Overview of the Centurion Arms Mid-Length C4 Picatinny Quad Rail

The Centurion Arms C4 rail system is a premium quality AR-15 handguard.  There are several features that help to set this rail apart from others on the market. The attention to detail and excellent manufacturing of this handguard make it a high quality piece that will last a long time.



The C4 Rail system gives you a wide expanse of Picatinny rail section.  The top section of the C4 rail gives you a continuous 12 o’clock rail section to provide an uninterrupted rail that is continuous with your upper receiver.  This top rail section is the perfect place to mount optics, night vision equipment, back-up iron sights, or other Picatinny accessories.


Easy to Install

The C4 rail system is a 2-piece design that was engineered to clamp onto a standard AR-15/M16 barrel nut.  This clamp on design has several benefits that make it desirable in a rail.   Since this is a 2-piece clamp on design, the C4 can be installed without having to remove the gas block, barrel nut, or other components.
