The whole point of JK Armament's mission configurable design is that you're never locked into one setup, and the front cap is where a lot of that flexibility lives. This 22 cal Compensator End Cap (JK105LTCEC22) is built for the JK 105 LT Micro Compensator and also threads onto select JK 105 series suppressors, so a single cap can pull duty across a couple of different hosts. The compensator-style porting vents gas to help tame muzzle rise, and it gives the front of your setup a distinct look compared to the flat and flash hider cap options in the LT lineup.
Here's the part a lot of folks overlook: matching the end cap bore to the caliber you're shooting makes a real difference. JK's 105 series caps come in multiple bore sizes, and running this 22 cal cap on a rimfire or 5.7 host instead of a 9mm cap tightens up the exit hole, which keeps more gas working inside the device where it belongs. If you picked up a 105 CCX or LT Micro Comp in a 9mm configuration and want to run it on your 22s, this is the cap that makes that swap worthwhile.
JK Armament is a veteran owned Idaho company, and their machining reputation shows up even in small parts like this one. The cap wears a black hard anodized finish that matches the rest of the 105 series, threads on and off by hand for cleaning or reconfiguring, and holds up to regular swaps without chewing up the threads.
If you own more than one JK 105 series device, keeping a 22 cal compensator cap in the range bag just makes sense. It takes seconds to install, requires no fitting or modification, and lets you get the most out of whatever rimfire host you're running that day.
It's designed for the JK 105 LT Micro Compensator and also works with select JK 105 series suppressors. It installs as a direct replacement for the factory front cap, so there's no fitting or modification needed. If you own multiple 105 series devices, one cap can move between them.
Bore size matters. A cap sized closer to the bullet diameter captures and controls more combustion gas, which improves performance on rimfire and other 22 caliber hosts. If your 105 series device came configured for 9mm, this cap is the right move when you switch over to a 22 host.
The compensator version uses porting to vent gas and help control muzzle rise, while the flash hider cap focuses on reducing visible muzzle flash. Both fit the same 105 LT platform, so it really comes down to which trait you value more on your setup. Plenty of owners keep both and swap depending on the host.
For most swaps it threads on and off by hand, though JK does offer a 105 series wrench if a cap gets stubborn after carbon buildup. Snug it up properly before shooting and check it periodically, just like any muzzle-end component.
