The SIG Sauer Romeo-MSR Red Dot Sight is highly versatile and compatible with a wide variety of firearms including the MSR, carbines, shotguns, and even air rifles. It is a fully sealed design made from aluminum making this an extremely durable option for any use case. The protected emitter projects a 2 MOA red dot for quick and precise shooting. The top mounted rotary dial allows you to quickly switch between 10 different brightness settings and 2 night vision settings. The battery compartment is also located in the rotary knob for easy access and runs for about 20,000 hours on a CR1632 battery. The lenses are fully coated for optimal light transmission and clarity and like most red dots has unlimited eye relief and zero parallax. Additionally, it comes with see through flip up lens covers for added protection during storage. Another bonus of this red dot optic is that it comes with a skeletonized lightweight riser mount set for an absolute co-witness with iron sights.

great dot sight

by -

I decided it was time for an upgrade to newer technology and this little gem from SIG came along with a great price. Compact, light in weight and easy to mount
<br>with the included torx wrench. Until now I had one of the original Tasco dot sights mounted on my AR.
<br>Outstanding performance on the range also.

Best budget value red dot

When I need a go to, simple, and very cost effective red dot optic I turn to the Sig MSR. The size is perfect, applications are endless, and I don’t think there’s a better performing, feature packed red dot on the market for the money. Especially at $89 on sale at Primary Arms! Thanks!

Great bang for the buck

Install on a 10in rifle and was within 2in of being zeroed at 36yards have no complaints currently

Love it

by -

Caught these on a hell of a sale, just wish I'd bought more.

It'll do what I need

Attachment is sturdy. Flip up end caps hard to close. Seems adequately bright. Worth the discounted price.

Quality at a good price.


Well worth the $89.00. I zeroed it in a few minutes and it’s hold it accuracy well so far. Seems durable and even looks cool. I love the flip up/down lens covers, but they are tight as hell don’t expect to flip them up and down quickly. I always just leave them down. IMO you just can’t beat the quality of this red dot for this current/sale price. I bought 2 already and may go for a 3rd.

Worth the money!

Missed the sales before and glad i did. 81 bucks shpd. Received four days after placing order! Awesome combo for magpul flip-ups! 1.41 co-witness works for me. Crisp Dot. Only covers about a third of the black on a ten inch target at 200 yds. Catch it on sale and have fun at the range getting zeroed again! Yeh stuff is tight now, it's new. Better than loose, and flying off.

Great as a backup

by -

Meets my needs and still has a lifetime guarantee. Can’t beat the price.

Small but effective

by -

Bought it for my 16" AR-15 but was small so instead instead installed it on my AR-9 pistol

It’s a Sig, to hell and back reliably?

I really like Sig products, always great right out of the box. The Romeo MSR is no exception!
