The CBC Industries free float 15″ Keymod rail is a modern designed forend made from high-quality aluminium, featuring milled picatinny inserts at 3:00, 6:00 & 9:00 position to increase the functionality and attachment points.
This AR-15 rail is built to handle the hardest use and abuse of tactical and competitive shooting while offering more versatility than other handguards. This forend was created for a shooter who demands versatility when accessorizing his/her AR-15.
Functionality is not the only feature a serious marksman looks for when purchasing a handguard, durability is equally as important. The CBC Keymod is CNC milled from aluminium alloy and hard coated anodized for added strength to ensure it will endure life-time of abuse.
The Rail comes with a proprietary barrel nut where the Handguard is clamp mounted with 2 screws for additional strength. The anti-turn millings prevent turning even at the hardest use. The barrel nut is 30mm and we do not include a Barrel Extension Torque Wrench.

    We’ve built 4 rifles with this rail system and every single customer has raved on how good it looks, the small diameter and smooth underside. Having the keymod on the bottom leaves smooth surface to shift your supporting arm position without having to ride down the rail you find on a quad rail hand guard. Also, the fit and finish are fantastic.

    I have purchased two of these. Great product at a great price!

    I bought this as an upgrade. It didn’t fit (my fault), but it’s such good quality I just ended up building a whole new upper so I could keep it.

    Excellent! Everything about this hand guard is excellent! Fit, finish and function. Definitely a hand guard I will suggest to my friends who are looking for a quality hand guard for a reasonable price.

    Thank you

    I bought this 15″ rail to replace the original plastic hand guard on my 20″ barrel AR15. I like the short rail sections on the sides at the front of the Keymod. The barrel nut and mounting screws provide a solid base for the 15″ rail.

    This is a great upgrade to keep my first AR15 relevant. It is the best quality rail I have seen in this price range anywhere.

    ALSO, Chris and the folks at CBC are great to work with. I met them at a gun show and discovered they are located very close to where I work in North Charleston, SC.

    I loved this rail on an upper that I had bought, so I bought another one. I replaced the rail on one of my rifles with this, and I will be ordering another one for a future build. If you like a slim rail that is quality built, you cannot go wrong with the rail.

    You simply can’t go wrong. Installed on a 16.5″ AR15 5.56. Price: UNbeatable. Rigidity: For years(The recess fit barrel nut keeps the guard concrete) Looks: 9/10(Rough along milled edges. Easy file fix.) Weight: 10/10(18oz. Carries easy.)

    Delivery: I’m not the most patient consumer. 2 days delivered with 3 day priority. That makes me VERY happy.

    All considered, I’m coming back to CBC very soon.
