Squad Automatic Weapon version of the 70/90 system. It can fit ALL STANAG AMMO CLIPS (including BETA-C MAGS), and all kind of optic devices, on the un-removable carrying handle. Furthermore, it features a "skeleton-stock" and an heavy barrel with a folding bipod. Got a S-E-F trigger group. VERY FEW of those are existing, as I think no Italian military organization adopted it.
