Want to upgrade my .68 classic, which valves will work?

[jamesmbaldwin]

I want to upgrade the valve in my .68 classic mag, and wondering which will work, I want to have a reactive trigger also. I'm almost sure I can use X-valvs or retro valves but not sure about RT and E-mag vavles. Thanks for the help.

All the AGD valves will work except the classic RT valve. Make sure you use a .750 on-off pin in any retro valve you install.
