Sig Sauer ROMEO4S 1x 20 mm Tactical Solar Powered Shooting Targeting Waterproof Closed Red Dot Sight

I use this on a FX-9 9mm carbine. I really like the 1 moa duplex sight.

This sight came EXACTLY as advertised. Neatly packed in its original box. Complete with all tools, paperwork, battery, manual etc. Mounted to my AR with zero issue. Will zero asap.Update 02/25/20:I am SO glad I bought this sight. Even though it has four reticle choices, the "Quadplex" is admittedly my favorite. As light as this optic is, it is tough as a box of rocks too. Between this and a CMC trigger, it is an absolute pleasure to shoot and a destinctly unfair advantage over everyone I shoot with.May 21st, 2020:So, I added a Vortex 3 times magnifier to my set up and to my great pleasure, the magnifier and my Romeo work outstanding together. Now I can hit just as accurately and just as fast at 100yrds as I could at 25.PS- they aren't kidding about battery life either. Bought, this optic late last year and it's still on that same battery and going strong.

I've tried a half dozen red dot sights for my DDM4 V11 PRO and this is the best one of the bunch. Easy release QD mount and accurate. Was able to put 45 rounds in a 1.5" circle at 50 yards after zeroing in. Clear reticle covers are fantastic and is a much more robust option than the Romeo5. You will not be disappointed in the quality and accuracy. Also nice option to have the circle plex reticle or red dot.

I purchased this red dot to put on a light weight short to medium range Hunting rifle. I sited it in at 200 yards and have shot about 40 rounds through it so far and it is holding zero nicely. The only thing stopping me from shooting a tighter grouping is the fact that the + reticle obstructs the entire center of the targets I was using at the 200 yard mark. At 100 yards I was able to place shots on top of shots multiple times and maintain 1 moa accuracy. The only issue I had with this optic which is no fault of sigs was that the mount would not fit the rail on my Steyr. I contacted Sig Sauer support for some advise and they were very helpful! They let me know that Aimpoint T1/T2/H1 mounts were fully compatible with the Romeo4. So I was able to find a nice BoBro low mount that had a keyed lug that I was able to remove, file down to weaver spec and re-assemble. I also like the clear lenses that can be left up in bad weather for shorter range engagements. They are a little stiff and not easy to flip down (like butler creeks) but that should not be an issue for me.

Excellent SIG quality red dot. QD fits perfectly. 4 different reticles can’t beat that. Plus solar great deal.My 2nd one. Highly recommend even better when paired with JULIET magnifiers.Yes it does work with A2 setup if you ignore front sight post in CQB red dot mode. When magnified front sight post is a distant blur. Won’t even know it’s there.

I recently purchased this Sig Sauer Romeo 4 for my AR15 6.5 Grendel but after mounting it and getting ready to he'd to the range. I turned it on and it only had 2 of the 4 reticles working. However, I already had one for my other S&W AR15 so I know they work very well. Looking forward to getting a refund and reordering the replacement.

Mounted this to a .308 with a Sig red dot magnifier. In magnifier mode it works much like a scope and the 1moa dots and hairs help to consistently hit the 300 yard plate at the range. Up close without the magnifier its easy to hit a nice small bullseye at 50yards. The Quadplex reticle with bullet drops really makes this a versatile setup for up close and far away shots.

Very solid product all around. Easy to install, easy to see even with my bad eyesight, and easy to dial in. Would recommend to anyone looking for a midrange priced red dot.
