If you get a quote , let us/me know. I also am the lucky owner of a 10,.....which needs seals. I have resealed a mod 6 but it's velocity is not sufficient so it has to be taken completely down again to get to the seal to afford an adjustment. It is a little trickier when you don't have metal lathe to take off a thousandth or so. It is more complex but doable. There are some pretty good tutorials out there. If interested check into " another airgun blog". The mod 6 and 10 have the same internals.
Congrats on your 10.
