Black Rain Ordnance M-LOK Rail System

Black Rain Ordnance Rail

Words are cheap.  Action defines character.  When Magpul put their money where their mouth was, pulled up shop and moved to Texas, they showed their character.  Likewise, when they developed the M-LOK mounting system and offered it as a free licensed platform for all manufacturers to use, they demonstrated a genuine interest in fostering compatibility across the entire industry.

Thanks to the open licensing, Black Rain Ordnance is able to provide slick rail systems like their new BRO-MLOK-10.  This 10 inch rail system is 100% compatible with accessories utilizing the M-LOK attachment system.  Recessed for optics, the rail provides 6 quick disconnect points and weighs in at just 12 ounces.

The company is also offering a 15″ version of this hand guard that weighs 16 ounces. Called the BRO-MLOK-15, it also has 6 QD points. The 10″ model carries a suggested retail price of $279 while the 15″ version is set at $289.

Not to wax nostalgic, but imagine a world where the big players did the right things just because they were the right things to do. Sure, Magpul is profit motivated, but many times doing the right thing for the customer is better for the bottom line anyway.

These rails were introduced at the National Association of Sporting Goods Wholesalers expo at the same time as the company’s new CQB stock.

Of course, Black Rain Ordnance is not the only one supporting the M-LOK standard. Troy jumped in with both feet, offering rails and accessories for both the AR and AK platforms.

    So, where are the MLOK slots?

    • Anon

      The whole article is a bit screwey

      • JumpIf NotZero

        Yea, I get why Magpul is awesome. Then there is a generic rail mentioned.

        Also, the number of M-Lok slots goes down as the rail gets shorter.

      Oh I’m sorry, what kind of groundbreaking innovation are you churning out? Oh that’s right, you’re just a weekend warrior with a keyboard. Sorry, mistook you for someone important.

    In any industry with standards, you either set them, or you end up following them.

    If you set the open standard, you get a major say in its extension and evolution. If you let someone else set the open standard, you are always playing catch-up (plus you have an installed-base burden with your proprietary stuff).

    And a “proprietary” industry standard is no standard at all (unless trivial to reverse engineer and circumvent, in which case it’s not terribly proprietary).

    Speaking as someone who worked in the computer industry, and had to deal with the consequences of some in management failing to grasp this.

    I feel like I’m missing something.

    I don’t see enough product to justify the price when compared to the alg defense rail I have.

    • Redfoot

      +1. My ALG rail is wicked light, came adorned with slots, and a tool to install it as well. The M-Lock products are really lightweight, but I have not tried out any Keymod products for comparison.

      I just ordered one, I have no idea why it isn’t on every gun out there. Light, lots of real estate, free floating, awesome shape,and so much cheaper than alternatives.

  • Bwill

    Didn’t magpul move to Wyoming?

    • BillC

      Their manufacturing did. Their HQ is in Austin, TX
      This is just a poorly researched, written, and photographed “article”. At least finally somebody used the right spelling of “ordnance” this time.

  • uisconfruzed

    It looks like a Seekins rail.

    There we go fixed sort of……..
