ok, I probably should have said oiled the o-rings. Here is the product that I got from the paint ball store in town. http://goldcuppaintball.com/Items/1o...0Oil%20-%201oz
to my knowledge, the MR1 does not have any kind of regulator on it, just the one that is on the air bottle. As for the springs, which would you recommend I replace first? The lower bolt spring or the valve spring?
