Aim7 H-3 Plan B 3-Ports Muzzle Brake 5/8×24

Aim7 H-3 Plan B 3-Port Muzzle Brake 5/8×24 (.30 Cal / 7.62 / .308 / 9mm)

The Aim7 H-3 Plan B 3-Port Muzzle Brake is an ultra-compact recoil management device engineered specifically for the Plan B / Atlas mounting taper system. Designed for shooters who demand flat recoil tracking and rapid follow-up shots, this brake incorporates an optimized triple-port architecture that maximizes gas dispersion and dramatically reduces muzzle climb.

By progressively vectoring expanding gases through 90° horizontal baffle ports, the H-3 stages gas discharge: the initial port absorbs the primary concussive impulse, while the secondary and tertiary ports stabilize the muzzle. This delivers superior recoil mitigation while keeping your rifle balanced, flat, and ready for rapid taper-mount suppressor attachment.

Key Features & Performance

• Staged Gas Dispersion: Triple-chamber 90° horizontal blast-vectoring design progressively vents high-pressure gases to virtually eliminate felt recoil and muzzle rise.
• Plan B / Atlas Compatible: Precision CNC-machined external taper locks seamlessly into Plan B and Atlas style suppressor mounting interfaces for concentric, repeatable lockup.
• 17-4 PH Stainless Steel: Machined from heat-treated 17-4 stainless steel for extreme structural integrity, high thermal tolerance, and long-term erosion resistance.
• Ultra-Compact Footprint: Measuring just 1.96″ overall length and weighing a nimble 2.4 oz, it keeps your muzzle lightweight and maneuverable.
• Sacrificial Baffle Protection: Serves as an effective blast baffle shield, extending the service life of your suppressor’s primary blast chamber.
