Butler Creek's unique rifle and shotgun slings are designed with the hunter's success and comfort in mind. They combine the soft and durable features of water-proof closed cell neoprene with Comfort Stretch backing. This system ensures that you are buying the most functional and field proven weight-reduction system available.The patented design reduces felt weight and controls the bounce typically assoicated with other neoprene slings. It works like a shock absorber and flows with yur body movement.It actually reduces felt weight by 50% and makes your firearm 100% more comfortable.Conventional gun slings do not "give". Each step in the forest or field can pound a hunter's neck and shoulder muscles with a force much greater than the weight of the rifle. This results in pain, fatigue and possibly a missed shot at that critical moment. All models feature Non-Slip Grippers to ensure that it stays on your shoulder.
