Whilst perusing retail ads for their weekly gun deals, I came across Gander Mountain's ad and they have listed a Bushmaster AR, a Carbon 15. They listed it on sale for $649, down from a regular price of $699. This means, of course, that one could purchase it from a sanely-priced retailer for probably $600.

WTF is this thing? Why is it so cheap? Has anyone heard of it? Does it have any issues?

I'm not a fan of .223, but at this price it might be crazy not to buy one.

...if it's any good.
