I had one for several years about 40 years ago. Great rifles if hitting something aimed at is not an issue for you. At that time they were known for poor accuracy and it was a well deserved trait. Colt (the only prevalent maker at that time) AR's were the most accurate, Ruger Mini 14's next, and then the 180. HK's were available, too, but very pricey. 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
