Things I liked: I ordered all new stock screws for a 1983 Beeman R1. Perfect fit, all new threads hold well. Current screws still are perfect fit.
Things I would have changed: Weihrauch must not care to much about the US market. I received all the screws a few at a time, the last arrived 8 months after ordered. Pyramydair had to wait on the parts. I wonder what happens if you really need a part.
What others should know: German Beeman quality is second to none
