Banish 45 Piston 5/8×24 Black – Threaded Suppressor Piston

Description

The whole point of a modular can like the Banish 45 is that one suppressor can jump between guns, and the piston is what makes that happen. This is the 5/8×24 version, machined to thread onto a barrel cut for that pitch and drop into the rear of your Banish 45 or 46. Instead of buying a dedicated suppressor for every host, you keep one can and stock the pistons that match your lineup.

Banish builds these from heat-treated steel, so they hold up to the pounding a booster assembly takes on a tilting-barrel pistol. Each piston is engraved with the thread diameter, pitch, and direction of rotation, which takes the guesswork out of grabbing the right one when you have a few in the drawer. On this model the markings call out 5/8×24, and that engraving is a nice touch when you're double-checking a fit before you thread anything on.

Where the 5/8×24 Banish Piston Fits In

Thread pitch does not always line up with caliber the way people expect, so the smart move is to confirm what your barrel is cut for before ordering. The 5/8×24 pitch shows up on plenty of pistol-caliber carbine barrels and threaded pistol setups, but factory and aftermarket barrels can differ. Check the barrel's published spec or the markings on the threaded shank, then match it to this piston.

Getting the Banish 45 Piston Running Right

On most semi-auto pistols the barrel tilts as it cycles, and the piston is the moving part inside the booster that lets everything function normally while carrying the weight of the can. Install it hand-tight into the rear of the suppressor, and a light coat of a heat-tolerant grease like white lithium keeps things smooth over a long range session. Keep it clean and it'll cycle reliably for a long time. If you already run a Banish 45 or 46, this is simply the piece that lets you take it to another host without buying a second suppressor.
