Re: Armtech rifles?
I'm somewhat familiar with the Armtech rifles, but have never seen one in an F-Class stock. I think this is one of the two lug actions, but not certain.
The Gaulin brothers manufactured these rifles in Quebec, and all the barrels I've seen were made by Ted Gaillard in Saskatchewan.
Might I suggest that you inquire in the Precision Rifle section of Canadian GunNutz forums
