BANISH® Suppressors 4787 Replacement Piston – .45 ACP for BANISH 45/46 – Silver – 1/2X28 Thread Pitch – 100000310931
The BANISH® Suppressors 4787 Interchangable Neo-Booster Piston (100000310931) is an essential, premium-grade NFA firearm accessory masterfully engineered to unlock ultimate multi-host versatility for your premier modular suppressor setup. While modular silencers offer incredible caliber cross-compatibility on paper, utilizing them across a diverse fleet of handguns frequently becomes a logistical headache due to varying barrel thread patterns and the strict mechanical requirements of modern semi-automatic tilting barrel designs—which often lock up or fail to cycle when weighed down by a direct-thread muzzle device. The BANISH conversion piston completely shatters those operational limitations. This specialized direct-thread interface hardware (810171224156) drops straight into your existing booster assembly, ensuring flawless inertial tracking and flawless hostage extraction.
The structural foundation of this precision component is CNC-machined from a premium block of solid, heat-treated steel. Chemistry-optimized by Silencer Central to withstand continuous spikes of intense thermal energy and abrasive high-velocity muzzle gasses, it maintains rigorous dimensional stability over thousands of rapid-fire strings. The defining technical edge of this specific configuration is its precision-cut 1/2"x28 TPI (Threads Per Inch) thread pattern boundary paired with a .45 ACP wide-bore pass-through port. This specialized layout allows operators to safely mount large-bore modular suppressors, like the BANISH 45 or BANISH 46, straight onto 9mm or smaller sub-caliber pistol hosts that use traditional American slimline muzzle threads, effortlessly redirecting gas vectors without introducing a risky baffle strike environment.
The true operational highlight of this tactical adapter lies in its user-friendly tracking details and frictionless cycling dynamics. Finished in a highly durable, corrosion-resistant Silver finish that handles cleaning solvents and ultrasonic carbon-removal routines with ease, the outer collar features crisp, factory-engraved labels mapping out the exact thread diameter, pitch, and rotational direction. Serving as the primary contact slider inside your Neilson device booster housing, the piston moves in a smooth, spring-assisted linear motion to decouple the physical mass of the suppressor from the barrel's short-recoil axis. Weighing a featherlight 1.76 ounces, this American-made milestone delivers absolute mechanical authority for shooters navigating comprehensive multi-gun operations.

*Nielsen Device Booster Maintenance Guidance: To keep your spring-assisted booster system cycling with perfect fluid momentum and prevent carbon seizing, occasionally clear out internal debris. After intensive range days, unscrew your suppressor's rear cap, extract the piston and booster spring, and scrub the outer silver bearing walls with a soft brass brush. Apply a liberal film of high-temperature lithium or anti-seize grease directly along the piston’s external alignment splines before reassembly.
Key Features
- Optimized 1/2x28 Thread Pitch: Provides an industry-standard direct-thread attachment path to safely anchor large-bore suppressors onto sub-caliber hosts like standard 9mm handguns.
- Premium Heat-Treated Steel: High-tensile weapons-grade steel matrix easily shrugs off devastating blast erosion, high pressure, and thread stripping across aggressive 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.
- Scratch-Resistant Silver Finish: Industrial matte silver finish makes tracking soot and carbon deposits simple while providing maximum surface slickness inside the booster bore.
- Laser-Engraved Thread Labeling: Perimeter collar features permanently etched thread dimensions and rotation directions for foolproof sorting inside a busy field range bag.
