I'd never thought of this before but maybe that's how they got their name. Fire a round it it will hit somewhere within 180 degrees of the muzzle
Never had a problem hitting anything I was aiming at with mine. This article seems to agree with my experience: http://www.thefirearmblog.com/blog/2015/02/18/historic-pre-ban-assault-rifles-the-ar-180/

I personally found my 180 to have very similar accuracy to my Colt SP1. The SP1 may have had a slight edge, but nothing that would ever matter in the field. Both of the 180's that I have owned were solid 2-2.25 MOA rifles.
