Thank you for posting this topic... maybe my bitching can be silenced.
What I want is a simple lower third mount without QD. For example: a LaRue Tall with no QD, or a 1 piece Daniel Defense that doesn't need a bolt-on riser to become lower third. I don't want or need any skeletonized hotness, and I want minimal moving parts.
Personally, I don't feel like I have any need for QD. It's less about saving money than it is KISS. .. i.e. I'm not trying to be a cheapskate.
If I'm being stupid and should just stick with what has been working flawlessly for me (LaRue Tall), I have no issue doing so. It just seems odd that I can't find a simple, tall, box-style mount.
That SLR model is the closest to what I want that I can find.
