Design and Function

Like the LTX and LTX Mini, the LTX-K is based on the high-flow principle. The internal flow channels direct the propellant gases specifically forward and away from the shooter. This significantly reduces backpressure, puts less strain on the firearm, and ensures the shooter inhales fewer hot and toxic gases.

The Inconel 718 material provides low weight combined with high strength and temperature resistance. Muzzle flash suppression is strong and largely spark-free—making it suitable for use in low-light conditions.

HUB Compatibility

The silencer features the standardized HUB thread 1.375″-24 UNS. A compatible HUB adapter is required separately and extends the silencer.
