We now offer a shotgun barrel threading service to add internal (Rem Choke) or external (7/8x32tpi) threads. Please watch the videos below for additional threading information.


The JK Armament 195 series of 12 gauge shotgun suppressors has two primary mounting options: CRMD and OBMD. CRMD stands for choke replacement muzzle device. OBMD stands for over barrel muzzle device.

If you are looking to suppress a shotgun that uses interchangeable chokes, go with a CRMD. Your existing chokes screw into the inside of your barrel, and this is how you control your shot pattern constriction level. Our CRMD will simply screw into your barrel in place of your choke tube and will then act as a quick attach muzzle device onto which your JK 195 suppressor attaches.

If you own a shotgun that isn’t threaded for choke tubes, which is the majority of tactical and self-defense-style shotguns, we recommend using our OBMD. This likely means you’ll have to get your shotgun’s barrel threaded, which is a service we offer here at JK. An OBMD installed on external threads offers a shorter mounting system compared to the CRMD, and it’s also more robust.

In either case, since it’s the Choke Cap at the very muzzle end of the JK 195 suppressor that controls shot pattern constriction, you’ll have full, rapidly swappable choke levels available by simply exchanging Choke Caps. Your CRMD or OBMD can remain “permanently” installed on your barrel.

*Threading service only, no choke tube will be provided or installed.

*Please note, after threading, barrels will need to be refinished (cerakote, blueing, etc) or there will be visible marks from the machining process.

* Expect a 3-6 week turnaround time for custom shop services.

*The NFA defines a short-barreled shotgun as any shotgun with a barrel less than 18 inches long. This includes both shotguns that are made to have a short barrel or those that have been modified to reduce the barrel length.

With this build I can suppress every .30 caliber and smaller rifle and every 9mm and smaller pistol in my collection. Whether I’m running my AR-15 or AR-10 hard – even full-auto – or I’m on a spot-and-stalk hunt with a lightweight bolt-action rifle, or I’m plinking or varmint hunting with a rimfire rifle, or I’m shooting pistols and pistol caliber carbines in 9mm or smaller, this one suppressor can be configured so it’s ideally suited for each and every one of those things and more.

Heck, if I also owned a 45 ACP pistol and/or a 458 SOCOM rifle or a .45 cal lever action I could add 5x .45 cal LT and/or PRO Pistol baffles and have those guns covered, too!

It’s also a Mission Configurable 9mm pistol and PCC suppressor that’s capable of being run in a full configuration for training on the shooting range and a short configuration for concealed carry. It’s so lightweight that it doesn’t need a booster!
