The Bipod Leg Extensions were designed to cater to hunters that want to achieve a kneeling or sitting appropriate height with their bipods.
These extensions are 10" long and will fit all G1 LR-10 models, FC-10, all G2 bipods, PC bipods, WB Bipods, and HD-50 models.
Simply remove the rubber foot and support cone (if your model has one), screw the extension on the bipod, and add the desired Accu-Tac feet.
