SIG SAUER is proud to introduce the new SLX and SLH series of suppressors. 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.

Charlie H –
This is a very expensive flow threw can for 5.56 and on top of it, it is HEAVY at over 19 oz of weight. That is more than 1 pound for a modern 3D-printed suppressor. The MCX/Spear LT is already front-heavy and even on a SBR, slapping this on there made it feel more cumbersome. Other than the high price and heavy weight, it works surprisingly well.
Note that this QD version requires SIG’s muzzle device – they include one, but if you have a Spear LT it should already have one on its barrel pre-installed.
