Anyone who tunes hatsan 125s?

My hatsan 125 group is opening up again I already sent it in for repairs because the piston seal burnt out. I heard hatsan piston seals are mostly damaged from the factory because they don't deburr the inside of the compression tube. Do you know any shop or company that will tune mine up. The only shop I know that'll do it is precision pellet. But they got a lot of bad reviews.

MikeyB is sort of our hatsan springer expert.
