The KAC NT4 PRG Suppressor with 28dB sound reduction rating; sintered Inconel housing; black color; full auto caliber rating; 6.75” overall length; and 19.75 oz weight.

The QDSS NT4 PRG offers the aesthetics of the original NT4 but with modern sintered manufacturing and pressure reduction technology (PRT) which vents pressure away from the user.

This new PRG system Signature Reduction Device line makes use of the blast pulse of the contained pressure to mechanically remove the combustible environment from the suppressor, almost entirely eliminating first round flash.

While the first suppressors, and many to this day, utilize a threaded barrel-to-device connection, Knight’s developed and fielded a much faster and easier system of connection which evolved into the Gate Latch. First fielded on the M4QDSS, this system has now been made available on the NT4 and M110/SR-25 suppressors, and it makes quick attachment and detachment possible without sacrificing a secure fit.
