Diff. rails diff. reactivity?

[ChucktheMAGician]

I was just wondering if there could be a difference in the reactivity between an AM/MM rail and a RT Pro/Emag rail. Can a difference be felt if the same valve was shot in one then switched off to the other. The reason I ask is because of the differences in rail thickness and possible sear placement?

It's not the sear placement as much as the length of the on/off pin.

How does the on-off pin leanth affect reacticity, ive never understood how it works, all I know is that it does. A differant rail with slightly differant tolerances might move the sear, hence allowing the on-off pin more or less travel in turn increasing/decreasing reactivity thats what it sounds like to me.
Can someone explain?

[Dayspring]

Actually, that was a really good explaination.

The physical tolerance from a working un to full auto is .015". That's enough to get the pin to seat or not seat.

That's why the ULT gets shimts. You are "changing" the on/off pin length.

Rail thickness might affect reactivity though. The reason I say this is b/c on my one MM w/ an Xvalve it is extremely reactive at any pressure over 700psi, but my RTP w/ the same Xvalve same on/off assembly it is not that reactive unless you jack the input pressure way up near 1000psi and on my one EMag w/ the same Xvalve, same on/off but different pin of course it is hard to find the spot but once found it is pretty reactive in manual or hybrid modes.

So does it vary AM/MM rail to rail, and RTPro/emag rail to rail or are there noticeable differences between the 2 rails do to differences in the thickness's of them?

[Evil1]

AM/MM rails are the same thing. Maybe different down to thousandths or even lower but nothing at all noticable. And I will have to get back to you on the EMag and RTP differences, I mean there are noticable differences but I not sure about thickness differences near the on/off location.

No two guns are exactly alike. If you use a measurement small enough there will be a differance.
Kind of like there probably is no true circle because if you go small enough it could be 0.000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000 0000000000000000000000000000001in off.
