Red Dot vs Reflex vs LER scope for hunting

[totallyunimodular]

I know this general vein has been beaten to death, but I have had trouble finding information specific to my needs. I have a Mosin Nagant 91/59 (7.62x54R) that I am setting up for (mainly) elk hunting. No bubba-izing, just putting on a scope via a Darrel's (http://www.gunandgame.com/forums/mosin-nagant/58116-darrells-scout-scope-mount.html) style base that can be swapped out for the original iron sights in minutes.

So, I don't anticipate taking shots over 150 yards, at least not until I put a lot more time at the range in. The long eye relief pistol scopes like this one (http://www.sportsmansguide.com/net/cb/ncstar-2-7x32-mm-illuminated-pistol-scope-matte-black.aspx?a=323030) seem to be popular for other MN owners doing the same thing. But here is my twist: this is my only gun and will be for the foreseeable future, so I want to maintain some level of self defense and that means a quicker acquisition
sighting system, which is what has me interested in the red dot and reflex systems like this (http://www.sportsmansguide.com/net/cb/barska-40-mm-dual-color-reticle-red-dot-scope-matte-black.aspx?a=428435) and this (http://www.sportsmansguide.com/net/cb/osprey-compact-multi-reticle-reflex-sight.aspx?a=556287).

Is anyone out there in Colorado AR-15 land using these types of electronic sights for big game hunting? I am hopeful that such sights can reasonably be used to big game hunting at shorter ranges (<200 yards), and I would also have an sight setup that was not too slow for SHTF situations. Strong opinions either way are welcome!

Well I'm guessing your Budget is $60 bucks. I can't speak for the other two but I do own the 3rd one on my .22cal, I do like it quite a bit as its basicly has 100&#37; FOV. But i'm not sure how pratical it would be in woods, it looks like it may snag on branches, and I can't imagine if you'd drop the rifle on top of it. It doesn't seem to be that strong for things like that. Also You have to set it with a allen wrench, not sure what your pref is, since the other two you link seem to have finger dialing. But once set it should be ok. Whats nice about it though during bright days you'll get bleed out on the dot, so you can change to a bigger dot with a flick of the rear switch.

Good guess on my price points! Yeah, basically I am trying to spend less on the scope than the gun itself. Durability is an issue, as is usefulness in Colorado high country in the fall, when it can be sleeting and snowing...
