Trijicon RMR on RM33 mount on a Mossberg 590SPX

I have my eye on an Trijicon RMR for my Mossberg 590SPX. Does anyone here know if the Trijicon RM33 mount will put it at absolute co-witness level with the included LPA iron sights?

Jay, I would suggest that you consider something along the lines of a vortex spark solar instead.

The reason is something that is often called the Binden Aiming Method.

Basically with the spark solar you can use it with the front lens cap on. Assuming you are a right handed shooter, you can use your right eye to see the red dot, and your left eye to see the target.

This leaves you with a full peripheral view and that allows you to apply long leads like we do on the skeet field. That is not possible when looking through the limited field of view of the optic.

I have a couple Armson OEGs on a couple shotguns and I shoot as well as anyone on the skeet field using the method I described here. But I do plan to add a Spark to my 1301, and that allows the red dot to be used in the normal way for static or slow movers, or the Binden method (with objective lens cap on) if long leads are involved.

Not understanding this both eyes aiming thing is the reason so few people shoot skeet with a red dot, but with a positive attitude, you can do it as long as you have decent vision in both eyes. It's also advantageous for people who are cross eye dominant as it allows then to acquire the red dot with their non dominant eye, and use their dominant eye to track the target.

You could do the Binden thing with the Tricon RMR if you could find some sort of cover for only the front lens, but I've never seen such a thing.

The Spark solar makes it easy because it comes with both caps and they are captured so you wont loose them.

Named after the founder of Trijicon apparently. I’ve always been a believer in both eyes open for shooting and I can’t imagine the RMR being an issue with this. I will of course try before I buy.

I phoned Trijicon and it seems the RM34 would prevent usage of the factory sights and the RM33 is the way to go for mounting on a 590SPX.
 
Well, strictly speaking it is called the occluded eye aiming method, but someone had to come along and try to brand the phrase for marketing value. I would not put Binden on a perch for it as he did not invent the concept. There's always some shooter trying to brand something in common usage even if it's been in use for years.

The point you seem to have missed is that covering the objective lens so the right eye does NOT see the target and only sees a black back ground and an aiming point is the key to occluded eye aiming.

I know it sounds counter to logic but in practice it's just too distracting to combine both images if you do not cover the objective lens of the red dot.

I’ve seen clip on killflash adaptors for the RMR. Could be modified to completely cover it. Or electrical tape. :)
I’ll experiment.
I’m left eye dominant unfortunately so I’m already naturally/unwillingly relying on my left eye anyway. But I noticed that a friend’s red dot helped me tremendously.
