I just got an ACP 2 o-ring bolt, but when I put in my MR2, air leaked out of the barrel. There were no leaks when I switched back to the stock bolt. Any suggestions or people who have had this problem?

Are you cocking the marker before you put air to it?

Yes before you screw in your air tank, cock the bolt/striker back. If you dont it will leave the valve open & leak. Try it & tell what happened.

the bolt pin between the bolt and the striker is probably a little farther ahead meaning that when the marker is uncocked it is pushing the valve pin back a little and not alowing your cup seal to seat and restrict the air flow. either you can shave a small amount off your valve pin or just cock your marker before you air it up. Always make sure to oil your marker to as it could just be that the valve is dry. Try to cock the marker then air it up if there is no air leaking the problem is as I described above with the pin. Not really a big deal just cock the marker before you air it up or shave a little off the pin

If he shaves the valve pin thats gonna decrease the valve dwell & possibly cause more problems down the road.

Cocking it worked fine, I don't trust myself modding the bolt, thanks for the help guys

wow first it was the valve pin not the bolt! LOL and cocking it first effectivly does the same thing pulls the striker away from the valve pin. So if you dont mind cocking it first its alot simpler.

EDIT: What problems do you think that would cause in the future James? Just curious as I have done it before with no problems (YET!)

haha my bad well either way I don't think it'd be wise for me to mess with it

As a rule, you should always attach air/CO2 with the marker cocked. If you have used a tippy before they will hiss like crazy at first if you forget to cock it prior to connecting it to an air source. At most fields (that I have been to) it is part of the standard instruction to the rentals and new players.

Wow I've never done that with any of my markers, including several Tippmanns, and never had any problems. thanks for the heads up though.

OK, now it leaks cocked with both the stock bolt and ACP bolt. Any help??? Air is coming out of the barrel

Fire it a few times after you put a few drops of oil in the asa.

if that doesnt work put a few drops directly on the cup seal. If the cup seal still leaks change it with a new one. Your marker should have came with a spare.

That did help, I oiled it and changed it with a new one, but there's still a tiny leak that I can just barely hear if I listen closely. I don't think it'll be a problem since it's so small, but is there anything else you can think of?

not if the leak is out the barrel. you could check your valve and make sure there is no nicks in it. but usually air leaking out the barrel is a cupseal problem try shooting it a few times and see if it stops it compleatly. Probably will.
