I would say your average semi-automatic rifle consumer is going to want something that he or she has either used in the military, wants something to hunt hogs or varmits with, a modular rifle they can modify for whatever purpose they desire, or something like they saw on a video game. The
AR-180B doesn't radily lend itself to those missions, despite being what I consider a fine piece.
I think they're cool because that's what's they trained with on the pilot epsidoe of SWAT.
