The Sightmark Strikon FMP 1x18 is a compact, high-performance prismatic sight built for fast-paced shooting scenarios where clarity, speed, and ruggedness matter. Unlike reflex or holographic sights, the FMP uses an etched reticle and internal glass prism, delivering a crisp, parallax-free image with zero dependence on a powered emitter. Even with the battery dead, the reticle remains visible - making it a smarter, more durable alternative to standard red dots. The FMP utilizes the RTR-1 (Rapid Targeting Reticle), designed to provide fast sight alignment and accurate shot placement. The reticle is illuminated red or green with 12 brightness levels with 3 for night vision use, and is powered by a single CR2032 battery. Runtime ranges from 100 hours on high to 10,000 hours on low, with a Shake Awake function that deactivates the unit after 10 minutes of inactivity and reactivates it after the slightest movement. This optic is also equipped with automatic brightness adjustment capability, optimizing illumination based on ambient light conditions. Built on the AimpointA(R) Micro footprint, the FMP includes a 0.39" riser (1.54" centerline height) and multiple screw sets for height customization. The flush adjustment turrets eliminate snag points and preserve a slim, snag-free profile - perfect for duty use or tight gear setups. With 3.85" of eye relief, 16.4 degree angular field of view, and an 86.5 ft @ 100yd FOV, the FMP gives shooters a wide, comfortable window for both-eyes-open shooting. The optic is IP67 waterproof, shock tested to MIL-STD-810H, nitrogen-filled, and built from durable 6061 aluminum. Fully multi-coated lenses ensure efficient light transmission and sharp image resolution. Whether you're upgrading a patrol rifle, building a do-it-all AR, or replacing a fragile red dot, the Strikon FMP 1x18 delivers clarity, reliability, and speed, on or off the grid.
