Bought what I thought was a HK91 wide forearm at a gun shop today for cheap. Wasn't quite sure since it wasn't labeled "HK" didn't have the usual bipod attachment point and indents, they had an old slimline forearm there and it looked more or less dimensionally correct. I'm on the road and can't try mounting it on my rifle but after looking at a few pictures online I'm not so sure what I got is the usual HK91 wide forearm. Besided the previously mentioned lack of bipod stuff it curved where it meets the receiver. It was cheap so I'm not too concerned if it doesn't fit but I'm curious just what I may have purchased.
First pic is a couple HKs w/ the normal wide forearm and the rest are my new purchase:
