The CGS Suppressors Nautilus Piston M16x1 LH Black Nitride 17-4 Stainless Steel is a purpose-built suppressor piston designed to securely mount a Nautilus silencer to barrels threaded in M16x1 left-hand. Precision machined from durable 17-4 stainless steel and finished in black nitride, it offers excellent strength, corrosion resistance, and a smooth interface with the host firearm and suppressor.

This self-aligning piston helps ensure the silencer centers correctly on the bore, reducing the risk of baffle strikes and promoting consistent accuracy. Its positive spoke lock interface provides a solid, repeatable lockup to the suppressor housing, making it well suited for dedicated range use, training, and general shooting with compatible recoil-operated pistols. Shooters who value reliable suppressed performance will appreciate CGS Suppressors’ attention to engineering detail and build quality in this compact 2-inch, 1.30-ounce component.
