UPDATE 910 Airgun – Regulator Piston Removal Tool O-ring size

[Impact701]

I purchased this over price piston tool.

It does not grip the piston.
I contacted Newman he said there should be 3 o-rings inside to grip the piston, and to contact Bullet Central where I bought it to get the o-rings.
I have asked both Bullet Central and Newman what size o-ring does it take????

No answer from either.

Has anyone bought this tool, know what size o-rings are needed ?

Thank You
Brian

I know I could have made 1 out of a Bic pen

I found o-rings .

Never did get and answer from 910 Airguns !

I did call Bullet Central but they would not tell me what size o-ring to use !

They must be a trade secret !! ??

Get a piece of 1/4 polyethelene tubing. Works like charm and costs $1.

lol must be as you don’t even list what you used. Yes 910 isn’t the best communicator.

I was wondering if anyone was going to catch that ! ?

It is one of the two o-rings I circled as the 2 bins were mixed together.

From what I measured it is a
3.9 mm x 1.7 mm but I doubt these are metric o-rings from this old o-ring kit.

Newman from 910 Airguns has contacted me and is shipping the correct o-rings.

FYI...
910 has been relocating and moving into a storefront facility so he's been quite busy with that over the last bit. Could be the reason for the slow comms.
