These two GG&G optical mounting rails were designed to mount easily over the integral rails of the AR15/M16 flat top receiver and work in conjunction with any of our back up iron sights. As they raise the line of sight by 1/2 inch, they offer a proper cheek weld when optical devices are attached. In addition, they serve to protect the flat top receiver's integral rails from the damaging wear associated with lever type quick-release mounts, especially those without buffer pads.

The Scout length rail extends two inches beyond the hand guards and clears the M4 forearm. It was developed to accommodate long-eye-relief "scout"-type scopes and also Aimpoint red dot sights with night vision monoculars mounted to their rear.

The Standard length rail has been employed mainly as a riser for conventional optical sights.

Both are manufactured from billet 6061 T6 aluminum alloy, black Type III hard-coat anodized per Mil-Spec, and meet MIL-STD-1913. These rails lock onto the flat top receiver by means of a full locking side bar and two round head socket head screws. This provides both a positive and perfectly aligned lock-up even on well-worn receiver rails. The socket head wrench required for installation is included.

Standard and Scout length mounting rails are manufactured in the USA at our Tucson Arizona factory. Because these AR-15 and M-15 rail mounting systems are used in combat situations, they are designed and tested extensively before they are sold, so GG&G can not only guarantee all of its rail mounting kits, but proudly stand behind them.
