AGI Armorer’s Course for AKS-MAK 90-AK47 Semi-Auto Rifles

Bob Dunlap teaches this course on Mikhail Kalashnikovs masterpiece, the AK-47 Assault Rifle. This is the most successful, prolific and best personal infantry weapon in the world today. A cut-away gun is used so that you can actually see the operation and relationship of the internal parts.
If you want the quick course on how to get the Worlds Most Popular Assault Rifle apart, back together, and operating as intended, then this course is for you (if you want the “long course,” look into our basic 108 hour Professional Gunsmith Course.)

If you noticed how often the terms “explanation” and “visual demonstration” are used, you may be getting some idea of why this course is necessary for any AK owner, or someone who intends to be.
