I'm currently parting out my mag so that I can build a ULE RT-Pro. I'm getting a RT-Pro rail for it. Now, I realize that the sear and sear pin are different from the mag to the RT-Pro. I really just need to know the difference in the on/off assembly. I read on the AGD site under the go X-valve program that you need to keep the RT-Pro's on/off assembly if you are using the go X-valve program. But, I don't have an on/off from a RT-Pro to keep. Do I need to order a whole on/off assy.? Or, can I just buy a different length pin?
Thanks for your help,
Darrick
