Here is a lightweight bipod with mount to fit any 7/8" tactical rail with Metal Feet such as those found on BT-4 and Tippmann X7s. Mounts easily with a simple thumbscrew. Bipod legs fold down when the secure switch is pushed and extend an additional 3 inches for comfort. Metal skid-style feet similar to those used on real machine guns for a secure stance in dirt and grass. Can be mounted so legs sweep forwards or back. Perfect for lining up that lone sniper sot or when laying down a barrage at range!
