I have an old BSF s60
I found it on the attick in my friends house, it was standing there for several years ans was totally rusted and dusty.

I tried to make it look better but there are still soms remains of oxidation on the iron of the gun, and also it oxidades back quickly.

Also the firepower is really bad, as one toled me it would be a 850ft/s rifle nothing much of it is noticable, a clear shot at 10meters even is hard to make.
The trigger also isn't all that good.

Does anyone have any suggestions how to make this gun back worth shooting with?
