BCM® KMR Alpha 7

 

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 4.5oz!

 

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 7.39"

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

 

Mounting hardware, 2.4oz, for a total of 6.9oz on a 7" 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

    Just got in the game of building AR pistol and heard BCM were one of the best names out there when it came down to hand guards. I love the look and feel of my KMR Alpha 7" key mod float hand guard. It's like as a feather and that's what I'm looking for. Thank you!

    Carbine Length Handgaurd

    Posted by Brandon on Sep 22nd 2016

    For those of you who are wondering this is the length of KMR handguard that can be used with a standard A post front sight and carbine length gas tube. I just put it on a Ruger AR 556. I used it with the Ruger's front sight. Works perfect! I am amazed!

    Well made fits great!

    Posted by anonymous on Sep 22nd 2016

    Hardest part of installation was getting the old barrel nut off. I bought the 7" carbine version and it works perfectly with the fixed sight. I put the sling swivel at the end, I thought it might tweek the handguard but it's rock solid. In the future I'm going to replace my gasblock/sight and get the 14" version for so i can use an extended reach grip. Nice product, I like it!

    The KeyMod hand guard is easy to install. The instructions are easy to understand and comes with all the equipment you need except a torque wrench.
