Product Summary: The HX-QD 556 Ti utlizes patented and proven Flow-Through® design that moves the gases through the unit in a helical pattern that allows for expansion and cooling as they exit out the front. The torque generated by the exiting gases keeps the suppressor snug on the mount. The HX-QD 556 Ti incorporates a new flash cap that virtually eliminates all flash. No tools are needed for installation or removal. The HX-QD 556 Ti’s Flow-Through system does not increase back pressure (blowback) like a traditonal baffle suppressor. This innovative technology produces heat at a lower rate than a traditional suppressor, and it does not increase toxic gas discharge. The HX-QD 556 Ti does not increase bolt velocity (+/- 5%). Therefore, muzzle rise and recoil are managed, and there is no increase in weapon malfunctions.
