Sorry I can't post a picture but that is ther type f cut my foreend has. (Maybe mine is raked just a bit more)
My rifle is the same year also. I guess this means that is the style they cut in '91? My foreend isn't attached wxactlly square either it was drilled a little off where the cross pin goes thru. Poor QC I guess but I never re-drilled it and remounted it correctlly. The rifle works fine and unless you look hard you really don't notice it.
Man I sure love the power and accuracy of the 392! I have the Williams sight mounted on mine and the sight really aids accuracy at all ranges! I consider the reciever sight a MUST HAVE accessory!
