Primary Arms SLX MD-20 Red Dot Sight

1. Rugged Enclosed Design: The SLX MD-20 features a tough, 6061-T6 aluminum housing that fully encloses the emitter. This design provides superior protection against the elements, dust, and debris, making it incredibly durable for hunters and tactical users who operate in demanding environments. Its robust construction ensures reliable performance even under harsh conditions and significant recoil.

2. Extended Battery Life & NV Compatibility: With an impressive battery life of up to 50,000 hours from a single CR2032 battery, the MD-20 ensures prolonged field use without constant battery replacements. It also includes 2 night-vision compatible settings, allowing seamless integration with NV devices for low-light operations, an essential feature for both tactical applications and nocturnal hunting scenarios.

3. Versatile 2 MOA Dot Reticle: The crisp 2 MOA red dot reticle offers a perfect balance of precision and speed for rapid target acquisition. It's fine enough for accurate shots at various distances but large enough to quickly pick up in dynamic shooting situations. This versatility makes it ideal for AR rifles, PCCs, and shotguns, catering to sport shooters, hunters, and tactical operators alike.

4. Aimpoint Micro Footprint: The MD-20 utilizes the widely popular Aimpoint Micro footprint, providing unparalleled versatility in mounting options. This allows users to easily interchange the included low Picatinny mount with a vast array of aftermarket mounts, including those for pistols or high mounts for co-witnessing with iron sights on AR platforms, ensuring optimal eye relief and positioning.
