The SECO carbon-fiber Thumb-Release™ tripod uses the same design as the popular 5217-04 bipod, but weighs only three pounds! The bipod features a large 5-lobe soft-touch rubber clamping knob, and legs of super strong, lightweight carbon fiber. Legs extend to six feet (1.8 meter) for use on uneven terrain. Collapses to 43 inches (109 cm).
