SHS Reinforced Polymer Piston w/ Full Steel 14-Tooth Rack | High-Speed Airsoft Upgrade

Engineered for relentless performance in demanding airsoft builds, this SHS OEM piston delivers unmatched durability at an exceptional value. Trusted by leading technicians globally and proven in elite custom rifles, its carbon steel teeth resist stripping even under extreme stress cycles.

We reinforce the critical rack area with specialized Fiber Reinforced Epoxy – making this the go-to solution for high-stress setups like DSG (Dual Sector Gear) systems or precision DMR platforms. Rigorously tested in over 200 installations without a single failure, it offers peace of mind where other pistons break.

The pre-lightened (“Swiss-cheesed”) body is essential for high-RPM builds. This strategic weight reduction prevents catastrophic pre-engagement – where the sector gear strikes the piston prematurely – safeguarding your piston and protecting vulnerable gear teeth from damage.

Additionally, one tooth is intentionally omitted to assist with correcting Angle of Engagement (AoE) in many gearboxes. For specific configurations, minor adjustment to the final tooth may optimize meshing further.

Why choose this upgrade?
* Unbeatable Strength: Full steel teeth + polymer body reinforced with epoxy.
* High-Speed Ready: Pre-lightened design prevents pre-engagement.
* Proven Reliability: Zero failures in 200+ high-stress installations.
* AoE Optimization: Missing tooth aids correct gear engagement.
* Elite Performance: The choice of top airsoft techs worldwide.

Optimize your AEG’s reliability and speed for intense airsoft skirmishes or competitive events. This SHS piston is the robust foundation your high-performance airsoft rifle demands.
