Vortex Optics Defender-XL 8 MOA Red Dot Sight with Picatinny Mount
The Vortex Optics Defender-XL™ 8 MOA Red Dot Sight with Picatinny Mount is designed to dominate in dynamic shooting scenarios where speed, accuracy, and toughness are paramount. Unlike red dots made for competition, the Defender-XL™ thrives in real-world conditions, handling unexpected drops and the rigors of demanding shooting stages with ease. Its ultra-wide sight window provides an expansive field of view, ensuring rapid target acquisition, quicker follow-up shots, and versatility in unconventional shooting positions—empowering you to excel with every shot.
The Defender-XL™ is equipped with an 8 MOA daylight-bright red dot reticle, optimized for visibility in any environment. With 10 brightness settings, including two compatible with night-vision devices, the reticle performs seamlessly from daylight to low-light scenarios. Its motion activation system ensures the sight is always ready when you are, while a 10-minute auto-shutoff feature preserves the CR2032 battery, providing an impressive runtime of up to 25,000 hours.
Durability is at the forefront of the Defender-XL™ design. A rugged 7075 aluminum chassis reinforced with ShockShield™ polymer inserts protects the optic from impacts and everyday abuse. The Fast-Rack™ texturing on the face of the sight allows for confident racking off any surface, even in high-pressure situations. Waterproof, fogproof, and finished with a low-glare matte black anodization, this optic is built to perform reliably in any environment, resisting corrosion, dust, and debris.
Practicality meets precision with the Defender-XL™. The top-mounted battery compartment enables easy replacement without the need to re-zero the sight. A parallax-free design and unlimited eye relief make target acquisition instinctive and effortless, while precise adjustments—1 MOA per click with a maximum elevation of 120 MOA and windage of 115 MOA—ensure you can dial in your shot with confidence. Its large, distortion-free lens delivers a crystal-clear sight picture, further enhancing accuracy and confidence in every scenario.
The Defender-XL™ comes complete with everything you need to get started: a Glock MOS adapter plate, Picatinny rail mount, rubber cover, lens cloth, a battery, custom tool, and five sets of common mounting screws. Compact, lightweight, and engineered for peak performance, the Defender-XL™ is the ultimate red dot sight for shooters who demand speed, reliability, and precision in any situation.
