Feinwerkbau 300S rebuild needed
Recently bought a 300s left hand that may be in need of a rebuild. Hoping to do a chronograph test soon to see what is happening with FPS. 1st thing I did when I got home with it was put 3 cleaning pellets through it and 1 did not quite make it out. Still very accurate and smooth. Can you recommend someone to do the work? My interest is for pleasure only, not competing. I am in NW Ohio. Thanks for your help.
