[AlexNation]

Hello everyone? 
Can someone with a FX impact could tell me or measure for me .the threads on the gun where you screw in your bottle. Looking this info for a new built.
The bottle threads are m18x1.5. I am looking for the inside threads of the valves bottles that screws into the gun.

.
Id like to use a fx bottle so i can make my new built has a take down rifle.

I'd like to know as well, I measured with my calipers and the outside of the threads on the gun are +/-12mm and I'm pretty sure 1.25mm from top of thread to top of thread.. My guess would be m12x1.25. Just an educated guess not for certain.

Thank you for the answer. At least you got the exterior measures for me. Its very appreciated. Maybe the pitch is different and some one will chim in. Do you have n idea of the length before the "nipple". I wonder if they are the same as the fx verminator.

"AlexNation" I wonder if they are the same as the fx verminator.

I believe they are the same. There was a thread where Ernest mentioned that this is the valve FX bottles use http://www.bestfittings.co.uk/shopexd.asp?id=731

I got a M3 small CF tank from a guy here @ AGN. I needed a CF bottle only for my Leshiy2 build. It was a hell of a time removing that bottle valve adapter from the tank. I had to make a tool/block to clamp it in a vise and break the glue with heating the CF tank neck. And they used two glues, one was yellow in the middle of thread and the other brown against the flange.

So the thread pitch is 1.00 mm I measured from the adapter hole as it was asked in the picture very above.
