If you are new to the AK and the concept of fast reloads and malfunction drills then welcome to basic training. Below is an excellent tutorial produced by a highly motivated tactical civilian. He covers common tactical reloads and malfunction drills from various angles so you get a 360 degree view of the techniques. StrikeHard Gear forgives the young man on his choice of AK chest rig and will look past that as the information conveyed is very good.
One common arguement you will encounter on the training field is whether to let your magazine drop to the ground or retain it. It's a "Ford or Chevy" arguement and a discussion for another day. The take away here is to develop a basic weapon handling technique and work it into your muscle memory via repetition.
That said, grab your AK and get busy.
