    I need o rings as well ! My Dad's old gun. Did anyone find replacements or did you have to improvise??

    Thanks for the correction.

    You need a special pair of (reverse) pliers (cheap) to remove the retainer clip to get at that small o-ring..

Check out www.mac1.com. Tim can sell you the o-rings or customize your gun to another level (see the LD pistol).

I have a Mark I that I took apart and was able to replace all o-rings with bulk ones found in the hardware store.  However, I could not change the one for the needle in the valve, and it still leaks.
So, you could contact Mac1 out of the US at mac1airgun@att.net.
He would be of help as he modifies these things and has full parts kits available.
Mine is a pre-1975 unit and works well except for the leaking.

Hi, I am trying to remove a brand new CO2 cartridge I just put in a new Gamo PT-85 Blowback pellet hand gun. As I'm unscrewing it, gas is leaking out. HELP.


Hello K Brink,

Kind of like deja vous (all over again )...
Pretty sure: This is the same Question I answered
yesterday (no / yes? ).

There is no going back... Once the CO2 cartridge is
pierced... there is no way to salvage the cylinder
until it is FULLY expended...

If you unscrew the chamber the CO2 will ALL be released.

Just ONE word... If your cylinders are depleted... ALWAYS
check that the SEALING O-ring stays with the hand-gun.

Just make sure yur SEALING RING is still in the "gun"
and NOT STUCK to the ... co2 CARTRIDGE.

I am just saying...

((been there... Done that))...

The dovetail groves are closer on a pellet gun rifle and they ca not close enought.


You probably have rings designed for a standard Weaver style scope base.... you need "3/8" groove .22 style" rings... available from your local gun shop.
Hope this helps, Mark the Gunsmith

Please give feedback!

Go to www.airgundevelopment.com and scroll down to the link that says crossman valve. I used these pictures to get mine back together. It's not an exact science, but it sure does help.
