Keeping Traditions Alive Since 1953

One of the smartest things JK Armament did with the 195 series was move the choke system out of the barrel and into the end cap of the suppressor itself. This Improved Cylinder Choke End Cap is a direct swap for JK 195 series 20 gauge cans, giving you a touch more pattern restriction than the cylinder bore cap most 195 suppressors ship with. That extra constriction is right in the sweet spot for a lot of real-world shotgun work, tightening birdshot to roughly a two foot spread around 20 yards instead of the wider, faster-opening pattern you get from a straight cylinder bore.
Traditional shotgun suppressors force you to live with whatever pattern the can gives you. JK's patented Choke Cap design fixes that by putting the constriction at the very end of the suppressor, so you can shape your pattern to the job at hand. Swapping caps takes seconds. There are standard wrench flats machined into the cap, 1.87 inches across, so a common wrench handles removal and installation. No proprietary tools, no fuss, and it's genuinely faster than screwing choke tubes in and out of a barrel. JK modeled the constriction levels after familiar shotgun choke names, so if you know what Improved Cylinder does out of a bare barrel, you already know what to expect here.
This cap is machined from aluminum with a hard anodized black finish that shrugs off field wear, and at .711 inches long it keeps your setup compact. Like everything JK Armament builds, it's made in the USA and backed by their lifetime guarantee.
If your 195 SGX 20 has been running the factory cylinder cap and your patterns feel a little loose on crossing clays or flushing birds, this is the natural next step up. As always, spend a little time patterning your specific gun and load with the new cap so you know exactly where your effective range sits before the season opens.
This cap is built for JK Armament's 195 series 20 gauge suppressors with aluminum bodies, like the 195 SGX 20GA. It threads on in place of the cylinder bore cap that ships on the suppressor from the factory. Make sure you grab the 20 gauge version, since JK also makes these caps in 12 gauge.
With the Improved Cylinder cap, birdshot spreads to roughly a two foot diameter at around 20 yards, versus the faster-opening spread of a cylinder bore. That makes it a solid pick for clays and bird hunting at moderate ranges. JK recommends patterning your specific gun and load so you know exactly what your setup does in the field.
No, and that's one of the best parts of the system. Each cap has standard wrench flats measuring 1.87 inches across, so a common wrench gets the job done in seconds. It's quicker and easier than changing traditional choke tubes in a barrel.
JK's lead-only restriction applies specifically to their Full choke cap. The Improved Cylinder constriction is a common choice for steel shot in traditional chokes as well. That said, always pattern your specific load first, and check your suppressor's ammo ratings before running anything through the can.
