Description

Aim7 PepperBox Plan-B Muzzle Brake (1/2×28 & 5/8×24) & Bravo HUB Adapter Combo Kit

Upgrade your host platform with the Aim7 PepperBox Plan-B Muzzle Brake & Bravo HUB Adapter Combo. Engineered for rapid-taper mounting, repeatable point-of-impact (POI), and heavy-duty gas dispersion, this complete pairing delivers seamless compatibility between your 1/2×28 or 5/8×24 host firearm and industry-standard 1.375×24 Bravo / HUB modular hardware.

By coupling the 360-degree radial porting of the 4140 steel PepperBox brake with the high-strength stainless steel Plan-B Bravo adapter, this kit provides smooth recoil mitigation, protects external threads from carbon fouling, and serves as an effective sacrificial blast baffle for high-pressure setups.

Key Combo Features

• 360-Degree Radial Gas Dispersion: The “pepper pot” port matrix vents high-pressure gases symmetrically in all directions to flatten recoil impulse and minimize muzzle rise.
• Concentric Plan-B Taper Lock: Precision-machined forward taper aligns on a taper-on-taper interface for dead-repeatable POI lockup while sealing gas tight to prevent carbon accumulation on threads.
• Bravo / 1.375×24 Universal Interface: Adapter body threads into any standard 1.375×24 Bravo/HUB socket, mating instantly with Plan-B / Cherry Bomb pattern muzzle devices.
• Sacrificial Baffle Protection: The heavy-duty 4140 steel brake acts as an internal sacrificial shield, absorbing harsh unburnt powder jet erosion before it contacts blast chambers.
• Short-Barrel Tested: Rigorously tested and fully rated for short barrels down to 7.5″ (.223 / 5.56, 9mm) and 8″ (.300 BLK / .30 Cal).
