10-18-2007, 07:18 PM
I have a mr1 with rocking trigger and alamo city low blow bolt running co2. I took the gun apart the other day to clean it after playing as I always do when i put it back together i could here air leaking inside the gun where the bolt is. This has me puzzled i took it back apart and checked all o-rings they look fine. Any thoughts on what might be causing this? thanks
hmmm check the cupseal, its the little white thing that is attached to the valve pin, try to see if its a little loose and if it still leaks you'll need another one,
cupseals are cheap to replace, so if thats the issue i wouldnt worry about it much,

Is the bolt cocked when you aired up the marker?
Have you checked the cup seal & cup seal sealing surface?
