The SECO Quick Lever Bipod with Thumb Release Legs 5217-50-XXX and 5217-51-XXX ranges come with open thumb screw clamp heads.
SECO 5217-50/-51 bipods use SECO's Quick Lever locking mechanism, made of non-marring Delrin® for durability. The Quick Lever bipods have plenty of positive grip thanks to an 80-durometer EPDM (Ethylene Propylene Diene Monomer) rubber plug.
These features allow you to set up and detach your 5217-50 or -51 bipod to and from a pole in no time, so you can move to your next reading.
