Another gun I'd like to see would be a pump action .308 that took similar - but clearly different - magazines from my M14s. For instance if the latch tab were too low to be reached by the mag release on the M14, ensuring that they absolutely could not lock in place and would fall out under their own weight if you tried to stick them in by friction alone.
Or a pump.223 that took similar, yet different and non-transferable, magazines to the AR would be nice.
There would be no reason for these guns to look anything like anything else Norinco makes, or share any parts such as receivers, bolts, or barrels, IMO.
