he ZPAP M90 is made with the same techniques that you know and love from Zastava classic M70. The receiver is the Bulged 1.5mm trunnion receiver that gives the increased durability and performance after a long shooting session. This trunnion holds the nice 18.25″ barrel that has a chrome lining that protects the bore from the elements and improved longevity. For the part of the western twist this rifle is chambered in 5.56 NATO which opens up the possibilities for shooting at longer ranges. This rifle also comes with the an optics rail that accepts Yugo style optics mounts. And for that classic look and feel this rifle comes with nice walnut furniture.
