DESCRIPTION

The Vector Optics Frenzy 1x20x28 RD (TEK) Red Dot Sight is a compact, high-performance optic designed specifically for pistol platforms, offering a perfect balance of speed, precision and durability. Built from 6061-T6 aluminium alloy with a scratch-resistant matte finish, it delivers a robust yet lightweight construction suited to demanding use. Its extra-large 20x28mm viewing window and 3 MOA red dot reticle provide fast, intuitive target acquisition while maintaining excellent precision at typical engagement distances.

Engineered for reliability in all conditions, the Frenzy features a fully sealed emitter with an IP67 waterproof and shock-resistant rating, ensuring dependable performance in wet or harsh environments. The optic offers 8 daylight brightness levels plus 2 night vision-compatible modes, allowing seamless adaptation to changing light conditions. The reticle benefits from premium multi-coating and anti-reflective treatment, delivering a clear, vivid sight picture with reduced glare and improved contrast.

Powered by a single CR2032 battery, the sight provides long operational life with an efficient power system and an automatic shut-off function to conserve energy during inactivity. Designed with practical usability in mind, it features audible mechanical click adjustments with a ±1 MOA parallax correction for consistent accuracy. The Frenzy is supplied with a Weaver/Picatinny mount, protective lens cover, hex keys and a cleaning cloth, making it a complete and ready-to-use red dot solution for modern pistol setups.

The red dot appears as a blur / line. What is wrong?

-Lower the power of the dot, you will find the lower power settings will help with the blurriness / lines. Imagine starting into high beam LED headlights, it is the same effect.

What does MOA mean for the size of the dot?

-MOA means the amount of space the dot will take up at 100yds. Eg, 3MOA = 3 inches, 6MOA = 6 inches.
