Hi all just wanted to know if anyone on the forum has detailed knowledge of tuning the Noblesse ie internals, like how to polish the valve and other detailing jobs you could do to get the best out of the rifle than comes stock, I did get some details on springs from rami939 and amoxom but would like to hear from anyone, on how to mod the internals to get the best out of the rifle. It is already a good rifle but allways hear that a tuned pcp is allways miles better than stock. If anyone can give me some insight and knowledge on how to achieve this I would be eternally greatfull. Most of you pro airgun tuners live in different countries i'e US and I live in the UK but would really like to learn on the ins and outs of my rifle, I did mod my 2 of my air arms pcp's with new hammer springs and regulators and work on the transfer port, but would like to learn from you guys that can achieve not only power adjustment, but shot count and accuracy. So if anyone has any advice on how I can learn how to tune my own rifle, from your experience or from reading materials which I cannot find none, please leave a comment thx.
