Wiehrauch HW110 Bipod Stud
HW110 Front Stud Screw.
A new product created by Solware Limited. This is similiar idea to the HW100 stud simply remove existing stock bolt on Wiehrauch HW110 near the front and using a slight bit of oil on thread simply replace.
You can then put a sling/bipod on without drilling into your stock. Made from hardened steel and hot blued.
