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

    Secure - Worry free

    The is the most secure mounting system for a free floating handguard available ANYWHERE. Yes, they are a PIA to install, but if you follow the directions even that goes smoothly. I would not buy anything else.

    KMR Alpha Rail

    This is now my sixth build using the KMR Alpha Rail. Just the best fitting, best looking hand guard available.

    Best rail system I've used

    Most lightweight rail I've ever seen, very modular and low profile, kind of an evolution to install but not too bad for a solid lockup to the barrel nut and upper receiver. Highly recommend this rail with the grey rail panels, looks awesome!

    The Best

    My second 7" to go with a 13". The 7s are on a 450 Bushmaster and a 300 Ham'r. The 13 is on a Grendel. BCM is a prime example of price, in the absence of value, is not a consideration.

    BCM Strikes Again!

    Fit perfectly on an Aero Precision Slick Sided Upper - as expected!

    Simply the best fore-end available

    Light, handy, vents heat. Gets rid of that huge boat anchor Colt puts on the M4 and makes a usable weapon system.
