FRENZY FM 17×21 MGT(TM) red dot sight by Vector Optics
Looking for a compact and durable open-style red dot sight that mounts directly to a RIS rail or pistol slide plates with the MGT(TM) footprint? Need a low optical axis, side-loading battery and a motion sensor for automatic ON/OFF? Then the FRENZY FA 17×21 MGT(TM) from Vector Optics is the perfect choice. It offers a 3 MOA aiming dot with 9 daylight brightness levels and 2 ultra-low NVG levels. The motion sensor helps conserve battery life, and brightness is easily adjusted using the side control buttons. The CR1632 battery can be replaced without removing the optic, so you don’t need to re-zero after each battery change. The FA (Fast Acquisition) series is made for rapid target transitions, fast shooting and everyday carry — ideal for tactical and sport pistol shooting with recoil resistance up to 1000G. It can also serve as a backup red dot sight on rifles chambered in .308 Win or lower. Thanks to the MIL-STD-1913 (21mm) RIS mount, installation is quick and simple. The FRENZY FM 17×21 MGT(TM) is compatible with pistols equipped with Optics-Ready slides using the MGT(TM) footprint. It is also equipped with an aspheric lens for a crystal-clear, distortion-free image.
