The best way to attach an Aimpoint Comp M XD or Comp M2 to the M16/AR15 flat top is by means of the GG&G standard Aimpoint ring, which was designed to maximize the Aimpoint’s tactical features. Manufactured from 6061 T6 billet aluminum and black hard-coat anodized, this ring is attached to the base by using a squeeze rail design incorporating a single elliptical thumbnut. There is also a square locking cross bar for recoil control. The ring body has a built-in insulated spare battery compartment with a spare Aimpoint battery cap. This is an important feature and it's located on the side of the ring for easy access. Our ring is extra wide so that only one is required. To clear the M16/AR15 front sight, the low-profile standard GG&G Comp M ring must be mounted on our Scout length FIRE system rail.
