What is the difference between the long and short piston system?
I believe the AK uses a long stroke system! And i've read and heard about how reliable the AK is as in durability. So, why wouldn't some of these company (POF) that make gas piston AR's use the long stroke system instead of short stroke system?

Someone may correct me, but I believe that the POF uses a long stroke system.

POF-USA uses a short stroke gas piston system.

The AK uses a long stroke gas system. Its piston is part of the carrier and that whole mass moves back to unlock the action. The Dragunov for example is a short stroke. One of the benefits to a short stroke gas piston system like POF uses is a "softer" recoil because the piston rod strikes or taps the carrier and there is less mass moving rearward. Most if not all long stroke gas piston weapons have the bolt & bolt carrier tied into the piston rod which makes that mass moving rearward feel like it recoils more.

There are many debates about what constitutes a short stroke vs a long stroke and which one is better. Everyone knows that the AK47 is a proven weapon system but I do not believe that is the case because it uses a long stroke gas piston system. There are many newer firearm designs and most, if not all use a short stroke gas piston system. To this day, the weapon systems tested by our military that have had the least amount of failures all had short stroke gas piston systems similar in design to the short stroke system found in each and every POF-USA rifle. The top performer is non-existent in the civilian market because it was never produced.

So what would an SKS be? Or a Saiga 12, it has a tappet and a piston.

From what I have been able to gather, the SKS is considered a short stroke and the Saiga 12 is a long stroke. Don't takei it to the bank though.
