Well after I don't know how many years of pondering on what optic I wanted to mount on my AR I finally made a decision.
I'm going with a Millet DMS.
Given my cross dominance issues, I figured that if I was going to have to shut one eye to get proper sight picture that I might as well have some magnification available. For those not knowing what I'm talking about: I'm right handed, left eye dominant and in order to get a clear sight picture with an Aimpoint/EoTech etc; I have to shoot lefty and I'm just too stubborn, cheap and lazy to change.
I was about to go the Aimpoint w/ X3 magnifier, but I just don't want that much crap hanging on the rifle. Not to mention that I'd be paying for two optics and two mounts.
When it came to looking at units w/ magnification none really fit what what I was looking for until I came across the Millet. The other major contender was the Leupold CQ/T but the Millet goes to X4 and the lower cost was attractive.
Edited to add: Another unit I was looking at was the Trijicon Accupoint 1-4X, but I don't care for the current selection of reticles, however the tritium power reticle I think is a definite benefit and once I try out the mounting scheme below, I will probably start shopping around to an Accupoint 1-4X of either the green or red triangle variety End edit
I managed to find a DMS for sale on another forum and picket it up at a decent price. Now I just need to figure how I'm going to go about mounting the scope on the rifle. I have what appears to be a neat, somewhat original idea, but if will be costly and have to wait.
It seems that from the pictures I've seen with the DMS installed on an AR that in order to get proper eye relief when using the magnification that the rear objective will be over the folded down rear BUIS, so there's no hope for co-witnessing the irons. Looking at most standard mounts this means that in order to switch to the irons from the optic in case of a failure that I would probably have to go with some from of QD option being either screw type posts or throw levers which would mean that if I ever had to go to the irons, I'd be either discarding my optic or fumbling for a place to put it.
What I came across that appears to be a better option for what I want to do is the LaRue QD Pivot mount.
I figure that if I mount the scope using two pivot mounts that in the event of a failure I can just grab the scope, pull it to the rear and rotate if out of the way and lift the BUIS. In order to make sure that I would have enough rail, I found an ARMS #38-EX Swan rail on another forum that will add another 1.5" of rail and still provide a BUIS. As this is somewhat trial and error as I haven't mounted an optic on an AR before, I'm buying used parts to keep cost down until I figure out if this set up will work for me.
Unfortunately it looks like I'm going to have to shell out $300+ for the LaRue mounts as the only other maker of such a product is Burris, and that product won't be out until some time in 2010 .
So am I crazy or does this sound like a decent set up?
