Here is my frankenMag configuration and problem. Retrovalve vv01478, TacOne mainbody, RT Pro rail, AGD alluminum trigger frame. I am putting 1100 psi to the valve with an Air America adjustable regulator. The valve won't cycle. I can feel the resistance of the on/off pin. I believe the problem is with the on/off pin length with this configuration but I welcome dissenting opinions. If I am right what size pin do I need?

Thanks!
