X/RT valve and On-offs

[muirtach]

I've done a few searches, so I'm pretty sure on the answer, but I can't find anything directly relating to this.

I'm building up a new mag from scratch, seems like everyone is of late, and I'm trying to figure out why I would need the differnt on/off valves. Specifically will a standard X-valve on/off work with a classic/mini rail and a ULE body. I think that the need for retaining your on/off when going X comes from a difference in the body rails.

I have a classic rail and am not quite sure as to whether I will need a classic on/off to make the X-valve work properly.

If you're putting the Xvalve on the classic rail- you use the on/off that came with the Xvalve.

If you are putting the Xvalve in an Emag- you use the valve from the Xvalve but the on/off pin from the Emag.

Great. That answers all my questions.
