Rumour has it that when getting the Cricket ready for sale on the UK market, work arounds, rather than proper replacement parts are employed in reducing the power from the 30ish fpe they import at, to sub 12 fpe. I don't really understand the impacts of what's done to the rifles 100%. But when I see mine varying into fac power levels, it's time to get something done. (Apologies Phil, I can't wait until next winter to deal with this particular issue, but thankyou) What I am aware of is something is done to the FAC level regulator which is then reinstalled and the hammer spring is simply cut shorter and not 're dressed, or if dressed, done not so very well (like mine). So, a venture into the darkness, any advice/tips gratefully received I have ordered:- A Huma reg. New hammer springs x2 (one to bugger up + a spare). An external, dual HST adjuster, coarse and fine adjustment. The original was made if cheese! I've got, 1200 grit wet n dry Autosol polish Time I'm slowly getting my head around shot cycles, lock times, hard springs, soft springs, long springs and short springs. I've asked Huma to set the new reg at 95 bar for my initial reassembly. Wish me luck!
