JK Armament 105 RFX 22K Rimfire Suppressor, 1/2x28, Black The JK Armament 105 RFX 22K is a lightweight, modular rimfire suppressor for 22 LR and other approved small-caliber cartridges. It lets the shooter choose a suitable balance of compact handling and sound reduction for a compatible pistol or rifle. The Black suppressor includes a 1/2x28 direct-thread mount. Its slim aluminum construction and accessible baffle system make it a practical choice for plinking, rimfire practice, and small-caliber range use.

Modular Length for Different Rimfire Hosts The 105 RFX 22K uses a modular baffle arrangement so the complete suppressor can be configured around the firearm and the desired balance of size, weight, and suppression. A shorter assembly puts less length at the muzzle; more baffles provide a larger suppression assembly. The important benefit is the ability to choose a suitable configuration within the approved system rather than accept one fixed overall size. Aluminum Construction and a Slim Profile 7075 billet aluminum keeps the suppressor light, while the 1.05-inch diameter maintains a slim profile on a compatible rimfire pistol or rifle. Low muzzle weight can be particularly useful on a compact pistol or a rifle carried between shooting positions. The aluminum components require cleaning methods appropriate to the material; aggressive processes intended for steel parts should not be assumed suitable. Rimfire Coverage Beyond 22 LR The 105 RFX 22K supports 22 LR, 22 WMR, 17 HMR, 17 Mach 2, 17 WSM, 22 Hornet, and 5.7x28mm. That coverage makes it useful for an owner with several compatible small-caliber firearms. The caliber list is specific: a .22-caliber designation does not imply approval for high-pressure .223 Remington or 5.56 NATO rifle ammunition. Direct-Thread Mounting and Service Access The included 1/2x28 mount connects to a matching threaded barrel, and the modular construction provides access for routine cleaning. Rimfire ammunition can leave substantial fouling, so user-serviceable components are a practical ownership feature. Match the barrel thread, muzzle geometry, and firearm requirements before use; a thread match alone is not complete fitment confirmation. Included Components The suppressor includes a 1/2x28 LT thread mount, a 1.3-inch LT tube, 7 LT rimfire baffles, and a flash-reducing end cap. The included components provide the modular range without requiring a separate quick-attach muzzle device.
