Ideally I'd love to just borrow a set, need to check what the end gap clearance is on a set of barrels I've just acquired. Ideally I'd like to reuse the original pistons as the gap between the piston and the bore feels really good, however I prefer to test the end gap as a better indicator of how worn the bore actually is. If the bores are not too bad I'll maybe try another set of standard rings or get them rebored .25mm.
Let me know if you have a set or sets lying around, if one set works out I'd be interested in buying the others.
