thanks for the info. my b and c tactical/varmint stock arrived today. i ordered it from stockys. i just finished installing it and it fit absolutely perfect. only work i had to do was drill a small pilot hole for the rear trigger guard screw. there was no provision for it. you can definitely feel the extra weight of that aluminum skeleton inside of the stock. I'm not so sure i want to attempt to glass bed it just yet. well it looks like the rings and bases will make a nice fit. Going to order here in a few days. I'll let ya know how it turned out.
