Everyone has unique issues and desires. To keep the handle
(which I did) means the handle aiming trench ("HAT") is about
equal to "cowitness" AR iron sights. For me, looking down the "HAT" requires a FIRM cheek weld - I feel as thought I am adding significant pressure on face.
This is a a non scientific overlay of 2 small 1913 rails which I threw on handle-less KS7 and mounted MAGPUL iron sights. It shows a very small disparity between "AR cowitness" and "HAT".
ANY Red Dot ("RD") will require some adjustment. This setup is a "lower jaw weld" but when using "RD" - I try not to worry about any weld and just aim. Training training training.
The only way to minimize extra height would be:
- shortest "RD" possible - micro "RD" (RMSc) with small window will help lower the dot compared to the biggest windowed "RD"
- shortest mount possible above "HAT" - "made for AR handle" scope mounts as suggested was too tall for me. The mount I use presents 1913 rail as low as possible
- the only way to mount "RD" lower on the handle requires altering physics:
a. cutting side walls of handle and mounting to floor of trench. I actually pondering doing this.
b. If you can find anything narrow enough to fit inside "HAT" - good luck with that.
c. I also pondered mounting "RD" upside down with window in the "HAT" but again finding anything narrow enough was impossible which would mean an upside-down mounted RD with the sides of handle cut out and some insane mounting bracket.
Here is a RMSc "RD" for 9mm pistol just sitting on handle: so there is some advantage to finding a way to make THAT happen. But even adding a mounting plate under it (it needs something to water proof the bottom where battery goes) raises the micro RD a bit, and that plate needs something to bolt to..... There is a made for KS7 RMR footprint mount for handle
but RMR is a full size pistol "RD" and probably places window exactly where 1913 mounted "RD" window is.
It is important for me to preserve "HAT" view under "RD"
in case "RD" fails or falls off or whatever. In fact, this kind of rail mount creates "rear Ghost sight" just by itself. I think the "made for AR handle" scope mount
has a giant screw going vertically through the mount which makes looking under "RD" all but impossible - but I could be wrong.
- trench floor 1 5/8" above the cheek weld
- Bushnell TRS-25 Red Dot center 2 6/8" (almost 2 7/8") above cheek weld
For size comparison, below is "RD"
on Cowitness Mount
(as it would be on AR) on top of KS7 mount: AR Cowitness mount is .83" and offers a big peek through square tunnel. Not much to learn from doing this - just comparing sizes.
This would be beyond 1/3 Cowitness.
So that was a bunch of opinion on top of a few facts.
