I've been playing with mods in Bethesda games for more than a decade and this mod itself is one of the highest quality gun mods I've ever seen in a game. Although the mod does come with some weird immersion breaking locations, it can easily be fixed with this mod
Summary
The SA58 FAL mod allows up to 9 different variations of the FAL from coldwar to modern-Anomaly Tarkov era FALs.
