The Allen Helix Bipod (Model 5201) is a lightweight and durable two-leg shooting support constructed from a combination of nylon polymer and aluminum. Designed to mount directly to the swivel stud of most sporting rifles, the Helix Bipod provides a stable prone shooting platform with a vertical adjustment range of 9.50 to 12 inches. The legs fold quickly and easily for transport and storage, and deploy rapidly to the shooting position. The rubber feet provide a secure, non-slip grip on a wide variety of shooting surfaces, making this bipod a reliable choice for hunters and target shooters alike.
