Been interested in potentially getting me a milled kit to eventually put together, since a milled AK home built sounds pretty appealing lately. I’m especially partial to the fixed stock Yugo kits if I can find them for a decent price, and looking through the two milled receiver sites I’m familiar with ( tortort and cnc warrior), though neither seems to have them currently in stock, both have the same, giant opening in the back of the receiver for the fixed stock yugo’s in the pics. I was expecting it more to resemble the stamped rear trunnion setup, since the stock seems to have the exact same profile. Among I was kind of wondering just how the stock works with the rear section of the receiver to get an idea on what exactly goes on there. Can someone show me pictures of the new receiver or original stubs with stocks and such installed so I get more of an idea of how the milled receiver differs? Thanks.
