I have a Trijicon RMR 08 on order for my ACR. Does anyone know what size mount I should purchase in order to obtain a co-witness when using the MBUS sights?

I have one on a pistol so can't comment on a rifle mount but I will say it's a pretty neat little sight. I went with the dual illuminated w/ 9MOA dot for that application.

I think LaRue might make a mount for them too but I may be thinking of the Docter sights.

cjt50 and DSM: Thanks for the feedback I will take a look at both and let you know how it works out. The sight has been on back order since Feb with no indication of when it will come in.

Check out the Insight MRDS instead. It's got a cleaner 3.5 MOA dot, is properly "weaponized", and sports an Eotech-like protective hood so your optic doesn't get mashed up.

I've never been all that impressed with the RMR personally. Not a fan of the darkish lense coating or distorting lense shape.

As for mounts, ADM is the way to go. It's tool-less, and clamps to the rail in a way covers more area, unlike Larue which wedges the mount into place.

Here is the MRDS with ADM mount



MRDS vs RMR

I have the dual illuminated RMR so it doesn't use batteries which I like very much. It's built just like an ACOG so as far as durability it's on point as far as I'm concerned. The amount of abuse it could take I would think is limited to what the mounting screws can endure. I've never had much exposure to the Insight models except through an unfavorable review on the XCR forum. I'm sure either model would probably work though.

What you might consider is rolling with a Burris FastFire to see how you like the small red dots. They're decent optics for the price. And then if you feel you want to try an RMR or whichever you'll have a spare sight as a back up.

Have you ever had a chance to compare the RMR to the older Trij Reflex? (smaller 24mm one) I have one of the older reflexes with the triangle and I love the reticle and it's very accurate in the correct lighting conditions. However it will washout during low light conditions more times then not.

No I havent compared the RMR with anything else. I have a Trijicon Accupoint and love it so I pulled th trigger on the RMR. Still waiting on it to come in. I will let you all know how it is once I get it.

I want a dual illuminated RMR for my Glock 21/20 longslide, but wouldn't want it as the sole sight for my ACR... unless it was on top of an ACOG, that is. ;) In the RMR budget, you could do an Aimpoint PRO, though if all you want is a red dot, though.

Here is a question: why not the Aimpoint T1 or even an H1.

In terms of MRDS, it's the king of the hill. Great battery life, durable, easy to use, and tons of mountain options. It recently got a approved to be a backup optic for sniper weapons in the Army.

In general, I'd probably take a T1 over any other RDS on the market, mini or otherwise.

And the word is getting out. The T1 is turning up in all kinds of places that many didn't expect when it was first shown a few years ago.

I have no experience with either the T1 or H1 (not that I have experience with the RMR). I do have an Accupoint and love it, and am willing to gamble on the RMR.
I ordered the RM08 which is a 12.9 MOA dual illuminated triangle, with the tip of the triangle providing precision recital location. I guess I wont know until I get it, if it
was a bad choice or better suited as a BU sight to a scope. I will keep you all informed though.

The 12.9 triangle is a great reticle. Using the point really extends the range of it. I have it in an old reflex site. Look forward to your observations when you get it.

The RMRis an awesome sight. I have 3 on pistols and 1 on a shotgun, all 8moa LED. Especially on pistols, the dual ilum models wash out when used with a white light. For a carbine there is no reason to get an RMR over a T/H-1, especially at the prices you can find them for these days. On pistols, RMR LEDs are incredible.

Ahhh, thats what I was afraid of. (wash out on dual illum model) I like the triangle reticle, it is clear even without glasses. The LED style red dot, (Aimpoint, RMR led models etc) are unforgiving without glasses. (multiple dot instead of 1 clear one) Wish Trijicon would change the color of the tritium, (green maybe) and that would help with the washout issue. It seems to have helped witthe ACOG's when they made the change.

I was shooting my dual-illuminated RMR on my FNP yesterday and didn't have any trouble with the reticle, even under the shade of the range canopy. I had an older Reflex that was horrible for that and have since sold but the RMR, in any model, is not a bad sight at all. I think it'll be fine for what you want.

Ahhhhh, the actual comparison. Glad to hear it. I really like the reflex site, but the wash out problem is a real concern, 'specially at nite. Might just have to try one of the RMR dual illum's.

Just curious, how is the RMR on an indoor range?

Haven't shot it at an indoor range but here in the house I haven't had any trouble picking up the dot at all. With the RMR being in constant co-witness with the sights on that particular pistol it's not much of a concern if it did wash out.

Thanks, sounds like they have improved it. Moving the light collector to the top probably helped a lot. I probably end up buying one sooner or later.
