No tools needed to adjust: Bipod can be locked and unlocked with only your thumb and finger, while you are in position, within seconds. * Dirt and weather resistant: The integral dust shields in the Pod-Loc spacer protects the clutch area of the factory Harris mechanism. The clamp lever body is synthetic and the internal parts as well as the spacer are stainless steel. * Low profile: The locking lever can be pulled back slightly to disengage the internal ratchet without effecting the lock tension. Thus, the Pod-Loc clamp lever can be "parked" against the stock to minimize snags when you are on the move. All stainless steel surfaces have been blacked out for a low visual signature. * Standard issue on all U.S.Marine Corp M-40A3 Sniper and S.A.M. Rifles as well as the new FBI and BATF sniper rifles.. * No permanent alteration: Your bipod can be restored to issue configuration within 2 minutes.
