FRENZY 1x20x28 TEK™ Red Dot Sight by Vector Optics

Looking for a reliable red dot sight that handles heavy recoil while offering fast and precise aiming? Want a compact yet powerful optic for pistols, PCC carbines, shotguns, or rifles? Then the Vector Optics FRENZY 1x20x28 TEK™ is an excellent choice. Its 3 MOA red dot covers only a minimal portion of the target, allowing precise shots even beyond 50 metres. The sight offers 8 daylight brightness settings and 2 night-vision (NVG) compatible modes, making it suitable for low-light use. The parallax-free design keeps the point of aim consistent with the point of impact regardless of viewing angle. Its compact 6061-T6 aluminium body withstands impacts, drops, and sustained shooting. At just 56 g, it adds almost no weight, yet handles recoil up to .338 Lapua Magnum. The sight is fully IPX6 waterproof and operates reliably from -20 °C to +55 °C. Thanks to its universal TEK™ footprint, it is compatible with various mounting plates. Included is a RIS rail mount. Power is supplied by a standard CR2032 battery with up to 50,000 hours of runtime (battery not included).
