The KAC 7.62 QDC/CRS-PRG suppressor is a precision-engineered solution for large frame, medium-caliber rifles, such as the SR25 / AR10 platform rifles. Optimized for flash reduction, back pressure management, and long-term durability, this suppressor features Knight’s Armament’s innovative Pressure Reduction Technology (PRT) and advanced baffle design (PRG). The result is a suppressor that not only minimizes gas blowback but also significantly reduces first-round flash and acoustic signature, making it a top choice for precisions shooters seeking excellent suppressor technology. 

FEATURES & BENEFITS 

The 7.62 QDC/CRS-PRG is built to withstand the rigors of high-volume fire, ensuring consistent performance across a variety of platforms. The PRT system minimizes back pressure, helping maintain bolt carrier velocity and rate-of-fire near unsuppressed levels, while pushing noxious gases away from the user. The PRG baffle design further reduces flash and sound, with a particular focus on eliminating the first-round pop. The suppressor is compatible with all KAC 7.62mm QDC muzzle devices, offering secure and reliable attachment.
