I hate the "set screw pushing a ball" design on the dropkicks and many other rails. So while I get that dovetail is going to be the standard, I'd rather just have the standard 10-32 screws. You guys should check out stacking a small on/off drop forward on a dropkick. with the 45/68 tanks I use, it puts the butt right in the curve of my shoulder with the top of the marker at eye level.
