Sightmark Core Shot A-Spec FMS Reflex Sight 1x 28x18mm 5 MOA Red Dot - Matte Black

The Sightmark Core Shot A-Spec FMS reflex sight delivers fast, both-eyes-open aiming in a compact, mid-sized package designed for rifles, shotguns, and similar rail-equipped firearms. Pairing a true 1x sight picture with a crisp 5 MOA red dot reticle, this A-Spec FMS fixed-mount optic is a versatile fit for competition shooting and hunting.

The housing is machined from aircraft-grade 6061-T6 aluminum and finished in a low-glare matte black coating, keeping the optic light at just 4.40 oz while standing up to hard recoil and rough field use. The rectangular 28 x 18 mm objective window provides a generous field of view, and the multi-coated AR Red lens treatment enhances reticle contrast against a wide range of backgrounds. At 2.30" long, the Core Shot A-Spec FMS adds minimal bulk to any platform.

Digital push-button controls cycle through 8 daytime brightness levels and 2 night vision-compatible settings, so the dot remains usable from bright sun to NVDs. Slotted windage and elevation turrets allow precise 1 MOA per-click zeroing, and unlimited eye relief lets the shooter mount the optic anywhere behind the ejection port and still get a full, unobstructed sight picture. The sight is powered by a common CR2032 battery and is rated water resistant and shockproof for dependable performance in real-world conditions.
