Overview of the CMR 14 Modular Rail

The Centurion Arms CMR 14” modular rail system is a light weight and rugged handguard designed for the AR-15 modern sporting rifle.  This rail is packed full of features that make it very desirable and the perfect fit for your AR-15


Primary Features

One of the main features of the CMR is that it has an easy installation process.  The CMR rail uses a proprietary barrel nut.  The handguard clamps onto this proprietary nut to give you a solid mounting platform.



The CMR was made to give you multiple options.  At the top, 12 o’clock section of the CMR, you will find a full length Picatinny rail section.  This rail section will allow you to mount a sighting system or night vision equipment, as well as any other Picatinny compatible accessory.  The CMR has done away with the integrated full length Picatinny rail sections at the 3, 6, and 9 o’clock positions.  In doing so the CMR saves a lot of weight and also offer you a slimmer and more comfortable grip profile. 


Sling Integration

The CMR has integrated sling mounts.  There are four QD sling swivel locations on the rail, thereby giving you a great degree of flexibility when deciding how to run your QD compatible sling.  These QD sling swivel sockets are anti-rotational.  This prevent your sling from turning and getting tangled.



Please note that due to the extremely low profile of the Centurion Arms CMR Rail, Centurion arms can only guarantee that a Centurion Arms low profile gas block will fit under the rail.
