The Zastava M19 - the new service rifle of Serbia (adopted 2022)
Top: M19 with 6.5x39mm Grendel barrel and 25-round magazine.
Middle: M19 with 7.62x39mm barrel and 30-round magazine (note this barrel lacks a muzzle device)
Bottom: M20 compact carbine, here in 6.5mm Grendel. I am unclear if the M20 is a different weapon, or just a designation given to the M19 when issued with the short barrels.
Today at the range, I decided it would be 7.62x39 day, the ammo that many AK47’s use. That said, if you look at the picture you will realize not one of these guns chambered in 7.62x39 is an AK47! From left to right, my CZ Bren M2 with a Wolverine silencer, my Palmetto State Armory KS47, my VZ58, and my Sig Sauer 556r wearing my AAC 762SD. The most accurate was the Sig 556r.
