The Mini-14 (for example) has a wooden stock, and looks like something out of Little House On The Prairie, in part because it was brought to market at a time where the M-16, a descendant of the Stoner AR-15 design, had acquired a reputation for dreadful unreliability. In an urban environment, it's just as problematic as an AR-15; what's your point?
Another almost perfectly unhelpful argument is the irrationality of assault weapons bans. This is the Nelson Muntz of firearms regulations argument. The original AWB proposals were sane and straightforward: they intended to regulate any semi-automatic long gun with a detachable magazine. It was the 2A crowd, and particularly the NRA, that fought off gun control advocates to the absurd position they occupy now. It's not some article of faith among gun control advocates that grips and barrel shrouds are actually important. The NRA is the reason we ended up here, and now they're telling us to stop hitting ourselves.
Also, another example of a firearm with a wood stock? The AK-47.
