A quality suppressor piston is the backbone of a precision sound-suppression system, and the CGS Suppressors Piston M13.5x1 LH is built to handle the rigorous demands of serious shooters and hunters. This left-hand piston is machined from 17-4 stainless steel and finished in black nitride, a combination that balances durability against corrosion while maintaining the tight tolerances your suppressor needs to function reliably. Whether you're running a precision rifle or working with a left-handed platform, this piston threads at M13.5x1 and integrates into suppressor assemblies where repeatability and longevity matter.
The 17-4 stainless steel substrate is a go-to material in firearms engineering—it resists corrosion, handles thermal cycling without degrading, and maintains dimensional stability through repeated firing cycles. The black nitride surface treatment hardens the steel further and provides a clean, professional appearance. This piston is a direct component part, not a complete suppressor, and is intended for users who either assemble their own suppressor systems or need a replacement piston for an existing CGS suppressor platform.
If you're maintaining a suppressor, upgrading a piston assembly, or building a custom sound-reduction system, this CGS piston delivers the precision fit and material quality you'd expect from a recognized suppressor manufacturer. Verify that the M13.5x1 left-hand thread pitch and geometry match your specific application or suppressor model before purchase.
| Brand | CGS Suppressors |
| Thread Size | M13.5x1 |
| Hand | Left-Hand (LH) |
| Material | 17-4 Stainless Steel |
| Finish | Black Nitride |
| Model | CGSKRK135X1LHBK |
This piston is designed for CGS suppressor platforms that use the M13.5x1 left-hand thread pitch. Confirm your suppressor model accepts this thread specification before purchase.
Black nitride is a surface hardening treatment that increases wear resistance and corrosion protection while giving the steel a professional matte-black appearance. It helps the piston withstand thermal cycling and repeated use without degradation.
No—this is a left-hand (LH) piston. It is not compatible with right-hand suppressor systems. Verify your suppressor's thread direction before ordering.
This is a piston component only, not a complete suppressor assembly. It is intended for users who maintain or assemble suppressor systems and need a replacement or spare piston.
