Got a new optic to try out on an AR15

[M1A4ME]

My eyes have issues.  Can't see the iron sights without glasses (can see the target fine).  Red dots like my Aimpoints and others are slightly blurry with my glasses on and really while looking without my glasses.

The other day I saw a thread on similar issues on another forum and someone suggested the Primary Arms SLX optics.

I took a look at them and finally ordered an SLX Mico Prism in 1X.  Green reticle rather than red.

It came in the other day.  Haven't put it on a rifle yet.

One thing different about every other red dot I have is I can adjust the ocular lens so the reticle is nice and clear without glasses.  I set up all my scopes that way, for use/shooting with my glasses in my pocket (or on the bench). 

The reticle will take some getting used to but at least it's a nice clear/sharp reticle.

The eye relief is advertised to be from 2 to 7 inches, so that should make it easier to have where you want it on the rail.

It has an etched reticle.  So even if the battery goes dead or there is an electrical issue of some kind, the reticle is still visible/usable.  It's just black instead of green.  That appealed to me, too.  I like back ups for what ifs.

I've never been impressed with my groups with a red dot on a rifle.  I much prefer a scope.  My groups are better with scopes.  But this reticle has the chevron design with a nice little point at the top.  I can shoot nice groups with my ARs that have the SUIT optics on them (pointer with a tip that comes down from the top of the field of view) because I can put the point/tip on the target more easily/repeatably.  I'm hoping the upturned point/tip of this optic will be similar.

Oh, one other thing.  It comes with a combination of spacers/screws so you can set the optic above the rail anywhere from just over 1 inch to just over 2 inches so you get the height that you like for cowitnessed back up sights.

Now, to pick a rifle/carbine and get to the range for sight in and see how I like it.

I haven't used a red dot on rifles yet but just recently purchased a Glock 48 MOS and set a Holosun red dot sight on it. My eyes just aren't what they use to be. The Holosun has a choice of a 3 minute dot or a 32 minute circle with hash marks or a combination of the two. So far the combination seems to work the best. I've had a J Point red dot on a Ruger MK II for twenty plus years. My biggest problem with red dots is I tend to find myself needing to center the dot in the sights screen. I'm fully aware that as long as the dots where it needs to be on the target the shot will land there but old habits with lining up sights die hard.

When I got my RMR on my P07 I remembered an experiment one day at the range.

I shot 5 shots.  All five shots with the dot on the center of the target, but each of the five dots at a different spot in the lens.  Top, right, left, bottom and center.  Still had a group at the center of the target.

I'm sure you'd need to practice doing that in order to break the habit of wanting to center the dot in the lens.  I know I would.  Not sure about red dots on rifles, never tried that.

I'm beginning to understand why on old lever guns you sometimes see the rear sight turned around or reversed backwards. Didn't use to make sense, now it's beginning to dawn on me how smart those old shooters were.

The Primary Arms prismatic is a great optic for those of us with astigmatism. Being able to adjust the diopter is also a plus.

It does have a bit more parallax than an Aimpoint or other similar sight, but if you work to maintain a good cheekweld and keep the reticle centered, parallax is fairly minimal, particularly at ranges where you’d use a 1X sight. 

My brother just put one on a PCC. With his eyes, Red dots on a rifle have become unusable. Neat little sight.

Hope it works for you.
