Description
The whole point of the Banish 20 is running it on the shotgun you already carry, and this adapter is what makes that work on a Browning Invector-Plus 20 gauge. It installs the same way a choke tube does, spinning right into the factory choke threads at the muzzle. The suppressor then mounts onto the adapter for a solid, repeatable connection. Nothing about your barrel gets altered, and if you ever want to run the gun bare again, back the adapter out and screw your regular chokes back in.
Why the Banish 20 Uses Choke-Mount Adapters
Instead of forcing you into a threaded barrel or a dedicated suppressor gun, Banish built the 20 around swappable choke-system mounts. That was a smart call. Invector-Plus threads live on a huge number of Browning and Winchester 20 gauges, from Citori over-unders to A5s, Maximus pumps, and Gold autoloaders, so odds are good the bird gun in your safe is already set up for this. And since the mounts are sold individually, one suppressor can bounce between shotguns with different choke systems just by picking up the right adapter for each barrel.
You Don't Lose Your Chokes
A fair question people ask is what happens to choke constriction once the adapter takes the place of your tube. The answer is the chokes move to the front of the can. The Banish 20 ships with Improved Cylinder, Modified, and Full tubes that thread into the suppressor itself, so you still pattern and tighten your spread the way you always have, just with a much softer report behind it.
Fit and Field Use with the Banish 20 Adapter
Installation takes about as long as swapping a choke before a hunt. Snug it up properly, mount the can, and check tightness the same way you would any muzzle device through a day of shooting. It's a simple piece of hardware, but it's the one that turns a standard Invector-Plus barrel into a suppressor host without a single trip to the gunsmith.

Frequently Asked Questions
Will this Banish 20 adapter fit my Browning 20 gauge?
If your barrel uses Invector-Plus choke threads in 20 gauge, this is the correct adapter. That covers a wide range of Browning shotguns as well as Winchester models built on the same choke system. Just confirm your barrel says Invector-Plus rather than standard Invector or Invector DS, since those use different threads and have their own dedicated adapters.
Do I need a gunsmith to install it?
No. The adapter threads into your barrel's choke tube threads the same way a standard choke does, and the Banish 20 then mounts onto the adapter. It's a hand installation that takes a couple of minutes, and nothing about the barrel is permanently modified.
Can I still shoot with a choke once the adapter is installed?
Yes, the choke just moves to the front of the suppressor instead of the barrel. The Banish 20 comes with Improved Cylinder, Modified, and Full tubes that thread directly into the can, so you keep full control over your patterns. Your favorite extended aftermarket chokes won't carry over, but the included set covers most hunting situations.
Does this adapter work with the Banish 12 or other suppressors?
No, this one is purpose-built to pair the Banish 20 with Invector-Plus 20 gauge barrels. The Banish 12 uses its own line of 12 gauge mounts, and Banish sells separate adapters for other choke systems like Invector DS and Remington threads. Match the adapter to both your suppressor and your barrel's choke pattern and you're set.
