A great rifle sling works when you hardly know it’s there. It takes the load off carrying a rifle for mile after mile, keeping your arm and shoulder muscles fresh for when it’s time to take a shot. But it also does a lot more, like help you lock your arm into position for a solid shooting stance, and smooth out your movements as you shift from a carrying to a shooting position with minimal chance of snagging on other gear. When looking for a rifle sling, think about how much you walk with your rifle, and whether or not you’ll use the sling to help support the rifle in standing and kneeling positions. And then think about these three other factors when choosing a rifle sling.
