seriously, the flat is a pain in the ass. yes, it can be done and there are even bending jigs out there to assist in the bending.

by the time you buy the flat and a jig, you could have bought almost two ready to assemble receiver from itm/oow.

if you are going to build several ak's over the years, i'm still not convinced the flat is the way to go.

also, in only two weeks, global trades will have their new, made in the usa receiver on the market.
