Is is possible to switch barrels on a Diana 34? I was thinking of getting a .22 barrel for my .177. Maybe a .25 if I could find it. If so does anyone know where I could find them?

The answer is YES ! and where how about here ...link ...

it will cost a little under $150 .. OR

pay $10 more and get a new RWS 34 in 22 , then you have one in each caliber !!

I would choose the second option .

Thanks Frank,

I thought it may be cost prohibitive. I agree the second option makes more sense.
