Garbage! UTG bipods are manufactured to the lowest standards! These have no business being mounted on a weapon, perhaps an airsoft gun or BB gun. These bipods are manufactured in CHINA and their customer service is routed through CHINA as well! UTG bipods utilize cheap hardware and consequently torque under minimal stress. The bipod I received twists about the yaw axis when simply folding and unfolding the bipod's spring assisted legs. I called the customer service number provided on the packaging and my call was routed to CHINA!!! The customer service representative "CSR" spoke broken English and was unable to resolve my issue, at the end of my call this "CSR" directed me to their website...Don't purchase this bipod!!! You will be disappointed!
