I've got both in current use and have never had one fall off or otherwise do anything other than just sit there. When I started to get enough money to start being a little pickier- I tried to get mounts and rings that I thought astheticaly complemented the rifle. On my older rifles, I've found that I likes the Leupold one-piece bases and the Burris Signature line of rings... at least until I can afford some of those fancy european turret types. I dunno, just makes for classier lines in my opinion.

I'm going to use the words "clip" and "Long Colt" every chance I get. It grinds my gears to see new members attacked when we all know dang good and well what's being refered to.
