45 Degree Offset Iron Sights

What is more open than an A2 aperture?

Derp... I did a bad job of explaining. The open A2 aperture is fine for close up stuff, but I find that aperture useless past 25 yards, but it's been a while since I had an M16A2.
The smaller aperture seems almost too tiny, and for me something just tighter than the KAC <300m flip up sight is just the right size, and the KAC offsets seem to be just that, but I'm envisioning these as a niche for either optic down, or needing to engage a closer target with a variable scope cranked all the way up and transitioning to irons is faster.

Still might end up with one of each.

Another thought occurred to me while dicking around with this - how hard would it be to mount an RMR off the ACOG/Scope tube, at roughly 4:00 (to place it where it would otherwise be with offsets), it would even be a more upright placement for some.

There's a bunch of mounts and the like to offset various small RDS. Personally I like the lighter weight of the offset irons, and would like it more if the rear was an A1.
