Because precision and durability are paramount when it comes to hunting and tactical gear, the 1x21 S3 Series Red Dot Tube Style Sight, with its 2.5 MOA Red Dot Reticle, is designed to exceed your expectations. Whether mounted on a shotgun for turkey hunting, a rifle for big game pursuits, or a pistol or tactical rifle, this Styrka S3 Red Dot Sight is engineered to deliver superior performance.
Constructed from 6061-t6 aircraft-grade aluminum, this sight offers the perfect blend of strength, durability, and lightweight design. Its double-lens optical system, enhanced by dot color indexed coatings, virtually eliminates parallax and point-of-aim errors, ensuring your shots are accurate every time.
The tube design of this red dot sight features a smaller dot to minimize target coverage, enhancing your precision. With six adjustable brightness settings, you can easily adapt to changing light conditions for optimal visibility. The unit also features an auto shut-off function that activates after one hour of inactivity, preserving your battery life. Plus, the last-setting return feature ensures the unit automatically reverts to your last used brightness setting.
For quick and easy target acquisition, this sight offers unlimited eye relief. The integrated turret adjustment tool, conveniently built into the top of the turret caps, is always at your fingertips when you need it.
Designed to withstand all conditions, this 1x21 S3 Series Red Dot Tube Style Sight is 100% waterproof. It has been submersion tested for 30 minutes in 1 meter (3.3 feet) of water, proving its resilience. The internal housing is nitrogen purged, replacing air with dry nitrogen gas to prevent internal fogging.
Your purchase includes a high-rise mount for firearms requiring additional height for correct red dot viewing. A honeycomb filter is also included to reduce glare and reflection from the objective lens. To protect your lens from scratches and block dust, dirt, and moisture, a custom Styrka neoprene cover is provided. Additionally, a genuine Spudz lens cleaning cloth is included for quick and convenient cleaning in the field.
