I've got a 7.62x39 build going on based from a 16 LWH but so far I've not found a complete factory bottom metal setup. What I've found is a top bolt release bottom metal and a "wider" top bolt style.
Since I'm building this with a Richards Microfit stock I can modify the sear to have a top bolt release but does anyone know if the trigger gaurd will stick out since the bottom metal tang on the top bolt release is thicker than the tang on the top bolt release version.
Or if you have a complete set up let me know
