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
M70AB – Underfolder version of M70B
M70B1 – Stamped receiver (1.5mm), bulged trunnion, fixed stock
M70AB1 – Stamped receiver (0.9mm), flat trunnion, underfolder
M70AB2 – Stamped receiver (1.5mm), bulged trunnion, underfolder

At Forgotten Weapons I think the most interesting guns out there are the most obscure ones. I try to search out experimental and prototype weapons and show you how they work, in addition to more conventional guns that you may not have heard of before. You’re much more likely to find a video on the Cei Rigotti or Webley-Fosbery here than an AR or Glock. So, do you want to learn about something new today? Then stick around!
