Capitol Armory is licensed in all suppressor-friendly states. Form 4 or 4473? Read 4473 vs. Form 4 Suppressors. Your choice during checkout. See how suppressors direct to your door works or choose to send to your local dealer.

Under ATF's October 9 policy, you can buy a suppressor on a 4473 in some states. We still recommend a Form 4: it stays compliant if the policy changes, and ATF approvals come back in days.

KNIGHT'S ARMAMENT 5.56 QDC/CRS-PRT

The KAC 5.56 QDC/CRS-PRT is a 5.56mm rifle suppressor that mounts to Knight's Armament QDC (Quick Disconnect Coupling) muzzle devices. CRS stands for Combat Rifle Suppressor, which is designed as a balance between suppression and a small footprint. PRT stands for Pressure Reduction Technology, which is designed to release pressure in the suppressor and bore before the rifle begins extraction.

 

USED CONDITION

This suppressor has been fired. The flat dark earth exterior looks brand new and shows very minimal handling. Carbon fouling is visible through the vented end cap, and there is carbon buildup inside. Estimated round count is 500 to 1,000 rounds. This sale is for the suppressor only. Images are not of this specific suppressor and may be generic images.
