The KAC CRS-1 7.62mm QD Suppressor FDE (121997-FDE) is a compact, high-performance sound suppressor designed for 7.62mm NATO and .308 Winchester platforms. Manufactured by Knights Armament Company, the CRS-1 combines excellent sound and flash suppression with a quick-detach mounting system in a shorter, more maneuverable package. Finished in durable Flat Dark Earth (FDE), this suppressor offers a professional tactical appearance that matches modern FDE rifle builds. The CRS-1 is ideal for shooters who need effective suppression without adding excessive length to their firearm, making it a popular choice for precision rifles, designated marksman rifles, and tactical applications.
