This is another brilliant idea from NC Star that allows the use of the many tactical sights that require a mounting rail with your Mini 14 or 30. The rail fastens directly to the ring mounts on the Ruger receiver without altering the rifle in any way allowing the use of your Aimpoint or Eotech to facilitate close quarters combat with this excellent rifle system. Add a couple of 20 round magazines and you've got a very capable battle rifle. I offer a 100% money back guarantee.
