The Bug-A-Salt Black Fly 3.0 is specifically tailored to the needs of the more serious fly hunter. The Black Fly 3.0 features custom improvements such as cross-bolt safety, trigger redesign and patridge sight for extremely accurate shooting. Simply release the safety and a pop-up sight indicates it's ready to fire. The Bug-A-Salt pest gun uses ordinary table salt to kill flies and similar bugs. Each shot uses just one pinch of ordinary table salt to drop a bug whole, leaving no nasty mess to clean up.
