The "Dog Soldier Series" Jack the Reaper LR1 open reed was designed with the help from world champion predator caller Steve Criner. Through his vast years of predator calling afield and in competitions, he always battled lip and mouth fatigue when calling for long periods of time. To combat this, Flextone added the patent pending "Lip Cushion" which achieves a firm grip on the mouth piece. Jack the Reaper Long Range comes with a specially designed mylar reed that will carry longer distances. The softer body not only makes for better gripping and reduces unwanted sounds when in contact with your gun.
