of fire, making it ideal for competition, training, and tactical applications. Despite its reduced size, the 2BO-S achieves recoil control typically found in larger devices, offering excellent value in a compact footprint.

Constructed from heat-treated 4140 steel and finished in a durable black nitride coating, the brake resists corrosion, heat, and mechanical wear over extended use. Its CNC-machined precision ensures proper bore alignment and secure installation, making it safe for use with high-round-count setups and compatible muzzle accessories.

This model is particularly well-suited for rifle builds where overall length must be minimized, such as in SBRs or pinned-and-welded applications where space is at a premium. The flat face and clean lines offer a sleek look that pairs well with modern AR-15 aesthetics, while the optimized gas ports maintain comfort and safety during team or prone shooting.

Whether you’re fine-tuning a competition rifle or upgrading your defensive carbine, the Breek Arms 2BO-S Muzzle Brake delivers serious performance in a no-nonsense, compact design. It’s a top-tier choice for shooters who want recoil reduction and control without unnecessary bulk.
