The 9mm AM (SR3) small-size assault rifle is designed to destroy manpower, wearing individual means of protection, and soft vehicles at a range of up to 200 m. The assault rifle fires a special 9x39mm SP-5 or SP-6 cartridges. The SP-6 cartridge, fired from the AM, preserves its 100% killing power upon penetrating two 1.4 mm thick titanium plates and 30 kevlar layers of body armor at a range of 100 m. Special reduced-ricochet rounds make the weapon efficient for employment in confined space.

The weapon is fed by 10- or 20-round magazines standardized with those of the 9mm VSS special sniper rifle and the 9mm AS special assault rifle.

The collapsible metal butt folds up to the receiver cover.
