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 associated with other neoprene slings. It works like a shock absorber and flows with your body movement. All models feature Non-Slip Grippers to ensure that it stays on your shoulder.
