The GG&G standard AR-15/M16 scope rail riser is a 5-inch mounting rail that clamps over the flat top receiver and lifts your optic half an inch (brand part no. GGG-1002). GG&G designed it to work with its MAD and A2 back up iron sights, and the standard length sits flush with the end of the receiver when one of those sights is mounted. The extra height gives a proper cheek weld behind a red dot or a conventional scope. It also takes the wear that quick-release mounts would otherwise put on the receiver rails. The standard rail is the shorter of two lengths GG&G makes, and it is the one built mainly as a riser.

Key Specifications

• The rail raises the line of sight by 1/2 inch, which gives a more natural cheek weld with red dots and conventional optics.
• It attaches directly to the AR-15/M16 flat top receiver, so no handguard or barrel work is involved.
• Overall length is 5 inches, ending flush with the receiver when used with a GG&G back up iron sight.
• The top dovetail is made to MIL-STD-1913, so standard Picatinny rings and mounts fit.
• It is made of 6061-T6 billet aluminum, a rigid alloy that GG&G designs and tests for combat use.
• The finish is Type III hard coat anodizing in non-reflective matte black per Mil-Spec.
• A full-length sidebar gives positive, aligned lock-up even on worn or out-of-spec receivers, and the rail weighs 3.9 ounces.

Frequently Asked Questions

Does this rail work with back up iron sights? Yes. GG&G designed it to work with its MAD and A2 rear back up iron sights, and it sits flush with the end of the receiver when mounted with one.

What is the difference between the standard and scout length? The standard rail is 5 inches long and is used mainly as a riser for conventional optics. GG&G also makes a 7-inch scout length rail that extends 2 inches over the handguards.

Does it protect the receiver rails? GG&G states that it protects the integral rails of the flat top receiver from the wear caused by lever-type quick-release mounts.

Optics that sit too low on an AR make for an awkward cheek weld, and a riser rail fixes that without replacing the upper. This one is machined in the USA and backed by the maker for life. Order it from our Lubbock, Texas gun shop with direct shipping, and see more scope bases in the same category.
