Loving the site especially the Gallery  :), but I do have a couple of Questions I hope you can help me with;

I stripped down my King Ratcatcher for the first time yesterday and got as far as the breech hex screw or should I say Micro screw could anyone tell me what size Hex key I need for this?

I have been looking at GMAC custom parts I am currently getting 9.5ft/lbs on Superdomes @ 14.5Grn on HPA could I benefit from swapping out the standard probe and hammer spring for a GMAC .22 Extended Hollow Probe and Power Hammer Spring with Brass Guide and what gains do you think this would give me.

Thanks,


Steve.

Is your valve pinned?

No the valve is standard, my HPA conversion is;

48ci 3000psi tank remotely connected through 850psi regulator to non return pin valve in the rear of 88g bottle screwed into gun.
It's the same setup I use on my smk 78 with no problems :)

Gotta agree there, always better in the flesh, fitted my bits from GMAC now getting 10ft/lbs using Milbro Caledonian Ultras 14.4Grn.
I'm happy with that obviously a longer barrel would increase power maybe a future project.
Going to be giving it a try out down at the range tomorrow I will be keeping an eye on power to see if it increases when parts are bedded in.

I don't get what you mean the 88g bottle has been professionally fitted with a non return fill valve when plugged into my remote bottle it acts as a reservoir my regulator on my feed bottle is set at 850psi so the gun runs at 850psi in Summer I will probably fill with Co2 and run it unplugged :) Duel Fuel.
