The Romeo5 is a small and compact sight with incredible yet simple features. It combines the Sig built-in MOTAC™ (Motion Activated Illumination), a system that shuts down when the sight has been inactive for 10 minutes and reactivates upon sensing movement. The reticle selector has two choices 2 MOA Dot / 65 MOA Circle option. The power source provides 10 brightness levels, 8 for daylight and 2 for nighttime, and lasts for up to 40,000 hours in the middle setting.

The Romeo5 comes with an ultra-low parallax. This delivers a point-of-aim is point-of-impact performance. The MOTAC provides automated brightness adjustment, this is an important feature because it allows you to manage the sigh hands-free, the MOTAC adjusts the brightness to the ambient lighting of your surroundings. You can go manual; all you need to do is deactivate the MOTAC this action gives you the best of both worlds.

The red dot and reticle are clear in all lighting conditions and the optics deliver a crisp and high definition picture of the target area. Together with the life of the battery, you get a constant and accurate service from this small sight.

Review

The Primary Arms Silver Series Advanced Push Button Microdot Red Dot Sight is a Silver Series™ optic that is considered the heart of the Primary Arms models. This is an SLx optic that is known to all Primary Arms users, and for those that don’t know if you are getting a high grade, high-quality sight with a few features more than its competitors in the same price range. With this said, let’s take a closer look to ascertain all of its qualities and features.

Primary Arms MD-ADS

This model comes with the standard single-cell CR2032 battery that provides around 50,000 hours of power when set to medium lighting level. This model comes in a high-grade aluminum alloy (6061 if that means anything to you) and is nitrogen purged to provide constant fog-proof performance. The body is also designed to provide a waterproof performance but can only go down to 6 feet, and the turret caps must be secured in place.

Primary Arms MD-ADS

The reticle and red dot are crisp, this sight provides a 2 MOA reticle and comes with an adjustment knob that can be click turned per 0.5 MOA. The push-buttons are located on the top of the sight, and you can set up to 12 different brightness levels manually. The optics are multi-coated, and there is no parallax shift after 33 yards.

Primary Arms MD-ADS

The chassis comes with a removable Picatinny rail mount, and it comes with compatibility for a standard micro mount giving co-witness capabilities.

Conclusions

When testing both sights, I found that the Primary Arms red dot model performs admirably, but it does falter in the rugged area, where it can be slightly soft when compared to the Romeo5. It is accurate and does provide manual zero adjustments with 12 illumination settings, but since it is not an automated sight, the need to play with the brightness can be compromising in short action-filled instances. The Rome5, on the other hand, provides fewer adjustment features but slams home the automated illumination and is a much more rugged sight.

The bottom line is that both are great sights, the Romeo5 is combat-ready, so you can use this in any instance and is considered a SHTF sight for all occasions, even though it is the simplest of the Romeo series. Against this stands the Primary Arms which provides a more manual approach, gives the same lifetime for power but is not the sight you want in combat, essentially this is a perfect target practice sight and one you would use in training sessions or at the range.
