I called the company trying to find some black hornets and Mike Sohm,the owner, answered the phone. Helluva guy. Ended up talking him for a bit and was able to locate a retailer that still had some in stock. Screwed em on, no adjustments needed and off I go. A short time later I drove one through an elk. The Hornets are tough. 80lb bow slinging a 573 grain arrow, at 6 yards I shot dead through his sternum and the arrow stopped at his hip joint. Only damage to the head was a nick off one of the bleeder blades. I’m sold. Great company, great product.
