2x V-Mach piston spring for Weihrauch HW30 blanks DIY

2 V-Mach Mainsprings for Weihrauch HW30 and HW30S

One of the highest quality and most durable mainsprings on the market. Made from Japanese valve spring steel, specially adapted for the Weihrauch HW30(S). The inner diameter is 12.6 mm, making it suitable for the white Weihrauch spring guide with 11.9 mm.

Double set for tuners as a blank with 25 coils for shortening and fitting to your exact HW30. The difference to our other HW30 spring is the thicker wire gauge of 3.0 instead of 2.6 mm.
This spring is "oversprung", i.e. too many coils for the short system of the HW30. We achieve the highest performance with approx. 20-22 coils.

• for HW30(S)
• 25 coils
• wire gauge 3.0 mm
• for shortening and individual adaptation
• only for tuners with knowledge of spring processing
