Burris Optics, founded in 1971 by Don Burris, used to be one of America’s biggest optics manufacturers. In 2002, the company was sold to Berreta, the oldest company in the world. Since 2002, Burris’ products have been progressively gaining in popularity in Europe thanks to Berreta’s distribution network there. The company’s product line mostly includes red dot sights, along with hunting and tactical riflescopes.
The open reflex red dot sight FastFire 4 has been introduced in 2019, but Burris started to produce it in 2022. The dot features compact housing, weighing 46 g.
Fastfire 4 is made of aluminium alloy. The open compact reflex red dot sight is also waterproof, fog-proof, as well as shock-proof. The battery compartment is positioned behind the lens, which means the user does not need to remove the sight from the firearm in order to change the battery.
The elevation adjustment is located on the top of the Fastfire sight, and the windage adjustment is located on the right side of the sight. Both adjustments are made using a torx wrench.
The click value on Fastfire 4 is 1 MOA, meaning that one click moves the point of impact by 1.5 cm at 50m.
According to the manufacturer, the Fastfire 4 device has extended battery life in comparison to the FastFire III model – 26.000 hours. Also, when comparing it to the previous model, this one sports a bigger window, which results in faster target acquisition.
