Jk Jk155Proec22 155 Pro Flsh Reducer End Cap 22
The JK Armament 155 Pro Flash reducer end cap in .22 caliber is a compact muzzle device designed to tame muzzle flash on rimfire rifles and firearms. If you're running a suppressor-ready .22 build or just want to reduce that bright signature downrange, this hard anodized titanium end cap threads onto your barrel to provide flash reduction without the length or complexity of a full brake. It's the kind of practical upgrade that makes sense whether you're shooting at the range, hunting small game, or keeping a low profile on the property.
Built from titanium and finished in hard anodized black, the JK155Pro is made to last. The compact profile means it won't interfere with scope mounting or add unnecessary bulk to a lightweight rimfire setup. If you're already running a JK Armament suppressor or planning a multi-part suppressor system, this end cap plays well in that ecosystem—and it's equally at home as a standalone flash reduction solution.
The .22 caliber specification makes it purpose-built for rimfire platforms, so verify your barrel thread pitch before ordering. This is the kind of straightforward, no-nonsense accessory that serious .22 shooters appreciate: it does one job, does it well, and gets out of the way.
