Explaining the Yugoslav / Zastava M70 Series of Rifles

Yugoslavia never received a technical data package or license for the AK; they reverse engineered the system themselves in the 1960s. In the process, they created a version of the AK noted for its ruggedness. In addition, they added a number of features to facilitate rifle grenade usage. Over the course of many iterations the rifle remained designated the M70, leading to a lot of confusion about what models are what. Today we are going through the whole series of changes.

M70 – Original milled receiver, with bolt hold-open, fixed stock, and screwed-in barrel
M70A – Underfolder version of the M70

M70B – Milled receiver, pinned-in barrel, standard magazines, fixed stock
