5.56 NATO Clutch-Lok QD Inconel 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.
