Question about these AKs:
DISCLAIMER: I don't intend to do anything illegal, I simply want to know.
All these weapons are semi-auto only, correct? Is it the trigger that makes it work in semi-auto or full-auto, or are there more modifications to the design to make it semi-only?
The semi-auto rifles have a different shaped disconnector and are missing two parts that are required to make it full auto. Here are the parts of an AK... remember that the two circled parts are required to fire reliably in full auto, and the disconnector (aka the "semi-auto fire sear")is shaped differently.
Now, you could make the semi auto ak fire in a fully automatic mode by simply removing the disconnector, which would let the hammer continually fall forward... but there's a big problem with that option. The rate of fire would be too high, meaning that the hammer would either follow the bolt home, resulting in no shot firing, or it would fire out of battery, blowing the rifle up in your hands. See, on the full auto rifle, there is a part (circled in blue) that slows the hammer from falling for a fraction of a second, allowing the bolt to make it all the way forward. SO, if you simply remove the disconnector, you might be able to get a few rounds out per trigger pull at an extremely high ROF (having to pull the charging handle every few rounds) before the rifle explodes in your hands. Good luck with that
