What is the cowitness height?
Wldulikeaplpie on Nov 2, 2019
Will the riser mount clear an A2 front post?
thomas u on Dec 11, 2019
BEST ANSWER: The A2 sight is supposed to be centered in the lens. You should be looking through the rear aperture sight and see the red dot sitting atop the post. It is very fast. If the battery dies, you can still use your sights.
Are the lens covers tinted or clear? I can’t tell by the pictures.
Michael W on Mar 25, 2020
BEST ANSWER: Both covers are clear, and it is unnecessary to open the covers to shoot. You simply look through them. That is actually a real advantage over the red dots that have a lens cover that must be removed. Not only can you just pick it up and see, but the clear cover protect the lens. You simply clean the clear covers. I have had this sight for a while and it is now my favorite red dot. The color you see in the photo is the surface of the inner lens coating. There is no tint view when looking through the sight.
how far will the red dot be affective?
Henry S on Feb 27, 2020
BEST ANSWER: Affective ? unknown... Effective? Depends on a few factors 1. zero range, 2. ammo used, 3. your skill and experience, 4. weather conditions. As well as what Rogerthat said... as long as the battery is good..it can be effective.
Can it fit on the PSA 47 looking for the best close to mid ridge sight for it?
Nicholas W on Feb 29, 2020
BEST ANSWER: Not the best sight for an AK.
Is this both a Red Dot and Green Dot?
Dimyas on Nov 1, 2019
BEST ANSWER: Sig site lists 2 different models, one red and one green. SOR72001 is red.
Does the high rise mount allow the use of iron sights?
Dan B on Apr 26, 2020
BEST ANSWER: Yes. I use flip up iron sights and sighted in with no issues. I had it dialed in in about 15 minutes or less (with and without sites up). Time may very depending on the shooter and range condition
WIll this hold up to the recoil of an AR45?
TIMOTHY P on Feb 19, 2020
BEST ANSWER: It should, I installed on a typhoon 12guage and have shot over 100 slugs with it. No propblems
Would this site be good my AR 10.5 pistol?
Steaphon H on Apr 26, 2020
BEST ANSWER: That’s what I put mine on. A 10 in pistol . Works pretty good on that platform
What exactly does the 2MOA & the MSR in the name mean on the SIG SAUER ROMEO MSR 2MOA RED DOT, BLACK - SOR72001 ?
Jim on Mar 31, 2020
BEST ANSWER: The Red dot covers 2 minutes of angle. I assume the MSR refers to Modern Sporting Rifle given that is set up to co-witness with AR sights.
What magnifier would work with this Red Dot?
Tony B on Mar 8, 2020
BEST ANSWER: Sightmark XT3 worked for me, good price and alignment was perfect
How far out can you accurately shoot with the red or green dot ?
Alan M on Apr 24, 2020
BEST ANSWER: Well man, that all depends on you...If you shoot a 2 inch group at 100 yards, this dot is a 2MOA dot. so at 100 yards technically youll be able to group 4 inches. at 200 yards, 8 inches and so on...a accurate shooter with a good rifle could be effective with a red dot out to 400 or so meters. before we went to ACOGS in the Infantry we used CCO's which were aimpoints and reddots. We accurately used them on 300 meter targets all day and a further out in the field or on mission. Purpose of a red dot though is mostly close quarters quick target stuff. If you are wanting long range, I suggest looking into a ACOG
Will this fit on the PSA AK47 GF3?
Garrett C on May 9, 2020
BEST ANSWER: you will need a side mount rail to mount it to, or a ultimak rail. Also you'll need a low profile mount to attach it to that
will this fit on Glock 19?
Vinny on May 6, 2020
BEST ANSWER: NO! This RDS (Red Dot Sight) is meant to go on an AR Rifle or Pistol like AR15/AR10/AR9 with Picatinny Rail. If you’re looking for a Pistol RDS, look into Trijicon RMR, Holosun 407/507/508, Vortex Venom, Leupold Delta Pro and so on.
Can you take it off the riser block? Does it have screws that mount it to the riser block?
Nick M on Feb 19, 2020
