This High Profile Rail Riser is designed for any 20mm RIS/RAS Accessory, and is designed to lift it up off the Rail. This is particularly useful for those trying to use a Lower Face Mask with a Red Dot Sight, as you might find that you Mask stops you from aiming down your standard Rail System.

The Theta Optics High-Profile Optics Mount is incredibly easy to install, needing only the two Allen Screws to be loosened to place it on the Rail. Tighten these up again to hold it in place. The Riser Mount offers a 3.1cm raise, which should be more than enough for someone who wants an easier time aiming down their Sights. Another key use of this Riser is so that you can still use a Sight whilst you have a PEQ Box installed in front of it.
