The Centurion Arms C4 rail is a lightweight rail system which clamps onto standard AR-15 barrel nuts. This simultaneously strong, yet lightweight design can be installed easily onto standard AR-15 uppers after removing the delta ring and hand guard cap, a task easily accomplished with hand tools.
The Centurion C4 rail features built in QD sling swivel sockets with limited rotation on the left and right side of the rail. This is a free floating rail system, which enhances accuracy and allows installation of aiming lasers, optics, and backup sights. The C4's profile is slim and oval like other high end railed forearms on the market.
This is the Carbine Front Sight cut model designed for barrels with carbine gas systems and standard front sight bases. By extending the rail past the standard FSB on a rifle, it grants users more rail real estate, and allowing for better mounting of lights and aiming lasers.
