Description
This optic is a Hi-Capa's best friend, but it's equally at home on an SMG, AR, shotgun or any Airsoft platform equipped with a Picatinny rail. Thanks to its lightweight, ultra-compact design, it's ideal for builds with limited rail space, adding minimal weight while still offering a generous viewing window. Peer through the multi-coated aspheric lens and you'll be treated to a crisp, distortion-free sight picture, complemented by a sharp 3 MOA red dot for rapid target acquisition and precise aiming.
Protecting the lens is a rugged 7075 aluminium hood, built to shrug off the bumps and scrapes that come with regular Airsoft use. Whether you're diving into cover, squeezing through tight CQB spaces or transporting your replica between game days, the durable housing is designed to take the knocks before the lens does, helping keep your optic protected and performing at its best.
Packed with premium features, the Frenzy-X FLEX is designed to perform in demanding conditions. Its parallax-free design helps keep your point of aim consistent, even if your eye isn't perfectly centred behind the optic, making fast target transitions more forgiving. The large viewing window provides an open sight picture for easier tracking of moving targets, while the crisp 3 MOA dot balances speed and precision without obscuring smaller targets at longer ranges.
For those running night vision equipment, the sight includes two dedicated NV-compatible brightness settings, alongside nine daylight brightness levels to suit everything from dark indoor CQB sites to bright outdoor skirmishes. Rated to IPX7 water resistance, the Frenzy-X FLEX is ready for heavy rain and wet game days, while its robust internal construction is shock-resistant up to 1000 G, demonstrating the durability expected from a premium Vector Optics sight.
Power comes from a single CR2032 battery, with brightness adjustments controlled via the buttons on the left-hand side of the housing. The plus button increases brightness, while the minus button reduces it through the available settings. Holding both buttons simultaneously switches the sight off, while pressing the minus button again from the lowest visible brightness setting also powers it down, making operation simple and intuitive without the need to navigate complex menus.
To ensure maximum accuracy, the Frenzy-X FLEX features fully adjustable windage and elevation controls, allowing you to zero the sight to your chosen platform. Elevation is adjusted using the grub screw at the top rear of the optic with the supplied Allen key. Turning it clockwise raises the point of impact, while turning it counter-clockwise lowers it.
Windage adjustment is located on the right-hand side of the sight and is adjusted in the same manner. Rotate the adjustment clockwise to move the point of impact to the right, or counter-clockwise to shift it to the left. Once zeroed, you'll be ready to take full advantage of the optic's fast and precise aiming capabilities.
Included in the box is a Picatinny rail mount, allowing the sight to be fitted straight onto a huge range of Airsoft replicas without the need for additional accessories. Simply loosen the mounting screw using the supplied star-shaped Allen key, slide the optic into your preferred position on the rail and tighten it securely for a rock-solid fit that will stay put throughout even the most demanding skirmishes.
The sight also uses the MOJ™ footprint, making it compatible with mounts built around the popular RMR mounting standard. This gives you plenty of flexibility when mounting it to pistols, offset mounts or other compatible platforms without the need for proprietary adapters.
Combining premium materials, proven durability and a compact, lightweight design, the Vector Optics Frenzy-X FLEX 1x19x28 GenII Red Dot Sight is a superb upgrade for almost any Airsoft build. Whether you're putting together a race-ready Hi-Capa, a compact CQB SMG or a full-length rifle, it delivers fast target acquisition, dependable performance and the premium quality Vector Optics is known for.
