Does what it claims, but… by Hoodie, Verified Owner, December 23, 2023
The muzzle brake does ok in terms of reducing recoil, but does nothing for muzzle rise. It’s well made, coating is nice and not as large as I thought it would. Good for a short build. Overall the muzzle rise makes quick follow up shots harder. So bu...

Product Info for Breek Arms 2BO-S Short Single Port Muzzle Brake

The 2BO-S Single Port Muzzle brake was designed to reduce recoil and muzzle rise and keep your rifle footprint short. The recoil reduction allows the shooter to stay on target and take follow up shots quickly. This is important when speed and accuracy make the difference such as in competitive shooting or self defense situations.image

The brake is machined out of 4140 steel, heat treated for hardness, and nitride offering exceptional strength and durability. The 2BO-S has large 90 degree ports to mitigate recoil and muzzle rise countering the force generated through firing. This gives less blowback resulting in higher overall shooter comfort. It features a sleek design that integrates seamlessly with any system, maintaining a clean appearance that looks great on any firearm.
