Ultra-light Harris Bipods are lightning quick and manufactured with quality heat treated steel and hard alloys. The bipods are quick-detachable and clamp to the QD stud of bolt action rifles with conventional stock design. Carrying your rifle with a sling or shooting off-hand is not impeded by the use of a Harris Bipod. Series S Bipods rotate to either side for instant leveling on uneven ground. Hinged bases have tension adjustment to eliminate tremor.
