What did brownells do incorrectly to the forgings?
^^^^ @Nzfly you still have the comparison photos? I cant seem to find the thread you put them in.
It was IIRC a beveled edge,
Trigger area milled to normal AR contour,
A machined "U" on the front of the magwell between the take down pin collars.
Just going from memory, was there something about the buffer retainer roll pin placement?
