Hi,
What are the views on polishing the inside of a break barrel airgun cylinder? I've read that this can have negative effects, but I'm not sure.

I'd like to learn about springer tuning, and I thought I'd start off with my BSA Meteor Mk5. Don't laugh I enjoy the Meteor, and I'd like to make it as smooth as possible.
It's got a new spring from Protek Supplies, and I will fit a new buffer washer. I've adjusted the trigger so that a gentle squeeze is enough to fire the gun.
I was thinking about polishing the sears and every other surface that would benefit from polishing. Cylinder? The contact points of the piston?

Then I could try fitting a delrin spring guide, and perhaps a top hat too (btw I tried this with a Titan spring, and Titan spring guide/top hat - not a succes; the spring was way too stiff and long for the Meteor).

I know that Meteors are not made to be top class shooters, but as a plinking gun it's great fun. I'm not looking for an increase in power, just an increase in smoothness.

Cheers
