Full Details & Specifications

Centurion Arms C4 Rail Handguards


The Centurion Arms C4 rail is a lightweight rail system which clamps onto standard AR-15 barrel nuts. This strong and lightweight 2-piece 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 patented C4 rail system is a lightweight, rugged, 2 piece free float rail that when installed gives the uppers a continuous 12o'clock rail. The C4 system is the lightest and most rigid rail that clamps to a standard barrel nut on all AR15, M4, and M16 type weapons systems. This design allows the installation of the rail on an upper assembly without removing the front sight post or permanently attached muzzle devices.

The C4 rail also 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.

Weapon outfitters had the best price I could find on the C4 rail, I purchased the 10 inch rail for an 11.5 build and it is everything I hoped it would be. The fit and finish are excellent and it’s just sexy af in my opinion. The crew at WO got it out the door in record time, as usual with all my orders from them. WO for the win and a customer for life!
