Hypothetical irons-only AR

[malakili]

I have a Colt 6920 that until recently had a Bushnell TRS-25 on it. It also has a Magpul MBUS rear sight.

While practicing a bit with the TRS red dot I realized I have a lot of trouble using the optic properly with both eyes open. I mostly just get double vision.

Long story short, I think maybe I want to roll with dedicated irons. If this were your rifle, what make and model of iron would you ideally go with, and why?

Thanks.

The LMT A2 rear sight is a little spendy but it's top quality and you don't have a carry handle weighing you down

Depends what you want to do with it but I just put a Daniel Defense A1.5 fixed rear on my 6720 as its only sighting system. It is rugged, light, and simple. With the A2 aperture, should be good to 300m or so.

I'd also figure out why I'm getting double vision with the RDS

It's not the sight, it's you.

If you see two red dots (double vision), you'll see two sight pictures with using the iron sights.

I'll assume you are right handed, but are you right eye dominant?

Friend of mine sees double...with each eye. He gets very frustrated during our pistol matches and has trouble with red dots as well. He said he has to choose which dot is real and which is the 'fake' one.

 

[malakili]

Thanks for the replies so far. I like the look of that dd 1.5.

Not sure how to explain what's happening with the red dot. I see the dot/target with the right eye and the environment/target with my left, but the two target images dont align perfectly, so it just ends up confusing. I am left eye dominant/right handed.

Im certain its me and not the optic, but im definitely preferring the traditional sight picture using the mbus only.

Focus on the target with both eyes and see the dot in your FOV. Treat it like a cursor, point and click.

I also use the Daniel Defense A1.5 rear sight and their matching front sight for railed gas blocks. Spendy, but great quality and hold their zero.

If you have to squint the left eye to use the optic, do so....you'll probably have to do the same thing with irons, I'd think, so I don't see how switching to irons really addresses the problem?

Also, do you shoot with glasses? Your problem may be your glasses prescription (or perhaps lack thereof).

Definitely get the eyes checked as that is just good maintenance. As for irons on an A4 type upper, I'm a big fan of Troy Folding battle sights with a front HK type sight. Works well for me.

Best,

Don

as benEzra mentioned, if you have to squint a little ( not close the eye) that's fine. i squint ever so slightly no matter which optic or sight i'm using. it may have something to do with varying physical differences between your two eyes.

that said, i'm running my 6920 with irons only right now. i have the magpul mbus and the lmt a2 rear. the lmt is a great sight.

I have to do the slight squint to get a clear sight picture too. I have a S&W M&P 15 and put a TRS25 on it for a while. It's a good dot, but on sunny days I had to crank it up to see it and the dot became bigger than the target. I'm getting better results with the stock MBUS aperture sights at 100 yards. The right prescription on my glasses helps greatly.

I am left eye dominate and right handed. I slightly squint my left eye to better focus my right eye and I shoot just fine. With practice you can retrain your eyes. I no longer have to fully close my left eye to shoot and on close, 10y or so, I can shoot with both open.

If you don't like the TRS red dot, I'll be happy to take it off your hands.

But seriously, if you want to sell it let me know. I could use another RDS for my rifles.

A different sight will not fix your problem. If you like what you have just put a blinder over the other lens of your shooting glasses. If you decide to change sights you will still want the blinder.

 

[tuj]

If you get double vision with a dot, I have to imagine you would have the same or worse problem with the front sight. Are you cross-dominant? If so you can get some angled scope mounts to put the dot in front of your left eye. You should definitely not be seeing two dots.

 

[Defc0n]

Being left eye dominant it would probably be easiest to just see if using your left eye to look through the sights solves the problem. I'm left handed but right eye dominant and just learned how to shoot right handed so I could use my right eye.

To help us (military) focus on using both eyes (at closer ranges mind you) we would actually tape over the objective lens so all you could see is the reticle that's lit up. Forced you to be able to match up the two pictures to hit the target.

Diamondhead flip up sights.

 

[atomd]

If it's dedicated irons there's no need for a flip up sight at all. I would get a rear sight from Daniel Defense or Larue. If you want to have a same plane aperture you can change those out for an XS same plane aperture. I'm debating setting up a rifle like this and I've used both of those sights along with Troy (before they went bad) and you can really flip a coin, they all work very well....just pick the one you like the best.
