i called them and the guy who answered (not curt) said he....thought it was 5 mil


does anyone know if it is a 4.5mm pin or the 5.5

5.5 only soviet russian was 4.5 74m (100 series is 74m pattern actually) and bulgy use 5.5 his flat will work with his stock set

his stock set is out of stock I'm buying one with 5.5mm pin....so that will work?

The flat will work regardless,it's the type trunnion you have to try and match-The Bulgarian trunnion is 4.5,just checked mine.
The set you linked to me to ask the guy is 4.5
I know theres an adapter pin to make the 4.5 stocks fit the 5mm trunion,but I dont see any for the other way around.
You could drill the 4.5 trunnion out to make the 5mm fit,but it looks like it might be close,dont want to weaken it.

All the pins and latches you can get from K-Var as well..

I must be mistaken I thought Bulgaria always used the 5.5 like the modern Russian but bob is right the flat makes no difference it's the trunnion and stock that matter, they do make adaptor pins to use one with the other but their angles are a couple degrees different so while it works it looks and feels funky, just make sure you match up the right stock with the right trunnion. Gunsnorthwest.com makes trunnions and hardware
