HW77/97 tuning pistons
Original HW77/97 piston from Weihrauch with 6 CNC milled longitudinal slots for weight optimization. The original weight of approx. 260g has been reduced to approx. 218g. This corresponds to the weight of the earlier 25mm pistons.
The weight reduction leads to less rebound and thus to improved shooting behavior. Installation is easy, but the V0 must be checked afterwards.
In the basic version with the original Weihrauch piston seal.
The Premium Version I also contains a self-lubricating 26mm piston seal and a stainless steel piston inner sleeve.
The Premium Version II contains a self-lubricating 26mm short stroke piston seal and a stainless steel piston inner sleeve.
- significant weight loss
- improves the shooting behavior of your Weihrauch Preller
- replaces the Weihrauch standard flask
- easy installation/replacement
