The Rearden 10174 PRS 0.28 1/2x28 Square Plan B Muzzle Brake is engineered for shooters who demand precise suppressor mounting and consistent recoil control. Machined from 17-4 PH H900 stainless steel and finished in black nitride, this square-profile brake interfaces seamlessly with Atlas, Atlas XL, and Plan B-style mounts while providing a robust sacrificial blast baffle in front of your suppressor.

This model is ideal for rifles using 1/2x28 threads and .223/5.56-class projectiles, offering a .280 bore and 2.25-inch overall length to balance control and compactness. Its design supports range use, training, and competition where repeatable point of impact and smooth follow-up shots matter.
