Do I need a new sear for am RT valve?

[trains are bad]

I just traded my classic for an RT valve, do I need a new sear or rail? I have a classic mag.

Also, it has an emag pin in it, what effects will that cause and what's the best way to go about getting a longer pin?

You don't need a new sear or rail. You do need a new on/off pin that is 0.750" long. The emag pin will most likely make it go into runaway. You can buy the pin from http://store.airgun.com

instead of buying the pin at the online store, I'd check the classified forums... Someone may be willing to send you one... Or talk to roguefactor or one of the other dealers around... Of course they'll have some lying around
