Mission First Tactical
Overview
The Mission First Tactical AR-15 Rear Sight features a flip-up design, allowing for quick deployment and a low profile when not in use. Its black color complements various builds while ensuring durability in the field. This rear sight is commonly found in mid-length gas system builds, particularly those chambered in 5.56 NATO, making it a practical choice for shooters looking for reliable sighting options.
Mission First Tactical AR-15 Rear Sight Flip Up Polymer Black was the fourth most added rear sight on GunPartPicker in August 2026, behind the Magpul MBUS Gen 3 Folding Rear Sight - Black, with about 10% of all rear sights added to builds.

polymer rear sight, fold mechanism is positive with detent click. windage adjustments held zero through 200 rds. apertures are sized right for both close and 200 yd irons work. cheap, light, and functional
auto brightness works as expected and the battery life is way better than my old red dot
