Description
This is the piece that connects your Banish 20 suppressor to a 20 gauge shotgun running Rem Choke style threads, like the Remington 870. It threads into your barrel where a standard choke tube would sit, giving the suppressor a solid, repeatable mounting point without changing how the gun handles. If you already own the Banish 20 and want to run it on a Rem Choke barrel, this is the adapter that makes it happen.
What Sets the Banish 20 Rem Choke Adapter Apart
Banish machines this mount from 17-4 PH stainless steel, which is about as tough as it gets for a part that lives at the business end of a shotgun. It gets finished with a black nitride coating, so it shrugs off corrosion whether you're hunting a saltwater blind, wading flooded timber, or just leaving it in a damp truck bed between trips. The whole point is durability and a clean, snug interface that keeps everything lined up shot after shot.
Picking the Right Mount for Your Shotgun
Here's the thing worth knowing up front: the Banish 20 uses shotgun-specific mounts, and this one is cut for the Rem Choke thread pattern. Banish also offers mounts for Benelli Crio Plus, Benelli Mobil, Beretta Optima HP, Browning Invector Plus, and Browning Invector DS setups. Grabbing an extra adapter or two is how a lot of folks run one suppressor across several shotguns, so if you swap between guns during the season, this is the easy way to do it. Just match the adapter to your barrel's choke threads and you're set.
Built for the Banish 20 System
The Banish 20 itself is a titanium 20 gauge suppressor built around upland and sub-gauge hunting, keeping the sight picture clear from bead to bird. This adapter is the foundation of that system. Once it's threaded in, the suppressor mounts up clean and the interchangeable chokes do their job on top. It's a simple part with an important job, and Banish backs its gear with a lifetime warranty against manufacturing defects.

Frequently Asked Questions
What shotguns does the Banish 20 Rem Choke adapter fit?
It's built for 20 gauge shotguns with Rem Choke style threads, which covers the popular Remington 870 platform and other barrels cut for that pattern. If your barrel takes standard Rem Choke tubes, this adapter will thread right in. When you're unsure of your thread pattern, check your existing choke tubes or your barrel markings before ordering.
Do I need this adapter if I already own the Banish 20 suppressor?
The Banish 20 uses shotgun-specific mounts, so you need the adapter that matches your barrel's choke threads. This one is the Rem Choke version. If you plan to run the suppressor on a different shotgun with a different choke system, you'd want the matching mount for that gun instead.
Can I use one adapter across multiple shotguns?
This particular adapter works with any 20 gauge shotgun sharing the Rem Choke thread pattern, so it can move between those guns. If you also own shotguns with Benelli, Beretta, or Browning choke threads, Banish sells separate mounts for those. Picking up extra adapters is how a lot of owners run a single Banish 20 across their whole shotgun rack.
What is the Banish 20 adapter made of and will it rust?
It's machined from 17-4 PH stainless steel and finished with a black nitride coating for corrosion resistance. That combination holds up well in wet, harsh conditions like duck blinds and flooded timber. A quick wipe-down after damp hunts keeps it looking and performing its best.
