The Osprey spring loaded bipod gives you the tactical advantage of muzzle control while shooting. It can be used in a prone position for added stability or retract the legs and use it as a bipod foregrip. With our inch and a half rail, you may add shooting accessories that require picatinny/weaver rail. Comes in 3 different colors: Black, OD Green, or Tan. These bipods are backed by Osprey’s industry leading no-nonsense lifetime warranty.
