When SIG SAUER developed the SLH suppressors, they were designed to meet the demands of the U.S. military, delivering cutting-edge performance. This suppressor features the new Clutch-LOK QD mounting system, which is easy to use, repeatable, and extremely durable. The monolithic internal multi-flow path allows gasses to exhaust at a faster rate than traditional baffles. Resulting in up to 50% less toxic fumes flowing back through the ejection port into the shooter's face. These suppressors are designed to perform with both supersonic and subsonic ammunition, producing optimal sound reduction with both.
