If i have a rt retro milled for ult, can i take out the ult and go straight Rt again?

I would think so. X-valve can take both so I can't see a reason why it wouldn't.

Yes. When you have the on-off area milled out, it becomes the same as all newer retro and X-valves.

is the ULT a straight drop in replacement for on/off in the RT Pro valve?

I'm using an RT Pro in one of my Egomag's and want to reduce sear tripping force needed for MPA3

If it is an original RT pro, the it probably uses the single oring above the on-off top and is not ULT compatible. Take the on-off out and check to make sure.

The retro. And first gen pro only have one o ring on top of the on off. You would need to have someone like Luke mill out the on off hole to use 2 o rings. When that is done then a ULT will work. And to go back to a standard rt on off you would have to use a dual o ring setup.

The original first generation RT pros only had one oring so they won't use the ULT. The RT Pro labeled X-valves will use the ULT.

The guaranteed way to find out if it will accept the ULT is to check the on-off area. If it has an indentation that requires a single oring, then it won't accept a ULT unless it is milled out. If the area is flat and uses two orings, then it will accept the ULT without any modification.

Post up on how it goes. I'm torn on having this done to my trusty old faithful RT.
