DESCRIPTION

The Vortex Optics Defender-XL™ 5 MOA Red Dot Sight is engineered for shooters who demand performance under the most rigorous conditions. Built to dominate competitive shooting scenarios, the Defender-XL™ offers a perfect blend of toughness, speed, and accuracy. Its robust 7075 aluminum body, fortified with ShockShield™ polymer inserts, shrugs off the impacts of unexpected drops and everyday abuse. Whether you're transitioning between targets or pushing through dynamic stages, this optic is your ultimate ally.

At the heart of the Defender-XL™ is an ultra-wide, distortion-free aspherical lens that delivers a crystal-clear sight picture, ensuring rapid target acquisition and precise follow-up shots. The large sight window (25.5mm W x 23.3mm H) enhances peripheral awareness, granting greater flexibility when engaging in unconventional shooting positions. Paired with a bright 5 MOA red dot and 10 adjustable brightness settings, the reticle remains sharp and visible in all lighting conditions, including two settings compatible with night vision.

Designed for practical use, the Defender-XL™ features a motion-activated reticle with a 10-minute auto-shutoff to preserve its impressive 25,000-hour battery life. The top-mounted CR2032 battery can be replaced without the need to rezero, streamlining maintenance. Its Fast-Rack™ texturing allows for confident racking against any surface, while Picatinny mounting ensures compatibility with a wide range of platforms. The optic's single-piece chassis is lightweight at just 1.93 oz and sports a low-glare matte black anodized finish for durability and stealth.

The Defender-XL™ excels in all environments with waterproof, fogproof, and corrosion-resistant construction. Its parallax-free design and unlimited eye relief ensure seamless performance, while the included Glock MOS adapter plate, Picatinny rail mount, rubber cover, lens cloth, battery, custom tool, and mounting screws provide everything you need for a quick and secure setup. With its rugged reliability and superior functionality, the Defender-XL™ is the red dot sight you can trust to outlast and outperform.
