The M70 rifle made by Zastava firearms is one of the best and most widespread AKM variant in the world. Over 4000000 have been built. It was used in conflicts on the Balkans (in Yugoslav wars and Kosovo war) as well as the Gulf war, Afghanistan, Iraq, Libya, Syria, and it's still in use today.

Zastava M70 provides a nice alternative to the overused AK (AK47) and AKM.
The model comes in .max, .fbx and .obj formats, with 2048x2048 diffuse, specular, gloss and normal maps.
