LMT Defense IonK Features The LMT Defense IonK is engineered around a Stainless Steel and Inconel construction two materials chosen specifically for their ability to withstand the heat and pressure of full-auto rated rimfire fire. Inconel is a nickel based superalloy commonly used in high heat applications and pairing it with stainless steel gives the IonK the durability to handle extended strings of fire without degrading. The suppressor s 1/2x28 thread pattern is the most common rimfire and 5.56 pistol thread pitch so it mounts directly to a wide range of threaded barrels without an adapter. Its 1.74 diameter and 4.63 overall length keep the host firearm s balance close to unsuppressed which matters for shooters running a can on a lightweight rimfire rifle or pistol. Included with the IonK is a 3-prong flash hider restrictor cap sized for 5.56 which lets the same suppressor body serve as part of a multi-caliber hearing protection setup when paired with the right mounting hardware. The Black finish resists corrosion and wear from repeated cleaning an important feature given how quickly rimfire ammunition fouls a suppressor s internals. At roughly 16 to 19 ounces the IonK adds manageable weight to the muzzle without making the host firearm front heavy. The LMT Defense IonK suits competitive rimfire shooters training facilities and hunters who want a rugged quiet rimfire setup for sale at GrabAGun.
