Will that be ok as my bottle that came with the rifle don't need the O-ring it just screws off so that bottle valve will still fit the rifle ;) cheers for your help ATB Phil.
Well there is an O-ring.....
It is located on the depressing pin in the Reg!!

So these MFR compatible valve seal on this "Internal" O-ring!!
Also FYI... the difference between the valves is the diameter of the opening of the valve!!

The opening is larger to allow the O-ring to fit and seal.. As it open the valve!!

Yes the bottle on the left is the exactly the same as the one that's fitted to my MFR the other bottle i got off my friend is fitted with a different valve its like the one on the right so i took it off so if i get the MFR one from Best fittings will it fit the rifle sorry for all the questions ATB Phil. ;)
Well Best Fitting Claims it will....
When in Doubt Ask them!!!

There's been some info on here about the threads on some BF components; valves, reg testers, QF etc where the threads are a very tight fit when matched to Theoben components.
I've had a couple of second hand bottles where the the valve threads have been very tight for the bottle adapters. May have been BF valves on the buddy bottles???
Cheers Fellas i will ask see what they say ATB Phil. :) ;)
Let us know how it goes Walk.
