The BR-7.62FAC is FACs latest assault rifle and chambered for their new 7.62 cartridge. This new assault rifle round is an improved version of the .320FAC rifle cartridge. Its predecessor was designed to promote reliable case feeding and extraction in bolt action, semi-automatic rifles and machine guns under extreme conditions, and because of this was chosen for rework. FAC reworked the bullet shape and weight balance to obtain wider range, enhanced penetration and higher accuracy than its predecessor. The main motivation to develop a new cartridge were ballistic problems with the .320FAC rifle cartridge caused by its weight and bullet shape. The .320FAC performed great in short range assault weapons and had good penetration and stopping power, but started tumbling on wider range. The tumbling was caused by the beefy shape of the bullet and so FAC decided to create a new round to grand highest standards for their products. Starting in February 2017, FAC engineers experimented with different parent cases and after intense testing decided for the .320FAC in April. 2017. The next step was to figure out how to optimize this new round for higher accuracy and stable trajectory. The outcome was a weight balanced and reshaped bullet that formed an aerodynamic optimized package with similar performance than the .308 Remington in a bit shorter form. As the bullet was chosen and the dimensions were fixed, FACs assault rifle division started to design a new rifle for this cartridge as well as new bolts and barrels for the existing .320FAC rifles, like the .320 Mk.XVIIIb or the ACR IV. Also bolt action rifles such as the Scout were adopted for the new cartridge.
