bipod lead rifle

I modeled and printed this bipod for my Gamo plumb bob rifle, the rifle has two picatinny rails on each side, which is different from most center bipods. The two parts of the bipod are attached to the side picatinny rails with a quick release fastener, allowing the bipod to be removed quickly and easily if required. All parts have been printed in PLA, except for the screws, springs and the tube which is made of metal for more solidity when shooting. Cut the metal tube to the length
