This Bi-pod features Easily adjustable legs that swing 90 degrees and lock in up and down positions. You can swivel the bi-pod on the latitudinal and horizontal axis giving you more options in rough terrain. Metal reinforced polymer makes it very quiet to deploy compared to all metal construction so this bi-pod is preferred by other types for hunters. Adds about 7" of height when in lowest position and about 10" when fully deployed. Includes Direct Mlok Mounting Hardware so no additional rail sections are required to mount.
