Fits Weihrauch HW45 Star series only (Black star, Silver star, etc), but not the standard version with shell grips. Please, contact me for the latter, I can get you one.
Made of strong plastic, 3D printed. This material allows further sanding and surface treatment.
The lightweight but sturdy stock is optional. £20 plus £4 postage. It is attached to the original grip by longer bolts (M5x55 and M5x65, supplied). The Weihrauch HW45 airgun is very accurate, so it is worth having a stock for even better results.
Very easy to fit.
