Optic Review: Primary Arms Advanced Series Red-Dot Sight

[Zarvan]

Primary Arms, a popular online retailer of optics and gun accessories, introduced their own line of affordable optics a few years back. The Advanced Series is their full-size red-dot sight models. The OEM of the optic is actually Holosun and it’s made in China.

Some the features that caught my attention about this Primary Arms red-dot sight are its 50,000 hours battery life, it uses a common size CR123 lithium battery, 2-MOA dot and the included flip-up lens covers.

The Primary Arms Advanced Series red-dot sight is about the size of the Aimpoint Comp M4. It has an absolute co-witness height with its integral mount. As you can see that the Primary Arms magnifier at the back is setup for the lower 1/3 co-witness.

This top view shows the control of the Primary Arms Advanced Series red-dot sight. The “+” and “-“ button controls the red-dot reticle intensity. In front of those two buttons is the laser activation button, but my sample doesn’t have one. On models that have the laser designator, it’s just an additional module added in front of the battery compartment. The laser is available in red or the more expensive green version. However, the laser is not synced to the optic’s windage and elevation adjustment. The laser has to be zeroed separately with it’s own adjustment.

I am not a fan of the Holosun quick-detach lever that comes with the Primary Arms sight. It’s a bit chintzy for my liking and the latch locking mechanism is also rather unsubstantial. The lever itself seems to be just stamped from metal. Holosun has informed me that they are working on improving their QD lever design.

Overall, the Primary Arms Advanced Series Red-dot sight is a good optic for the money. Its 2-MOA dot is very bright and remains sharp even when see through a magnifier.
