BCM® KMR Alpha 13

 

All the advantages and features of Bravo Company's KeyMod™ Rail, now available in 100% aluminum

 

Manufactured from aluminum, it is lightweight yet durable. Also featuring a proprietary patent pending mounting, indexing and lock up system that mitigates 12:00 rail movement under heat generated from the barrel nut.

 

Handguard alone weighs 7.8oz!

 

1.3 Inner Diameter

1.5 OUTSIDE flat to flat.

Handguard flares forward (towards muzzle end) at the 3 and 9 O'clock positions approximately 1/4"

Actual length when measured to flare is 13.4"


The KMR barrel nut will fit over all mil-spec diameter barrels (max of 1")

Mounting hardware, 2.4oz, for a total of 10.2oz on a very long 13 rail.

 

The KMR Alpha is hardcoat anodized for corrosion resistance as well as to maintain a non-reflective finish.

 

The KeyMod interface system was developed by Eric Kincel (now the Director of BCM's product development team) to work in parallel with the current picatinny system. In many applications it will advance modularity past the current 1913 rail system.

 

The BCM KMR Alpha also allows for a larger range of modularity offering 4 different offset mounting positions between traditional 3,6,9, and 12:00 positions.

 

In the most basic of applications the KeyMod system allows for universal modularity between various manufacturers of accessories, and accessory rails. A big win for the trigger puller. As the industry advances the modular accessories will mount directly to the KeyMod instead of picatinny, allowing for a lighter, cleaner, and less bulky weapon system.

*Includes BCM KeyMod Sling Mount

Please note: Nylon/Polymer Picatinny rail sections are for NON-load bearing accessories only. For load bearing accessories, we recommend aluminum Picatinny rail sections. Do NOT exceed 20 in/lbs. when securing KeyMod Fasteners on Polymer accessories. Aluminum Picatinny rail sections may be torqued to 30 in/lbs

    The answer to the best AR-15 build..

    As someone who always deals in trial and error, let me tell you first hand that this is the rail you want if your goal is a sturdy, lightweight, and modular rail. This patent style mount is way better than the other manufactures out there that use the jam nut style. BCM's rail stays straight and put. With this being my first purchase from BCM, I can confidently say that I love this rail and look forward to adding more BCM products to the future build.

    Great product

    Easily the best rail I have used. It is much lighter than my previous rail and much slimmer. Also feels much more sturdy than any I have had previously, no noticeable movement in my iron sights when co-witnessed with my red dot sight. In all I am highly satisfied with my purchase
