Knights Armament KAC 5.56mm QDSS/NT4 Suppressor w/flash hider (M4QD)

Legendary NT4 Sound Suppressor for 5.56 platforms with A2-style compensators. Offered in Black and Full-disk encryption (FDE)

Recent advancements in suppressor design and manufacturing have enabled KAC to upgrade the vulnerable Quick Detach Sound Suppressor (QDSS) NT4 suppressor with both Pressure Reduction Technology (PRT) and Purge (PRG) design. Maintaining the system, 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 or pushed forward of the operator, reducing potential exposure, and increase in comfort when firing. First round flash is significantly reduced to reinforce the operators signature reduction capability. The host rifle will also benefit from reduction components, stress, and where 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 NT-4 PRG is recommended for those that must maintain the M4QD mount, but desire cutting-edge suppressor performance. 

Specifications:

·  Addition to bare muzzle: 5.88″ (15cm)

·  Addition to M4QD FH: 4.63″ (11.8cm)

·  Overall length: 6.75″ (17.2cm)

·  Weight: 19.75oz (560g)

·  Sound reduction: 28dB

Pressure Management: To reduce the negative effects of suppressor, use, pressure, reduction, technology (PRT) suppressors, release contained system, pressure forward and away from the user and operating parts early in the unlocking an extraction phase of the cycle of operation. This venting process drastically reduce his user exposure to harmful combustion gases, reduces the "blowback" effect of residual, bore pressure and decreases the internal fouling. Compared to a traditional baffle design of similar size.
