Vector Optics Frenzy FM 1x20x28 3 MOA Red Dot Sight

This optic is a Hi-Capa's best friend but is equally at home on an SMG, AR, shotgun or any platform with a Picatinny rail. Its lightweight, compact design makes it an excellent choice for builds with limited rail space, adding very little extra weight while still providing a generous viewing window. Looking through the multi-coated, lightly tinted lens provides a clear sight picture, while the crisp 3 MOA red dot allows for fast target acquisition and precise aiming in dynamic skirmish environments.

Surrounding the lens is a robust aluminium protective hood designed to absorb the knocks and scrapes that inevitably come with regular Airsoft use. Rather than risking damage to the lens itself, accidental impacts are more likely to mark the durable outer housing, giving you extra confidence when diving into cover, negotiating tight CQB environments or transporting your rifle between games. It's reassuring protection for any player who wants to keep their optic looking and performing its best.

The Frenzy FM is packed with premium features. Its parallax-free design helps keep the point of aim consistent, even if your eye isn't perfectly centred behind the sight, making target transitions quicker and more forgiving.

The crisp 3 MOA dot strikes an ideal balance between speed and precision, remaining easy to acquire without obscuring smaller targets at longer distances. For users running night vision equipment, two dedicated NV-compatible brightness settings ensure the dot remains visible without overwhelming image intensifiers.

The large viewing window provides an open sight picture that makes tracking moving targets easier, while the IPX6 water resistance means the optic will continue performing in heavy rain and wet skirmish conditions. Built with a rugged internal design, the sight is also shock-resistant enough to withstand the recoil of real firearm calibres, demonstrating the durability and reliability of its construction.

The Vector Optics Frenzy FM 1x20x28 3 MOA Red Dot Sight requires a single CR2032 battery to power the illuminated reticle. Once installed, brightness can be adjusted using the buttons on either side of the housing, with eight daylight brightness levels available alongside the two dedicated night vision settings. Holding both buttons simultaneously powers the sight off, helping preserve battery life when the optic is not in use.

The button on the left side increases brightness, while the button on the right decreases it. When you reach the lowest visible brightness level, pressing the right-hand button once more will switch the optic off completely, making operation intuitive without navigating complicated menus.

Windage and elevation adjustments allow you to zero the sight so your point of aim matches your BB's point of impact. Using the included Allen key, elevation can be adjusted via the grub screw at the top rear of the sight. Rotating it clockwise moves the point of impact upwards, while turning it counter-clockwise lowers it, allowing precise adjustment to suit your chosen platform and engagement distances.

Windage adjustment is located on the right-hand side of the sight and works in much the same way. Turning the adjustment clockwise moves the point of impact to the right, while counter-clockwise shifts it to the left. Fine-tuning both adjustments ensures your optic is perfectly zeroed, helping you make the most of the Frenzy FM's precise 3 MOA aiming point.

Included in the box is a Picatinny rail mount, allowing the sight to be installed straight onto a huge range of Airsoft replicas without the need for additional accessories. Using the supplied star-shaped Allen key, simply loosen the mounting screw, slide the optic onto your Picatinny rail, position it where desired and tighten it securely for a solid, reliable fit that will stay put throughout demanding skirmishes.

The sight uses the TEK™ footprint, making it compatible with mounts that follow the popular Docter/Noblex® mounting standard. This broad compatibility makes it easy to install on pistols, offset mounts or alternative mounting solutions designed around the same footprint, giving you plenty of flexibility when configuring your setup.

Combining premium construction, practical features and an exceptionally compact form factor, the Vector Optics Frenzy FM 1x20x28 3 MOA Red Dot Sight is an outstanding choice for any Airsoft player. Whether you're building a lightweight Hi-Capa, a fast-handling CQB SMG or a full-sized rifle, it delivers rapid target acquisition, dependable durability and the premium feel expected from Vector Optics.
