A Couple of Newbie Questions.

[Steve Jax]

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?

[Steve Jax]

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'm trying to figure out how that works on a rear feed air source ?  ?   

I'm just not getting it? ? 

[Steve Jax]

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.
