Take a minute to appreciate the wonders of high frame rate image capture, aka slow motion video.
There is nothing quite like watching a machine that works its entire cycle of movements in fractions of a second dialed back so the details can be observed.
I wrote a post yesterday about how gas systems work like a hydraulic system and it uses timing to properly leverage each of the parts to do their jobs. Well the AK is one of the best systems to see that process work in real time. It had large parts that can be seen in operation safely with the top cover removed.
Kalashnikov Group has helpfully filmed this in action and in high resolution. Under the high frame rates and excellent image quality we can track each movement as it occurs. The hammer dropping to ignite the primer and powder, firing the round. The bullet passing the gas port and sealing the system to push the piston. The point where everything is in motion and we can see the order of operations take place at a pace we can track and process. You also pick up on all the extra, completely normal, motions and flexes and movements that occur when firing a firearm.
Oh yes, and it is election day so go do your thing.
