Does this come with the flush rail mount as well?
Todd M on Jun 16, 2018
BEST ANSWER: Mine did not, only the mount that aligns with standard height iron sights.
Would this be a good fit for an AR platform?
Lance O on Jun 14, 2018
BEST ANSWER: Yes it comes with a great qd high rise mount that cowitnesses with AR iron sights. It has beautiful glass and a nice window size.
What's the difference between SOR31099 and SOR31002? Which is the latest?
Jeremy H on Jul 1, 2018
BEST ANSWER: SOR31002 is the version in the retail box with all mounts, and of course not on sale anywhere. SOR31099 is the OEM version shown above that just comes loose in a parts bag, with no low mount. Good luck trying to find a low mount. Even Sig won't sell you one... At least as far as I've been able to find in my research. There are other mounts it will for on but overhangs the mount on the front.
Does this have the same footprint as the RMR?
Nathan C on Jun 13, 2018
BEST ANSWER: No. This is a Medium size optic that uses the same mounting footprint as the Cmore RTS2 or the Vortex Razor, but is a bit longer front and back then either of those other models.
Will this fit a Sig Sauer p320 compact 9mm ?
Big man on Jun 17, 2018
BEST ANSWER: Please see above answer that I posted. After looking at the P320 that my buddy has and my Romeo 3 there is physically no sensible way to mount that optic to the slide without going with a rear sight dovetail mount which will overhang the back of the slide and you will lose your rear sight by installing the mount. In terms of milling it into the slide, maybe once again if you completely milled the slide from the breech face all the way back removing the rear sight dovetail in the process. The Romeo 3 is really too large in general dimensions (60mm front to back) and weight to be using for slide mounting. Sig installs the Romeo 1 on their P320rx, if you are wanting to slide mount a sig brand optic that is the one I would suggest as it is 45mm from to back.
Is it a good sight for range targeting up to 500 meters ?
robert o on Jun 19, 2018
BEST ANSWER: Past 100 meters I would want a regular rifle scope with good magnification.
Does it come with any type of protective cover for when it is not in active use?
Michael on Nov 6, 2018
BEST ANSWER: Yes, it comes with a huge cement brick and a bungee cord you can install over the sight system.
Optional carabiner & lanyard makes carrying it along with you easy.
;) wondering if PSA reads these, seems they don't have time to answer regular inquiries.

Daniel Defense Fixed Front/Rear Sight Combo 19-088-09116
Daniel Defense Fixed Front/Rear Sight Combo 19-088-09116
BEST ANSWER: Yes, it should. I put pictures in my review below. Picture is on a Sig MPX, but flip up sights should be standard. I measured (caliper) top of front post to center-line of barrel at 2.92 inches.
Is this made in the USA?
Melfred R on Jun 19, 2018
BEST ANSWER: I would call Sig to see where it is actually put together vs. actually manufactured.
Does it come with any type of protective cover for when it is not in active use?
Michael on Nov 6, 2018
BEST ANSWER: Yes it comes with a rubber cover, the sight overall is a nice piece! I put it on my MPX and it’s like they were made for each other.
Can I detach the high rise mount from the Romeo?
Steven Q on Nov 21, 2018
BEST ANSWER: Yes. I bought three Romeo 3's. Two I used the high rise mount on AR-15s. The third I ordered a low mount on line and removed the high rise mount. You can change the mounts out.
Does it come with the low mount as well?
Ray77nik on Nov 19, 2018
BEST ANSWER: No. The mount pictured is how it comes. Great sight too! Works great on a flat top AR.
It's this red dot tough enough for a Mossberg 590 a1 recoil ?
W. V on Sep 24, 2018
BEST ANSWER: It works on my em-12B semi auto without any issues. So I assume so
How long is battery life? Does it have any night vision settings.
Jackson on Sep 24, 2018
BEST ANSWER: Battery is about a week on the medium setting,night vision cost more than 250$ so no.
Sig P320 Compactc. Can this be used on a P320 compact with no rail on slide?
Ron T on Jun 16, 2018
BEST ANSWER: If you are planning on using this for USPSA carry optics division or range use it is possible by removing the standard optic mount, the rear sight on the gun and using a dovetail optic mount like egw or some other manufacturers make. Be aware you would no longer have a rear sight going this route, and I wouldn’t personally do that for carry. Size wise this optic is a bit on the too large size for slide mounting in my personal opinion. I am running one frame mounted on an open race gun and it’s ideal for that or for Tactical rifle use. I don’t know if it could be milled into the slide or not and be able to keep a rear sight for cowitnessing, but the optic is noticeably longer front to back than the vortex razor and Cmore RTS2 which it shares the same footprint style with and which would already be considered on the large size for slide mounting. Hope that helps.
will this mount to a gen 4 glock accessory rail? love sieg sawyer!
jim shawny on Oct 25, 2018
BEST ANSWER: An accessory rail is what is underneath the barrel and you would not be able to see the sight. I think what you mean to say is "Will it mount to a slide that has an RMR cut?" which is where the rear sight would normally be found. If that is the case, then no it will not fit unless you find a different mount system. also you would have to unscrew this sight from the base because it is too large. This system is designed for AR or AK with the rail on top or any other rifle based platform that accepts this type of mount. Like the CZ Scorpion.
Compatible with other mounts?
Would like a 1/3 cowitness
John S on Dec 16, 2018
Does this come brand new in the box exactly is shipped by Sig? I see that someone said it came in a plastic bag every other Sig Romeo I have purchased has come in the gray box With all the accessories
Bob M on Nov 20, 2018
Does it have a hard off switch to prevent vibration/motion from activating the MOTAC while it's in the truck?
orionsrevenge on Nov 19, 2018

Very Nice Red Dot for the Price
This is an unqualified review as I have not fully "torture tested" this sight for reliability, but from what I've seen, it's a pretty decent sight.

On the plus side, it gives a very clear, unobstructed field-of-view, and a nice, bright (adjustable) dot. Some Red Dot sights are like looking through a paper-towel-tube, but this one keeps the field of view pretty unobstructed, which I like a lot. And it's very light weight, which is also a big plus for anyone who wants to keep their system as light as possible.

On the down-side, it did not come even remotely zeroed from the factory. But if you run it in-between already zeroed Iron Sights, which I say you should, then it's a ~5 minute job to get it on target.

Again, I don't know how it will hold up over time, but so far I like it. And for the price, I would recommend picking one up. In fact, I might just pick up a second one!

My Favorite Red Dot Sight
These sights are awesome. Lots of different brightness settings, easy side battery slot, long life and of course the motion detection ON switch. What else do you need in a red dot sight?

Took a beating and keeps on pointing!
Placed on my B&T GHM9 which took a fall with me. Fall was hard enough to scratch up my watche’s sapphire crystal and knock off the WML. Stayed intact and kept zero.

It's made in Japan, not China if that matters to anyone. I found the quality to be very good.
