The Sig Sauer ROMEO5 Red Dot Sight 1x20mm 2 MOA provides a robust 1x aiming solution for any situation. The sights are parallax-free so point-of-aim and point-of-impact remain the same. Unlimited eye-relief allows you to acquire targets regardless of the position of your eye behind the sight. With up to 50,000 hours of life, the commonly available CR2032 battery is side loading so you can replace it quickly if it fails. Romeo5 also features MOTAC (Motion Activated Illumination), which will automatically turn on or shut down based upon the optic’s movement, increasing battery optimization even further. Sig Sauer makes this optic widely adaptable to various weapons with a M1913 Picatinny system, plus low mount riser and a co-witness riser mount allow the user to customize the view to their perspective.

Sig Romeo5 is THE AR Pistol Optic to Buy

by -

Grabbed another one of these red dots during the last deep discount, simply because for such a deeply discounted price, small footprint, battery life & feature rich optic, you can’t beat the value at 0 to 200m.

Have these mounted on 10.3, 11.5 & 12”” defense/work AR Pistols - fast target/dot acquisition, excellent accuracy, holds zero & you don’t have to worry about battery life. It will be there when you need it, and you’ll hit what you aim at when properly zeroed.

Wait until a deep discount sale & stock up - you won’t be disappointed.

Have not been to the range yet, but am impressed. The 2 MOA dot is a major plus. Shake and wake is a great feature.

Great lightweight red dot

by -

Put 120 rounds on it the day I got it, and it held up great. Comes installed on an absolute co-witness mount, with included compact mount in box along with adjustment tool, manual, and lens cleaning cloth.

I am sure it will hold up for years to come. 10/10

Nice dot

by -

Bought for trials on my Colt LE6920; works well, comes "to eye" very quickly and has held zero for 200 rounds so far.

Quality Red Dot

by -

Just another quality red dot from Sig. By far the best bang for your buck. Already have an MSR and bought this for the shake awake feature.

Best for ammo

by -

This is my third Romeo5. Hard to beat this optic, not just for the price but because it truly runs with other quality optics out there. But as for the price, it allows me to also get a little more ammo for my new builds too!
