Matrix Arms is the (real) firearms manufacturing subsidiary of Matrix Aerospace, a high precision CNC machining contractor for various firearm companies and defense agencies. Based in Claremont, New Hampshire, Matrix Arms manufactures all of their weapon parts and accessories at state of the art facilities right here in the USA.

Keymod is the name given to a universal interface system for firearm accessory components in an effort to establish a system superior to the MIL-STD-1913 accessory rails currently in use. This system consists of two parts, the KeyMod slot, and the KeyMod nut. This system is intended to be used as a direct attachment method for gun accessories such as flash light mounts, laser modules, sights, scope mounts, vertical grips, rail panels, hand stops, barricade supports, and many others.

The 5.56 Charlie KeyMod Handguard is a lightweight free floating handguard featuring a continuous Mil-Spec 1913 Picatinny rail. Constructed out of 6061 T6 Aluminum and hard coat anodized for superior finish and strength. The sleek extrusion with KeyMod attachments creates a light weight design that can support lights, sights, lasers, and all other accessories only where desired. Three hardened Allen screws for rock-solid alignment and hold with upper receiver. All Victor models feature a QD insert hole for quick release sling capability. The Charlie is machined for aesthetics and functionality. The C design creates a platform that reveals the flash suppressor, but still giving functionality of both the extended grip and full Picatinny rail.

"Got this rail for my Avengers M4 .It fits tight on the supplied barrel nut. It has a very small gap of a 1/16 inch between the upper and the rail. The gap could be eliminated with some modification.
