I've done a bit of searching but found little info with regard to what size holes should be drilled for various pins in an AK build. It would be awesome if we could compile this info for new builders. For example, demilled Krinkov kits are not currently available and a lot of holes need to be drilled for the pins. What size holes should we drill for the:

RSB, FSB, Barrel Pin, and Trunnions?

Should they be drilled slightly undersized and then reamed out? Also, what about press fitting tollerances? What should they be for each hole?

Maybe someone who has done their own krink build from a new kit can chime in here.

Thanks,

The hammer & trigger pin holes are 5mm & 7mm. I also use a 5mm for the selector lever hole. Don't know about the rest

Thanks erik. Anyone else have some info to add? I was thinking about this last night. Would it be best to measure the pins with a digital caliper and then drill the holes based on this?
