Not bad for the price by daemon6, January 17, 2024

This isn't a bad muzzle device for the price. I would like to see ports on the top surface of this to help mitigate muzzle rise.. so I drilled two myself and it works much better now.

Product Info for Breek Arms 2BO 2 Port Muzzle Brake

The 2BO Double Port Muzzle brake was designed to reduce recoil and muzzle rise. This 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.

The brake is machined out of 4140 steel, heat treated for hardness, and nitrided to offer exceptional strength and durability. The 2BOs large 90 degree ports mitigate recoil and muzzle rise, countering the force generated through firing. This produces 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.
