The Xoptek Micro Red Dot Sight (part number XOPTEK-RD-03A, UPC 666595000995) is a 1x open reflex red dot sight with a 3 MOA red dot, supplied on a Picatinny mount. It weighs 37 g, measures 46 × 38 × 25 mm, holds parallax under 1 MOA, offers 60 MOA of windage and elevation adjustment, and runs up to 34,000 hours on one CR2032 cell. This listing is for the sight only, supplied without its retail box.
A 3 MOA dot is the general-purpose choice: fine enough to shoot precisely at 100 metres, big enough to find instantly at conversational distance. At 37 g the Xoptek Micro adds almost nothing to a rifle, which is the point of a micro reflex — it is an inexpensive way to turn iron sights into a both-eyes-open sighting system.
How It Compares
The Xoptek Micro is the value entry point in our red dot range. For a duty-grade micro dot with motion-activated illumination, compare the Primary Arms SLx MD-21 2 MOA red dot sight, or step up to the solar-backed Primary Arms GLx MD-21S 2 MOA red dot sight. If a red dot looks smeared or starburst to you, a prism scope may suit your eyes better — see our prism scope range and the guide to red dots and astigmatism. Browse the XOPTEK range, all red dot sights, and read our guide to the best budget red dot sights and the red dot size chart.
