AK Fail to Fire, Fail to Safety. Cause and Fix. C39V2.

This video is not to bash this firearm, just to show how this fail happened and how to quickly fix it should the same thing happen to you.
On the first shot of my wife's C39V2 the trigger did not reset, she tried to place the gun on Safe, and the lever would not move.
The safety lever on this rifle has a small nub that comes very close to the trigger return spring. When the gun was taken off safe the nub caught the spring and dragged it off the end of the bar it rests on, and snapped back under the bar.
This caused the trigger not to reset and held the bar up slightly not allowing the safety to be reset.
Once I figured out what happened this was an easy fix, I also bent the spring back a bit so that this would not happen again.
Other than this single issue, this rifle has run flawlessly.
