I'm not eager to pollute the existing AUG thread with a wild proof of concept fantasy, but I'm kind of thinking that an AUG would be nicely improved in its HD / Urban role if it were a .300BLK. Seems like the magazines and bolt are fine as-is, but it would obviously require an altered barrel. Just to get started, who do we use to bore out a rifle barrel to a larger caliber?
Any thoughts on the project?
