My first crosman snr357

Scope on a BB pistol? https://www.crosman.com/product/crosman-snr357-bb-177 Sounds like you have some sort of a serious addiction going on there. ;^) A few of us here may have that same sort of problem. There is nothing I am aware of to make it easy to install a scope on that gun. But you can always drill and tap it for some rings if you just have to have a scope on it.

I put a scope on my 600 it wasn't made for one either. I used the stock sight and barrel screws and drilled the Picatinny rail as needed.
