BANISH® Suppressors Replacement Piston – .45 ACP for BANISH 45/46 – Black – 5/8X24 Thread Pitch – 100000310932
The BANISH® Suppressors Interchangeable Booster Piston (100000310932) is a specialized, match-grade NFA firearm accessory masterfully engineered to expand the operational envelope and multi-caliber utility of your modular silencer system. While large-bore pistol suppressors are highly versatile on paper, deploying them across a diverse fleet of weapons requires a highly secure, true-concentric mounting interface capable of handling both heavy thread structures and the precise inertial requirements of semi-automatic platforms. The BANISH conversion piston completely satisfies those technical needs. This heavy-duty booster hardware (810171221421) drops straight into your existing booster housing to deliver absolute tracking security and reliable semi-automatic functionality loops.
The structural foundation of this precision component is CNC-machined from a premium block of solid, heat-treated steel alloy. Chemistry-optimized by Silencer Central to comfortably withstand continuous exposure to intense thermal energy, high-pressure gas expansion, and unburnt abrasive powder particles, it retains strict dimensional tolerances across intensive shooting schedules. The defining technical edge of this specific configuration is its precision-cut 5/8"x24 TPI (Threads Per Inch) thread pattern boundary paired with a wide-bore .45 ACP aperture. This unique design allows operators to mount a large-bore modular suppressor, like the BANISH 45 or BANISH 46, straight onto specialized sub-caliber hosts—such as subsonic .300 AAC Blackout bolt-action pistols or custom large-bore handguns utilizing standard rifle-pitch muzzle threads—without creating a risky baffle strike environment.
The true operational highlight of this tactical hardware lies in its low-visibility surface physics and effortless maintenance dynamics. Treated with an ultra-hard, corrosion-proof Black Nitride / QPQ finish that resists aggressive carbon seizing and shrugs off harsh ultrasonic chemical solvent baths, the outer collar features crisp, permanently engraved thread spec labels. Functioning as the primary sliding interface inside your Nielsen booster device, the piston moves in a smooth, spring-assisted linear stroke to decouple the physical mass of the suppressor from the barrel's short-recoil axis. Weighing a nimble 1.85 ounces, this American-made milestone delivers absolute mechanical authority for operators handling specialized multi-caliber firearms arrays.
Includes: (1) BANISH Suppressors Threaded Suppressor Piston (.45 ACP Aperture Size / 5/8x24 Thread Pitch, Black Steel Construction), and Factory Presentation Cardboard Retail Sleeve.
*Booster Assembly Cleaning & Lubrication Guidance: Because this 5/8x24 piston is often deployed alongside subsonic rifle calibers like .300 Blackout, it can experience increased carbon soot accumulation inside the booster housing. To maintain a smooth, hydraulic mechanical action, dismantle the rear cap assembly after your training string, clean the piston walls with a brass wire brush, and apply a premium high-temperature anti-seize grease directly along the external alignment splines.
Key Features
- Specialized 5/8x24 Thread Pitch: Industry-standard rifle thread profile allows large-bore pistol suppressors to anchor seamlessly onto specialized subsonic rifle or heavy-profile pistol barrels.
- Premium Heat-Treated Steel: Weapons-grade steel core easily shrugs off devastating muzzle blast erosion, extreme pressures, and thread stripping across heavy duty cycles.
- Wide-Bore .45 ACP Aperture: Generous internal bore clearance safely channels any sub-caliber projectile up into the main suppressor core, eliminating alignment margin errors.
- Nielsen Booster Device Integration: Relieves the host firearm's barrel from structural weight traps during unlock cycles, preventing frustrating short-cycling or stovepipe failures.
- Ultra-Hard Black Nitride Finish: Low-friction, corrosion-proof liquid nitride treatment hardens outer steel surfaces to minimize internal scuffing and ease carbon cleanup loops.
- Laser-Engraved Thread Labeling: Perimeter collar features permanently etched thread dimensions and rotation directions for foolproof sorting inside a busy field range bag.
