HW50/57/99 tuning pistons

Original HW50/57/99 piston from Weihrauch, rear-mounted with a ring of highly lubricating, bronze-coated PTFE, also known as Teflon. The bronze coating makes the PTFE more resistant to deformation and wear. The piston bearing prevents metal-on-metal contact, guides it more precisely, and reduces the shooting noise.

In the Premium version, the weight is reduced by approximately 15% from 223g to 189g for improved recoil. The V0 is usually slightly lower due to the lighter weight. This can be readjusted with Jonasscheiben, for example.
