Update/"show and tell"

I started a reply to you like 3 days ago… then life just got way too busy for me.
Anyway, so you do have a valid point. Annnd that why I recommended he run fixed sights with his RDS. I know it doesn’t look cool, but it’s a solid & reliable backup system. He does that and it’s a moot point. But say he’s running folding sights, from my POV I’d rather have a sight, particularly a front sight stay locked in place, than have one that could get knocked down flat fairly easily against my rail when I need it.
I’ve whacked my Troy’s pretty hard, for
My pickup door and tailgate to dropping them and they haven’t lost zero much less broken into pieces.&@2

But hey, if you’re interested in getting rid of those “garbage”BUIS, I’m sure I can dig up some Magpul MBUS sights to swap with you. Hell I’ll throw in some cash to boot. [emoji846]

So I got my Magpul MBUS Pro’s in the mail and put them on my rifle. I’ll try to get snap some pictures after work, but is it normally not centered on your red dot? I’m not talking about co-witness, but I thought the rear sight would be in the middle of the glass, but its off to the left a little bit.

Also, since I’ve never used a red dot before, is it normal to have to move your head a little bit to be able to see through the back up sights?

Congrats on your rifle! I have a bunch of rifles running MBUS and they work fine. I also like the Pros but honestly MBUS gets the job done.

As far as the Aimpoint PRO, yeah, if you have an astigmatism, the dot does flare but you can still use it effectively. I do.

Enjoy your new rifle and let us know how it shoots!

A couple things. I don’t know what Aimpoint says the cowitness with the standard mount. Mine is somewhere between absolute co-witness and lower 1/3 co-witness.

If you aren’t familiar with the aspects of co-witness here is a fairly simple explanation: https://progunfighter.com/co-witness/

The beauty of the red dot sight is that you don’t have to be as perfectly centered up on the tube as you do with a traditional scope, so yeah, having to move your head slightly to get the dot on the front sight is the norm.

Remember with the RDS you are supposed to look at the target, not the dot. To see this in action simply put the front cover down, keep both eyes open, and bring the rifle to the target. You should see the dot on the target. Cool, huh?

Its close to a full-cowitness, but thats not quite what I’m talking about. I’m not talking about looking down the sights. When looking at the rifle from say, the buttstock, you can tell the BUIS are a little to the left of the “center” of the red dot. I’m not sure it messy with any functionality, but the OCD in me has to know if thats just the way it is or if I have something mounted incorrectly.

Sorry I haven’t read through your latest posts, but have you zeroed both the BUIS and the red dot at the same distance? That’s what I do. I have not found a situation where I zeroed both sighting systems and had the dot to the left or right of a proper sight picture when using the BUIS. I’ve had the red dot full co-witness with a proper sight picture with irons and I’ve had 1/3 co-witness with irons; but the red dot was in horizontal alignment (windage) and positioned above my irons. If your red dot is to the left or right when you are using your MBUS, then something is not zeroed properly, or perhaps a mounting issue.

ETA: I noticed you have a free float rail. If your rail isn’t perfectly aligned with your upper then you can have some issues as you are describing. But usually it shows up when you are zeroing the irons, as you will have to make beaucoup windage adjustments to achieve zero. Just a thought.

I haven’t zero’d the sights yet, so I suppose it may change what I’m seeing, but it’s not as I’m looking through the BUIS. I’m talking the red dot sight as a whole and the rear sight as a whole. They are both on the rail, so I figured they would be “in line” but it looks like the rear sight is more left compared to the red dot sight. It may just be the way it is, but I noticed it and I can’t stop noticing it its off a little bit but everything seems to be mounted correctly.

You’re worried about nothing. Tolerances are such that not everything is going to line up perfectly. That’s why sights are adjustable.

Zero your BUIS first, then zero your Aimpoint. After that, everything should appear more centered as you look through the tube.

I tend to do that. I overthink and I notice this most silly things, but I can’t put it out of my mind. I just don’t know what it is supposed to look like. I don’t want it to be mounted incorrectly (it seems like it’d be hard/almost impossible to mount incorrectly, though).

That’s the order I plan on doing it. I was excited to get up and go to the range today, but my back (damn genetics) had other plans. I can barely walk. Looks like I’ll be going sometime this week.
