LS321-RD is a Picatinny-mounted infrared and class IIIA laser sight with a red/infrared beam and IR illuminator. The product is machined of 7075-T6 aluminum alloy anodized in matte black coating and fitted with a gel pad switch and Picatinny rail mount. Dimensions of 91x56x40mm and a weight of 244g make it a perfect choice for submachinegun, carbine, and rifle applications. Thanks to the sealed housing and an IP67 rating, LE321 is weather, dust, fog-resistant, and shock-proof. The utilized laser is a class IIIA with a wavelength of 635nm and a power output of 1mW and 5mW. Additional co-axially mounted infrared laser works in a low 0.1mW and high 0.7mW power output. Integrated IR illuminator output is the same as the IR laser at a high-power setting. A single CR123A battery supplies power to the sight. Windage and elevation turrets are adjustable in a 60 MOA range. LE221 Elite is equipped with an enlarged lever for comfortable operation in gloves. A solid mounting clamp for Weaver and Picatinny rails guarantees stable zero holding and pinpoint accuracy.
