The ultra-light Harris Bipods are lightning quick and quality manufactured with heat treated steel and hard alloys. The bipods are quick-detachable and clamp to the QD stud of most rifles that have a conventional stock design. Carrying your rifle with a sling or shooting off-hand is not impeded by the use of a Harris Bipod. Hinged bases have tension adjustment to eliminate tremor or looseness in the crotch area of the bipod. The folding legs have completely adjustable spring-return extensions (Except for Model BRM and LM) and have an all-weather black anodized finish.
