Gunsmithing Trigger options for custom 50 BMG

[AIorBust]

I'm looking at getting a Model 22 tactical trigger from X-Treme Shooting. I tried calling the number on the web but I'm thinking he is out hunting or something.

Does anyone know if this will fit on a McMillian Tac 50 repeating action and if so how involved the installation?
