Walther CP2 Manual

I just want to add a tip regarding the blast valve o-ring for CP2, that seems impossible to obtain. The spec for this o-ring is ø4x2 PU93, and unfortunately you can't get this o-ring through Walther anymore. What you can do, however, is to buy the FWB part number 4.9.0008 (O-Ring 4,0 x 2,0). This is a ø4x2mm 90 shore o-ring that does the job perfectly. I'm not sure what material this o-ring is, but it works well with Co2. 🙂👍
