Both the SLX and SLH were developed to meet the demands of the U.S. military, and are designed to deliver cutting-edge performance. The SLX series of rifle suppressors feature the new Clutch-LOK QD mounting system which is easy to use, repeatable, and extremely durable. The internal multi-flow path within the SLX suppressors allows gasses to exhaust at a faster rate than traditional baffle-style suppressors. This results in 70-80% less toxic fumes flowing back through the ejection port into the shooter's face. The SLX series is a performance-based suppressor designed for use with supersonic ammunition and ideal for users focused on flash reduction and lower toxic fumes. The new low-tox SLX suppressors deliver a superior shooting experience, unlike any other suppressor. The internal multi-flow path of the SLX with low resistance exhausts gases at a faster rate than traditional baffles. SLX features 70-80% less PPM than traditional baffle suppressors.
