KAC QDSS NT4 PRG 5.562

Leveraging advancements in manufacturing technology and advanced simulation, KAC has further refined and advanced our suppressor offerings based on the defined needs of the professional user. The most specifically addressed points in the development of these suppressors were visual signature reduction, improved heat management, bore pressure reduction and service lifespan. The use of in-house developed modeling, simulation software and innovative internal design enabled by additive manufacturing processes achieved improvement in all attributes.

Recent advances in suppressor design and manufacturing have enabled KAC to upgrade the venerable Quick Detach Sound Suppressor (QDSS) NT4 suppressor with both Pressure Reduction Technology (PRT) and Purge (PRG) design. Maintaining the same attachment mechanism and form factor as the legacy QDSS NT4, superior pressure reduction capabilities are added without sacrificing performance or durability. Potential noxious gases from the rifle being fired are pushed forward of the operator, reducing potential exposure and increasing comfort when firing. First round flash is significantly reduced to reinforce the operators signature reduction capability. The host rifle will also benefit from reduced component stress and wear through suppressed firing by allowing the rifle to maintain carrier velocity and rate-of-fire comparable to unsuppressed fire. Compatible with existing KAC M4QD muzzle devices, the QDSS NT4 PRG is recommended for those that must maintain the M4QD mount but desire cutting edge suppressor performance.
