quote Billyboy:

Out of the box my cricket was running at a steady 887fps ish
220 fill for 69 shots
Coming off the reg at about 110 bar

A year later it’s running at around 870 fps
220 fill for 59 shots
Coming off the reg at 110 bar

Is this just it bedding in ?
What should I adjust if anything..

After reading all advices, deep clean the grooves of the barrel, whips are not going to do the job, when grooves have lead build up they cause drag that will lower fps and use more air and most time accuracy not affected. Also after brake in as noted by Coda it will settle down —-> Now you have a new reference point “broken IN “.
