I like you wanted something you could take apart for cleaning so I spoke to a gunshop owner who bought use to stock them and bought one in for a customer, sent it away to be fitted and was told not to send another wildcat to be fitted again by the gunsmith so he stopped selling them. It not fair for me to say any more as it wasn't me who had the experiance with the Wildcat.
I ended up buying a PES which can be taken apart the for cleaning, it's one hell of a piece of engneering and I think around the same price. Top tip with them is for field use ie: 2/3 rds fired through them if you lightly coat the internals with oil they are easier to clean.
Might be worth you doing some research into the Moderators, try to find a place selling both the PES, ASE and Wildcat mod's.
