Five Stone Tactical Jet Drive Brake - Dual Port 1/2-28 HT - Plan B Muzzle Device

Five Stone Tactical Jet Drive Dual-Port Brake - 1/2x28 - Heat Treated

The Five Stone Tactical Jet Drive dual-port brake with a Heat Treated finish combines a purpose-built muzzle-brake layout with a Plan B-compatible suppressor mounting interface. This exact configuration uses 1/2x28 barrel threads and is manufactured from 17-4 PH H900 stainless steel for a durable, high-performance component at the muzzle.

The dual-port geometry provides the defining Jet Drive configuration while preserving compatibility with Plan B-type mounts and adapters. A shim kit is included to support correct timing on a barrel with the matching thread pitch. Thread pitch alone does not establish caliber or bore compatibility, so the complete barrel, projectile, suppressor, and mount system must be verified before installation.

Configure the muzzle device and suppressor mount as one system. Choose the 1/2x28 Heat Treated Jet Drive dual-port brake at BattleHawk Armory after confirming barrel threads, bore clearance, and Plan B fitment.

Dual-Port Muzzle-Brake Configuration

The dual-port layout gives this SKU its specific gas-port configuration. As a muzzle brake, it provides a functional muzzle device when the suppressor is removed while retaining the external interface required for a compatible Plan B-type suppressor mount. The design lets a single component serve as both the brake and the mounting point within a verified suppressor system.

Plan B-Compatible Mounting Interface

The Jet Drive is built for Plan B-type suppressor mounts and adapters. Plan B compatibility is interface-specific and does not mean every suppressor, adapter, or similarly shaped taper mount will fit. Confirm the mating adapter, thread direction, internal clearance, and suppressor manufacturer's restrictions before assembly.

17-4 PH H900 Stainless Steel

Precision-machined 17-4 PH H900 stainless steel provides a sophisticated balance of strength, heat resistance, and dimensional stability for a muzzle-mounted part. The Heat Treated finish identifies this variant and provides the intended exterior treatment without changing its stated 1/2x28 thread or dual-port configuration.

Shim Kit for Timing

The included shim kit supports rotational timing of the brake on the barrel shoulder. Use only appropriate shims, maintain full thread engagement, and avoid improvised washers or stacked parts that prevent proper seating. Correct timing and alignment are essential for safe function, especially when a suppressor will be attached over the muzzle device.

Installation and Fitment

Install only on a barrel with verified 1/2x28 threads and a compatible shoulder. Confirm the device bore is appropriate for the intended projectile, check suppressor blast-baffle clearance, and use an alignment rod suitable for the caliber and suppressor. Follow current installation instructions and use a qualified gunsmith when thread condition, timing, or alignment is uncertain.
