    Nice rail cover, makes it easy to quickly identify your weapon and caliber at a glance, which is nice when you have multiple ar-15s. Easy to install, good deal.

    The product looks exactly as shown. There's no hardware; it just kind of slides into place. I haven't fired by 300 Blackout to see if it will stay on, but it seems secure.
