HW77/97 Tuning Piston

Original HW77/97 piston from Weihrauch with 6 CNC-milled longitudinal slots for weight optimization. The original weight of approximately 260 g has been reduced to approximately 218 g. This corresponds to the weight of the previously used 25 mm pistons.

The weight reduction results in less recoil and therefore improved shooting performance. Installation is simple, but the muzzle velocity (V0) must be checked afterwards.

In the basic version with the original Weihrauch piston seal.
The premium version I additionally includes a self-lubricating 26 mm piston seal and a stainless steel piston inner sleeve.

The Premium Variant II includes a self-lubricating 26 mm short stroke piston seal and a stainless steel piston inner sleeve.

  • significant weight loss
  • improves shooting performance
  • replaces the standard incense piston
  • easy installation/replacement

Scope of delivery:
Basic: Tuning piston + Weihrauch gasket

Premium I: Tuning piston + AirJoe seal + Weihrauch seal + inner sleeve
Premium II: Tuning piston + short stroke gasket + Weihrauch gasket + inner sleeve
