KNIGHT'S ARMAMENT QDSS NT-4 PRG 5.56MM NATO RIFLE SUPPRESSOR
 
Recent advancements in suppressor design and manufacturing have enabled KAC to update the venerable Quick Detach Sound Suppressor (QDSS) NT4 suppressor with both Pressure Reduction Technology (PRT) and KAC’s patented Purge (PRG) flash reduction. 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 operator’s 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 5.56mm M4QD muzzle devices, the QDSS NT4 PRG is recommended for those that must maintain the M4QD mount but desire cutting edge suppressor performance.
 
SPECS
  • Overall Length: 6.4”
  • Addition to bare muzzle: 5.9”
  • Weight: 19.8 oz

Frequently Asked Questions

Are these brass cases and reloading components factory-new or once-fired? +

We stock both premium factory-new components and high-quality once-fired brass. Please check the specific product listing title and description carefully; once-fired brass is fully inspected, but we always recommend resizing and inspecting prior to priming and powder charging.

Will this case trimmer gauge or die set work with my progressive press setup? +

Our standard reloading dies and case length trimmer accessories utilize industry-standard threads (typically 7/8"-14) compatible with major single-stage, turret, and progressive presses like RCBS, Hornady, Lee Precision, and Dillon. Caliber-specific trim gauges must match your exact brass caliber.

Do you enforce shipping restrictions on powder, primers, or live ammunition? +

Yes. Non-hazardous reloading equipment (dies, case length trimmers, gauges, and unprimed brass) ships via standard ground carriers with no extra fees. Any orders containing smokeless powders or primers will incur standard federal HazMat handling fees and cannot be shipped via air transportation.

How can I track my shipment to ensure delivery safety? +

Precision reloading gear is valuable, so all orders are shipped with tracking enabled. As soon as your package is dispatched from our inventory warehouse, a tracking number will be emailed to you. You can monitor your shipment directly on our Track Order page using your unique Order ID.

Can I return precision measuring tools or die components if they don’t fit? +

We accept returns on unused, unaltered tools, case preparation equipment, and unopened component boxes within 30 days of item delivery. Due to safety and strict quality control on the reloading bench, we absolutely cannot accept returns on opened packs of primers, smokeless powder, or processed brass casings.
