This M16/AR15 carry handle mount is excellent quality and better than most others seen on the market. The mount is constructed from a single solid billet of aluminum which gives it the light weight properties, and unmatched strength. The scope mount will attach to any AR15 or M16 carry handle (fixed or removable) and can be installed in literally seconds in the field. The mount guide rails allow your optic to be removed and reinstalled with great repeatability. The see-through design allows you to take advantage of the iron sights even when your optic is installed.
