AK rifles pair stamped or milled receivers with the platform's legendary reliability. The Zastava ZPAP M70 brings Serbian heavy-duty construction with a 1.5mm receiver and bulged trunnion, Century Arms builds the American-made VSKA and imports the Romanian WASR-10, and Arsenal's SAM7 line features milled receivers for collectors and hard use alike. Most run 7.62x39, with 5.56 options like the Zastava M90 and 308 M77 rounding out the family.
