The Exoskeletal Broadheads?are stronger, straighter and superior a patent-pending design built by archers and hunters, like you. The curved blades cut faster and penetrate longer. A combination of blades lying flat and a friction grommet under the blades eliminates external bands, and produces a quiet flight and field-tip accuracy. The pre-loaded blade angle is quick to deploy, and the head design features built-in stops for both closed and open positions, preventing arrow damage. The Meg 85 features an 85 grain head with an aluminum collar.
