Granted, the saiga is an interesting option, but they don't sell them at the local Walmart or academy. I would buy one if I didn't already have a rifle in .223. I've been fond of the mini since I was in high school, which was many moons ago. Now that I have a post 2009 model, even better.
The saigas can be got in a 20" barrel, that's a plus also. Or, 308. Or 12ga, or .............
