KAC Knights Armament Company BLK QDSS NT4 PRG
Manufacturer: Knights Armament Company
Part Number: KM121569-BLK
Product Description: 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.
Signature Reduction: In 2017 KAC began a study to determine and address the cause of first-round flash with suppressor use. While purging the suppressor with an inner gas was successful in reducing the first round flash, it would be cumbersome for practical use. The solution was found any novel baffle matrix that uses the blast pulse of the contained pressure to mechanically remove the combustible environment from the suppressor. This patent pending design effectively reduces spectrum flash, as well as near, short-wave, and mid-wave IR "Infrared"; and eliminates the need for flash suppressant in propellants. KAC's "purge" technology does not impact system pressure or sound pressure levels, but does illuminate first round flash, as well as the audible "first round pop" found with traditional suppressors.
Durability: Advancement in simulation, analysis and manufacturing processes have also contributed to increased service life of KAC’s suppressors. Thermal energy is spread through the monolithic structure on internal paths, eliminating “hot spots” that can fail during extreme use. When tested under continuous-fire protocols, the suppressors indoor 1. 5–2 times the number of rounds fired before failure; and one failure occurs, the structural design ensures that all energy is projected down range with no lateral escape of fragments or debris.
