Hey all. I bought this gun a while back and i'm in the process of SBR'ing the C39 pistol. It has a milled AK receiver which is nice, but all of the other receivers milled or stamped all have a flat back on the receiver making it easy to mount an adapter. Mine is slanted...




My question is has anyone ran into the issue and if so how do you get around it? If I mount any of the stock adapters onto this receiver, it will be angled downwards? Any idea's/ comments would be greatly appreciated. Thanks.
