Centurion Arms may be known for excellent barrels and top quality uppers, but they may soon be known for their new entry into the AR-15 rail market – the C4 Rail. These rails have some features that really set them apart from anything else on the market right now.
The C4 Rail has a two piece design that allows the user to install the rail on a standard AR barrel nut by simply removing the handguard retainer and delta ring assembly. The handguard retainer and delta ring assembly can be removed without removing the barrel from the upper which allows users with permanently attached muzzle devices to install the C4 Rail. That is a huge plus considering how popular 14.5″ barrels with permanently attached muzzle devices have become.
The C4 Rail is also relatively light weight, especially for a rail that uses the standard barrel nut. It comes in a wide variety of lengths for various gas systems and even “cut out” models that extend beyond the front sight base on the sides but still allow access to the bayonet lug. It snugs right up to the upper receiver in order to provide an uninterrupted or “monolithic” top rail. The C4 Rail also features several sling attachment points built in to the side rails and anti-rotation tabs that prevent the rail from spinning on the barrel nut.
All of these features add up to a very well thought out rail option for the AR-15. Check out the C4 Rails on Centurion Arm’s website.
