AK Drop In Auto Sear V1
By s3igu2
---------Description---------
This is a drop in auto sear that will convert most AKs to full auto using 2 parts, the Sear and Trip Bar and a FIME FCG.
It doesn't require a Full auto bcg or cut rails in the receiver, this has the downside of not working
with some models with weird rails / BCGs that aren't made to the correct spec.
-------Materials Required-------
The FIME Trigger below isn't optional it will not work correctly with any trigger, buy the correct trigger or
you will end up wasting your time trying to make other triggers work. I cant reasonably support every AK trigger on the market
so i'm limiting it to the FIME.
