Hi and welcome to the GTA. Don't know anyone in particular that tunes that specific gun but I would be very interested to know how to acquire one of those for myself.

i think i bought it from compasseco, but it was like, 5 years back or so.  probably longer.  ive been shooting it, and it is good, but since ive never shot a FWB300, i cant compare.  im sure the original is better.  im just tired of shooting it indoors.  i want to shoot a bit further than 10 meters. its just not up to it in its current state.

Hey Thomas.... on my website is a tune guide for the B-4-2 on the "Airgun Info" page that I put up a number of years ago. There have been some changes made I believe but it should give you a pretty good idea of how and what needs to be done. Take a look here.

This kit in the link below will work for you also and is available in other places as well. Just need to do a search.
