JK Armament RFX 22K - .22 Cal Configurable Titanium Suppressor

JK Armament RFX 22K - .22 Cal Configurable Titanium Suppressor

Offering extraordinary modularity, featherweight handling, and unmatched budget-friendly value, the JK Armament RFX™ 22K (JK 105 RFX 22K) Suppressor is engineered to be one of the smallest and lightest K-sized rimfire silencers on the market. Precision-machined from 7075 billet aircraft-grade aluminum and finished in a tough Type 3 Hard Anodize, the RFX 22K delivers high-performance sound suppression across a wide spectrum of rimfire and small-bore centerfire rounds—ranging from .22 LR and .17 HMR up through high-velocity 5.7x28mm cartridges. With a starting price point of just $325.00, it brings elite modular engineering within reach of every shooter.

Built around JK Armament’s proprietary Tone Technology, the RFX 22K refines internal sound frequencies to generate a deep, solid acoustic profile that is remarkably pleasing to the human ear. Its mission-configurable architecture features seven (7) removable rimfire baffles, allowing shooters to adjust length from an ultra-tiny 1.7 inches (1.1 oz) for maximum compactness up to a full K-length 5.1 inches (3.6 oz) for maximum sound attenuation. Rated for no minimum barrel length restrictions across all supported calibers, the RFX 22K ships complete with a 1/2"x28 TPI thread mount, a flash-reducing end cap, and JK Armament’s Unconditional Unlimited Lifetime Warranty.
