Just had some quick detach rings installed on my 416 ruger guide gun.

Alaskan arms LLC right here in big lake manufacturs them and installed them for me at his house. With a garunteed behind it. Anytime he says bring them back if they don't do what he says.
I haven't shot it at 100 yards yet. But have fired three two shot groups at 50 and took the scope off and fired the irons between. Six shots made two holes touching. Will get it out to 100 next week.
Happy with then so far!
