If you put the .22 barrel on the 80 you may even have to detune it as well. If its not a MK1 80 sell it, if it is a MK1 keep it forever.

I agree they are a big old lump but I only shoot mine in the garden so its not an issue, and why all this anti .22 sentiment, up till Fred Grimwade everybody thought the .22 was the Dog's.
