The Vortex Optics StrikeFire® II Red/Green Dot Sight (SF-RG-501) delivers fast target acquisition, rugged reliability, and versatile performance at an exceptional value. Designed for shooters who demand speed and simplicity, this 1x red dot optic features a 4 MOA dot with selectable red or green illumination and 10 brightness settings, including night vision-compatible levels for low-light environments.

Built around a 30mm tube design, the StrikeFire II provides a wider field of view compared to micro dots, making it ideal for AR platforms, shotguns, and defensive carbines. Fully multi-coated lenses maximize light transmission and clarity, while the parallax-free design and unlimited eye relief allow for rapid engagement with both eyes open.

Constructed from durable aluminum with a hard-anodized finish, the StrikeFire II is engineered to withstand recoil, impact, and harsh conditions. Its nitrogen-purged, O-ring sealed housing ensures reliable waterproof and fogproof performance in any environment.

This model includes a cantilever mount for lower 1/3 co-witness, positioning the optic at the ideal height for modern AR-15 setups. Additional features like flip-up lens covers and a 12-hour auto shutoff enhance usability and battery efficiency in the field.

Whether you're upgrading your range rifle or building a dependable defensive platform, the StrikeFire II offers proven performance backed by Vortex’s reputation for durability and value.
