At KYGUNCO, we're always on the lookout for top-of-the-line products that provide our customers with the best shooting experience. That's why we're excited to introduce KAC's Pressure Reduction Technology (PRT) Signature Reduction Device line. These suppressors are the perfect blend of durability, performance, and innovative design.

With the PRT technology, these suppressors are specifically engineered to release the majority of the pressure contained in the device and bore before the operating system begins extraction. This means that you'll experience significantly reduced negative effects of suppressor integration, as well as less felt recoil compared to traditional suppressors that offer the same level of sound reduction.

Not only that, the PRT design also tackles muzzle flash, particularly first-round flash. You can expect minimized muzzle flash and a more enjoyable shooting experience. And when it comes to mounting, the Quick Disconnect (QDC) method ensures reduced carbon-lock, along with minimal but repeatable point of impact shift when transitioning between suppressed and unsuppressed configurations.

Maintenance is made easy with the PRT devices. You can clean them using commonly used bore solvents or even opt for ultrasonic tank cleaning with a quick water rinse.

The Knight's Armament 5.56 QDC/MCQ-PRT connects to all 5.56 QDC Muzzle Devices.

Shop with KYGUNCO for the best selection, competitive pricing, and exceptional customer service. Experience the difference that comes with buying from a trusted outdoor retailer with over 20 years of experience in the industry
