Having a strange problem with my classic mag

[Crighton]

Ok this all started after I installed an intelli and omega rail. The marker will gas up normal and the trigger pops out and to the ready. I can fire the marker for a few shots and then the trigger will not return. The sear just stays limp with the rod not touching the trigger back and the on/off stays up. I have to take the marker apart. When I do so I can hear the on off pop out and degas as soon as I start to back the valve out of the body. It was working perfectly before the new rail and trigger frame. If I install the same valve in a spare rail and the old single trigger frame I cannot get it to freeze up like this. The valve is oiled nicely so is the bolt and bumper.

Anyone have any ideas?

i would say try the rail and frame separately, old frame and new rail, and then new frame and old rail, that might help a little in finding what the problem is

Ditch the Omega rail and try a stock rail. I'll bet that's your problem.

Make sure that the trigger rod has a gap inbetween it and the trigger when gassed up. Also, adjust the field strip screw tension. If you're hand tightening it, try fully tightening it with an allen wrench and vice versa.
