With the use of a stainless steel plunger, the cleat foot attaches easily and cleanly into the bottom of your bipod, quickly replacing the standard rubber foot. These feet are sturdy and reliable, and have phenomenal grip. Perfect for digging into softer, earthier materials, these feet are suited for dirt, gravel, sand, ice, and even logs! The spikes on the bottom of this foot are arranged in a circular pattern to best distribute weight. This unit weighs 2.1 ounces.
