Sounds like you guys know a lot more about this than I do, so can I ask you a question? I bought an RWS 48 that had an RWS mount on it. When I tried to remove the mount I found that all the screws had been gooped with copious amounts of Loctite and only came out with the greatest of difficulty, being ruined in the process. I sent the mount to Umarex to clean it up and refurbish it. Now after charging me $20 bucks they're sending it back without screws, saying they don't have any but I can buy them at the hardware store. I real skeptical on that... Does anyone know the screw/thread size so I can begin my miserable quest to find screws for it so I can sell the thing?
