This REPLACEMENT Bridge is specifically for MREX MkII rails. The bridge will come with the necessary screws for mounting to the rail. A MkII replacement hardware pack will be required to complete the process of mounting your rail to your firearm.
***This is a replacement item! All MREX rails will have a bridge pre-installed and include needed installation hardware from the factory. This item is not needed for NEW Rails but intended as an ‘if needed’ replacement***
