Aim7 PepperBox Plan- B Muzzle Brake 1/2×28

Aim7 PepperBox Plan- B Muzzle Brake 1/2×28

Design & Features

• Plan-B Interface: Features external threads and a tapered shoulder to create a tight, concentric seal with Plan-B suppressor adapters, ensuring a secure lock-up and preventing carbon from fouling the threads.

• 360-Degree Porting: The distinctive “pepper pot” radial hole pattern evenly disperses expanding muzzle gases in all directions. This mitigates felt recoil and acts as a sacrificial blast baffle to extend the life of your suppressor.

• Wrench Flats: Integrated hexagonal flats at the base allow for straightforward torquing and installation using a standard wrench.

• Mounting Hardware: The device is accompanied by a heavy-duty lock nut and a beveled ring/crush washer to assist with proper timing and secure fitment to the barrel.
