Gwot king - a must-have - LaRue Tactical Harris BRM-S Bipod and LT706 QD Swivel Mount

This might be the only bipod you will actually need if you have several firearms that you use. It's got the bigger knob to adjust the tension without having to buy the lever that sticks out. It's not as easy to use as the lever, but I can see why this is good - as it is smaller profile and still nearly as useable. The QD system takes a minute to learn and understand, but it literally works in the matter of about 2 seconds. If you have a KAC/GGG style foregrip on your rail, you can quickly unscrew the VFG, remove it, slap this on and deploy the feet in about 10 seconds, which is awesome if your needs change. I use the Sun and Shadow strap that connects the feet, so all you need to lower the legs is to pull just one of the legs. I consider this to be the most useful lightest, ultimate system that can be used on a variety of rifles, and the ONLY tactical bipod that has nearly as much use in theatre. Just spend the money on this.
