Thanks for the encouragement.
To answer some questions. Yes, machining the receiver is mandatory to allow the mag to sit high enough so the bottom of the bolt will catch the round. The bolt has to be machined so it will slide in between the mag lips. The trigger groups fwd ears need to be trimmed back and the bolt hold open catch has to be reworked. Of ofcourse the stock mag hole has to be widened and extended and the mag release channel cut
The hard part was trial and error. The constant remove and trim and figuring the correct angle for the mag. It may look like it's sitting on a 90 to the receiver but it's not.
I was contemplating doing a few of these. My friend is already lined up. Cost wise I'm definitely not gonna get rich of this as the time invested would make the cost astronomical if shop hours are used.
In The end if a manufacturer wants to be involved something like the vz58 magwell adapter can be manufactured on scale. The receiver is also needed to be modified
I was thinking of buying a few refurbished no matching Sks's and selling them modified with the adapter.
PS to hobby machinists like me. Don't even bother with HSS end bits on the receiver and bolt. It mangles them
if you don't want to machine the bolt you just insert the magazine on a open bolt... cant do it when it's closed...
