Mr4 air problems
So I did get the mr4 but when I played it would shoot 1 and sometimes 2 balls and then not fully cock. I had plenty of air, checked the o rings and oiled it but it still won't work. I an using a remote line if you think that is the problem. Please help!

There isn't a regulator on the MR4, Steve2012.

Sniper Boss, perhaps you may want to try screwing the adjuster screw in a bit, and then double check your velocity at the field.

Re: Mr4 air problems
That's the valve set screw. If it was loose, it could cause serious marker malfunctions as well as cause your issue. However, it is most likely not the root cause in this gentleman's case since that issue is very atypical. It would be something to check out, but I think the velocity adjuster approach may be more fruitful.
