I had mine like this with an ACOG compact for awhile. This is no good though. It's too high and I had to almost jury rig the mount (backwards with the sight shifted to the back of the mount) to get it to sit back far enough. I use this ACOG on my AR now, which it is much better suited to.
Now I have it like this with a T1 Micro. Much better set up. I think this is by far the way to go with a no-mag red dot set-up on a Swiss Arms. You can use the red-dot, the irons or both. The red dot sits right on top of the front post in the sight picture. That is Kyle rail by the way, one of the world's few pieces of indestructible technology!
