AEL Sistemas, a Brazilian subsidiary of Israel's Elbit Systems, will deliver 974 Guará tactical red dot reflex sights to the Brazilian Army. According to the Janes website, the devices were purchased in December 2020 by the Logistics Command for Imbel IA2 5.56x45 mm assault rifles, and delivery is scheduled for July and August. The tender for supply of the sights was issued in late 2019.
The Guará, a polymer reflex-style sight with night vision capability, was designed for aiming rifles and shotguns with both eyes open. The sight weighs 350g with a battery. A rectangular heads-up display provides 25x30mm rectangular viewing and a dot reticle with LED technology, and has optical magnification of 1x and 3–10 MoA (minute of angle) adjusting. The sight comes with on/off and brightness adjustment switches and a locking quick-release lever or fixed mount, designed to fit onto a Picatinny rail. The side-mounted power source compartment for one AA-type 1.5V battery provides approximately 3,000 hours of continuous operation. The Guará, which is water-resistant up to 10m and Parallax-free, is compatible with magnifiers. Development of the sight was started in 2016 by the Federal University of Rio Grande do Sul, the Brazilian Company of Research and Industrial Innovation, and the SENAI Institute of Innovation in Polymer Engineering, the report said.