BEST ANSWER: Yes you can. It uses the same basic T1 Micro(Aimpoint, Sig, Holosun) footprint. So any mounting system compatible with those should work. What are you trying to mount it to?
Will it mount to a hatsan 22 single shot pellet rifle mod 95 sas ?
Jeff H on May 7, 2020
BEST ANSWER: The mount is a high rise which I removed to fit on my Kel tec 2000. It appears to be a common mount fitting and could possibly be fitted to your rifle. A great Red Dot at a great price.
Can you remove the lens covers? Or can you turn them to lay down on the rail when open instead of up blocking your view above the sight. My romeo 4s covers can be turned down.
XFrog on Apr 12, 2020
BEST ANSWER: Yes, the lens covers rotate on the tube. You can turn them to open down or to the side. I have not tried to remove them, but they seem like you could.
Does anyone know if I can use any magnifier with this sight ??
Hunter C on May 6, 2020
BEST ANSWER: I have not tried that yet. But I see no reason why it should not
Will this hold up to a 45-70’s recoil?
Lpukas2 on Apr 25, 2020
BEST ANSWER: The ROMEO-MSR is a sealed compact red dot or green dot sight intended for MSR, carbine, shotgun and air rifle. Brightness is adjusted with a top-mounted rotary dial, featuring 10 daytime and 2-night vision settings for quick target engagement in any condition. If it works with shotguns it should be fine on a 45-70
Would this work for my M12AK ?
Ted R on May 30, 2020
BEST ANSWER: Ted yes it should work fine. So far I am very happy with the red dot I have it on my Sig MPX and have over 1,000 rounds through it and it’s great.
Marco Q on May 20, 2020
BEST ANSWER: Probably, I use a magnifier on my rifles. My Romeo MSR is
on an AR 9 pistol since it’s a 4.5” barrel it doesn’t need a magnifier.
Can this optic be mounted to the side of a variable power optic using a 45 degree mounting bracket?
Eric C on May 2, 2020
BEST ANSWER: Sure can, far as I know you can mount any red dot on a 45, these are awesome dots for 100 bucks, we have 3 on different rifles
Will this fit on a weaver rail?
Graham B on Apr 9, 2020
BEST ANSWER: I don't think it will. It's my understanding that picatinny accessories will not fit on Weaver rails but, Weaver accessories will fit on picatinny rails.
Good luck!
Will the battery really last over 3 years (20,000hrs) if I never turn it off?
Aktrite28 on Mar 23, 2020
BEST ANSWER: Interesting! Never thought just to leave it on. I purchased one for a second AR Pistol, but I use the Sig Romeo 5 on my primary AR Pistol as the Romeo 5 turns itself on and off automatically. So I actually recommend the Romeo 5.
Can I use this on my AR ?
Charles B on Mar 19, 2020
BEST ANSWER: You can. One answer already posted indicated that there are a certain kind of cowitness sights that you can use with this optic. In my photo on my 300 bulk pistol, I am using it with cowitness sights as well and it lines up nicely.
Work on kel tec sub 2000?
Mitch M on Mar 12, 2020
BEST ANSWER: Is perfect for PCC. As long as you have a pic rail for mounting.

Sig Sauer Romeo MSR 2MOA Red Dot Sight
I like it. Well made. Compact. Simple to operate. Great price compared to what others are selling it for. Very pleased.

Good to 100 yds.
I was wondering if this optic would be good enough to sight in at 100yds. It is shooting as good as I can see and I can hit a 3” bullseye most of the time at 100 yds. This is with Tula 55 gr. ammo in a PSA nitride barrel with mid length gas system. Happy so far.
May 31, 2020
Excellent optic for the money
Battery life is no joke. Left mine on for a week, still going strong.

Over all the optic isn’t bad. Bolt head stripped immediately when being tightened down.

Great price, great performance.
Glass is crystal clear. Flip up covers are a little stiff but I expect them to loosen up with use.

Works good on my Sub 2000.
Still new, so far so good. On my Sub 2000 with M*Carbo mount, red dot sits above factory sites. Was easy to zero in. Bright adjustment knob hard to turn maybe needs break-in.
