This is a brand new AR-15 magnetic magazine release tool for the Mag-Lock or Bullet Button. The Mag-Tool Low Profile is made from a high quality hard Polyoxymethylene plastic (POM). It has a strong 4mm rare earth magnet that attaches on the Mag-Lock or a standard Bullet Button. The MTLP has a nice square top textured surface which gives it a more appealing tactical look. This tool has a low profile and is ultra light. Now you have an easier alternative way to release your fixed 10 round AR magazine.
