Overview of the Centurion C4 Cutout Mid-Length Rail System

This Centurion Arms AR-15 quad rail provides you with a well constructed and uniquely engineered system that enhances the capabilities of your carbine.  The main standout feature of the Centurion C4 Rail is the cutout section that allows you to retain the use and function of your standard A2 front sight block, but also gives you extended rail space.  This AR-15 rail system is a high quality piece that will serve you well.


Made to Be Rugged

Centurion Arms has a reputation of putting out quality AR-15 parts that can handle hard use.  This rail is no exception to their phenomenal track record.  This AR-15 quad rail starts out life as a solid chunk of billet aluminum.  The specific alloy of aluminum used for this handguard is 6061-T6 aluminum, a material widely used in the aviation industry and well known for it’s excellent strength and light weight. This gives the rail excellent rigidity and ensures a long service life.  In addition to using a high grade aluminum, Centurion Arms also provides you with grade 8 phosphate finished bolts to install the rail.  This makes for a very durable system that will not let you down.


Free Floating

The Centurion C4 quad rail was engineered to be a 2-piece, free floating design.  By allowing the barrel to be free float, you maximize the accuracy potential of your AR-15.  Since the handguard will not deflect or affect the barrel harmonics, there are less variables to account for, which can lead to greater accuracy down range.


Mounting System

The C4 Mid-Length Cutout rail uses a 2-piece clamp on design to attach to your standard barrel nut (not included).  This mounting system allows this quad rail to remain extremely light and have a very firm mount.  Also, the two-piece design makes for very easy installation.  Since the quad rail can be split into two parts, installation will not require removal of your front sight block or a permanently attached muzzle device.
