Cloud Defensive COR – Multiple Options


Available Options:

Cloud Defensive COR

The Cloud Defensive COR lowers your switching to the heart of the rail. So no more being forced to work around your hand guard. Put your light/laser activation first by recessing the switching into the rail and optimizing your ergonomics in the process. By doing this your OWL or LCS unit no longer sits as high as it once did, which mean your field of view improves. Particularly when it comes to optics sitting in co-witness or lower 1/3rd co-witness mounts. The COR is compatible with any mil-spec upper and many non-mil-spec uppers. It is compatible with low profile gas blocks in both the carbine and pistol length configurations, but it is not compatible with piston driven operating systems.

Cloud Defensive COR Features


Optimized the length of the COR for the barrels it’s used with and includes a full BCM Barrel Nut assembly. The COR series with a 9.55” length rail that is perfect for 10.3 and 10.5” barrels. And of course it can be used with longer barrels as well.


COR was designed from the ground up to support the Optimized Weapon Light (OWL). They pair perfectly together with the COR being sized to within thousandths of an inch of the OWL mount. When paired together, OWL appears to be built into your rail.

Remote Switches

COR is compatible with both picatinny models of Cloud Defensive Light Control System (LCS) and other brand switches, such as the Surefire SR-07 and DS-07. You can place remote switches for the IR lasers in that recessed channel as well. Unfortunately, COR is not compatible with the Unity Tactical TAPS series.


COR is also designed to work with all the common IR designators on the market. Including the B.E. Meyers MAWL, the L3 PEQ-15 series (LA-5, ATPIAL, ATPIAL-C) and the Steiner DBAL-series. The lasers all mount in front of the recessed slot and the switching then sits down in the channel, whether housed in one of our LCS units or not.


Cloud Defensive’s hand guard has wall thickness of .100”, which is thicker than the others we have measured. In fact, they never found an M-LOK rail that is thicker. With the thicker rail, we get great heat sync and dispersement. And you get a rail that is incredibly strong and works precisely how it should.


The rail proven M-LOK technology to give you the ability to mount accessories as needed.


Cloud Defensive finished the rail by integrating forward and rear ward integrated QD sling mounts. Because having to buy extra mounts for your rail should be a thing of the past.
