Harris Bipods S-Type Swivel (tilt) to Compensate for Uneven TerrainMade in America, Shipped from America, Competitively Priced... Don't be fooled by Foreign Copies!- The Harris S-Type Bipods tilt from side to side so that you can level your rifle as you aim. Side to side level is called "Cant". If you are "Canting" a rifle to one side or the other, you will throw off the accuracy of your aim. The Harris Series S Bipod design allows you to level your rifle from side to side as you're aiming. It does this under adjustable friction tension so it stays put once your crosshair is level. And just like the original Harris 1A2 bipods, all you need is a swivel stud in your forend to attach the S-Type Bipod. Once attached, you can adjust the friction tension with a friction knob. Make it move looser or stiffer to suit yourself. To Order, Choose from the Check Boxes Above...Features of Each Model
