Quoted from brettybluevein:I had such a problem with the magazine when I shopped one. I adjusted and tweaked as many ways as I could think of and it just would never run smoothly. It would open fine, but when it went to close, it would bind up. The end solution was to turn the mech off in the open position and just eliminate the movement, but obviously that wouldn't be acceptable to some. Good luck, and post again if you get it to work.
Are you talking about the fold out centerfold on the center ramp?....because I think the op is talking about the mech on the right by the shooter lane.
As for the centerfold mech....yeah, it's really touchy. I had some issues when I would work with it and it usually amounted to just taking it apart and putting it back again and it would be fine.
