I remember reading here a while back that we stay away from vertical split rings. I see that many QD styles from what I would consider top shelf manufacturers, LaRue, American Defense for example offer just such rings. Is this a function of the rings being integral to the base? I wanted to use a QD base for the LPVO I will mount on a Colt 6920 flat top (with standard FSB)but of course do not want to risk any damage to the optic. So if in this case the vertically split is safe to use, I then have a few more options. If not, I can sniff out a QD base with the more traditional horizontal split. As always, I appreciate input and advice from members.
