Tom,
I don't think it was tuned, I bought it secondhand without even seeing it from McAvoy Guns. It wasn't in the best of condition but i wanted something to tinker with.
I fitted a Theoben Gas Ram System to it (Very Very Quiet) and with accupell it is pushing between 11.6 to 12flb.
Although it is very smooth i can't realy get used to the recoil. There isn't much of it but the gas rams action works oposite to a spring system and so the whole firing action seems back to front.
I use my HW80 Venom Lazaglide in .20 for most of my airgunning, I am looking to use the Eclipse for close range ratting if i can pick up some open sights?
I may have some lying around from an old webley omega.
When i searched a few options for tuning, I also spoke with Terry @ T.R Robb and he said that due to webleys alloy Action/Chamber then you have to be very carefull not to damage the rear of the Action / thread etc.
Sorry i can't be of further help.
Why not give Steve Pope a call @ V-Mach, He is very helpfull & usually supplies the answers to my questions.
Cheers
Justin.
