Stiction Lock Comp 5.56 - 1/2-28 Flash Hider for Xeno and Hub Stiction Lock Systems The Stiction Lock Comp 5.56 is a serviceable flash-hider engineered for 5.56x45mm/.223 Remington platforms. Machined from 17-4 stainless steel for durability and resistance to erosion, the device uses precision porting to reduce visible muzzle flash and improve follow-up sight picture without adding unnecessary length or weight. Threaded 1/2-28 for direct fit to common AR-pattern muzzles, the Stiction Lock Comp accepts Dead Air Xeno mounting interfaces and also mates with the Hub Stiction Lock adapter for versatile quick-attach or hub-style suppressed setups. Designed for repeatable, tool-simple installation, the sealed engagement and robust construction minimize carbon lock and preserve thread life when used with compatible Xeno adapters or Stiction Lock mounts. Verify adapter selection and visually confirm baffle alignment after installation before firing.
