While the default rubber feet are the ideal bipod foot configuration for the widest variety of applications, some settings, shooting styles and setups can benefit from a properly built spike foot for extra purchase in loose soils and soft ground. One of the primary challenges in spike foot design is matching angles from legs of the bipod to contact surfaces. Gunwerks opted to design an injection molded, glass filled nylon, design that kept it lightweight, durable and manufacturable. The integrated angle of the spike feet matches the average splay angle on the legs for optimal contact and surface area with the stainless steel spike and toothed skirt to the ground. The resulting design is unlike any bipod foot you've shot with before, but so is the performance. Gunwerks Elevate Bipod Spike Feet Set AY-G2025
