LMT DEFENSE ION K .22 CALIBER RIFLE SUPPRESSOR KIT W/5.56

The LMT Defense ION K .22 Caliber Rifle Suppressor Kit with 5.56 Compatibility is a compact, mission-focused suppressor designed to deliver exceptional sound suppression, reliability, and durability across a variety of .22 caliber rifle platforms. Currently fielded by military end users in active conflict environments, the ION K incorporates LMT Defense's patented reduced-backpressure technology, utilizing advanced alternating baffle geometries and multiple gas-flow paths to control blowback without sacrificing suppression performance. This innovative design promotes more consistent cycling, improves reliability on both semi-automatic and full-automatic firearms, reduces gas exposure to the shooter, and preserves the natural handling characteristics of the host weapon. An obstruction-free blast chamber further enhances pressure management, providing predictable suppression performance, improved flash reduction, and dependable operation across compatible cartridges including .17 HMR, .222 Remington, .223 Remington, and 5.56 NATO.

Constructed from a rugged combination of Inconel and 17-4 stainless steel and protected by a durable C-192 Armor Black finish, the ION K offers industry-leading strength while maintaining a compact, lightweight profile. Its precision-welded baffle stack architecture ensures superior alignment, repeatable accuracy, and minimal point-of-impact shift, making it suitable for both precision shooting and hard-use duty applications. The integrated taper lock gas seal helps reduce sound, flash, and blowback while minimizing the potential for carbon lock during extended firing schedules. Compatible with HUB and Xeno mounting systems, fully rated for belt-fed, semi-auto, and full-auto use, and backed by extensive military-standard testing, the ION K delivers outstanding durability with a service life exceeding 30,000 rounds under varied firing conditions. Proudly made in the USA and ready for immediate use out of the box, it provides shooters with a versatile, high-performance suppressor solution engineered for long-term reliability and consistent performance.
