The Universal Bipod Mount(UBM) was designed to be a secure mounting solution for the majority of Harris or Picatinny style bipods.  The UBM features 8 Pic rail sections with a narrow center section allowing for an integrated Harris-style bipod mount. The UBM is the solution for real-world shooting environments that require shooter adaptation on the fly. Installation is simple: just use the existing holes in the bottom of the stock with the provided mounting screws.
