Product Description The CGS Suppressors Piston (CGSKRK58X24PISTBK) is a precision-engineered suppressor mounting component designed specifically for the Kraken, MOD9, and Nautilus series silencers. Machined from premium 17-4 precipitation-hardening stainless steel and treated with a durable Black Nitride finish, this piston delivers exceptional corrosion resistance, surface hardness, and long-term reliability under the intense heat and pressure of repeated firing. Its 5/8"-24 TPI thread pattern makes it broadly compatible with a wide range of firearms including .30 caliber rifles and pistol-caliber carbines. The piston features an innovative self-aligning system that ensures perfect bore concentricity every time the suppressor is attached, dramatically reducing the risk of dangerous baffle strikes. A positive spoke lock mechanism creates a very secure and stable interface with the suppressor housing, preventing any loosening under sustained firing. Compact at 2 inches in length and weighing only 1.30 ounces, this piston adds minimal bulk to your setup while maximizing suppressor performance and shooter safety. Product Highlights Premium 17-4 Stainless Steel Construction: Offers superior hardness, wear resistance, and rust/oxidation resistance, ensuring dimensional integrity over thousands of rounds. Black Nitride Finish: Thermochemical surface treatment that increases surface hardness, enhances corrosion resistance, reduces friction, and provides a matte black appearance that minimizes glare. Self-Aligning System: Intelligently compensates for minor manufacturing tolerances, guiding the suppressor into optimal bore alignment and reducing the risk of baffle strikes. Positive Spoke Lock to Housing: A robust locking mechanism that keeps the piston firmly and securely engaged with the suppressor housing under repeated firing stress. Lightweight and Compact Design: At just 1.30 oz and 2 inches in length, it minimizes added weight and preserves your firearm&';s balance for quick target acquisition.
