Hi there ,re: tuning a air gun .
full strip down and de grease
plastic spring guides replaced for metal.
Transfer port opening made wider.
new spring fitted,
re assemble using the types of grease and silicon for the job in hand.
chrono test for ft lbs output.
should be a smoother shooter, and a more powerful rifle.
