M-LOK is a modular locking accessory mounting system that is a direct attachment method for hard mounting accessories to a negative space mounting point. Designed by Magpul Industries as an evolution of the MOE slot system used since 2007, the M-LOK system is being released as a free licensed platform to allow greater compatibility of accessories between all manufactures.

  • pithy

    That is the stupidest company name in the gun business. Should’ve just gone with L33T 0P3R4T0RZ

    • no

      I constantly get ads for them on Facebook. It seems like they’re a clothes company that’s decided to make guns and gun parts now. The vast majority of their posts are just pictures with the same chicks and 27 hashtags like “omgtubesocktuesday” or “riseabovetherestalwaysthebest”. So annoying…

      • You can get these same rails all day long on chinese commerce sites for $45-60 + shipping. They’re making jack diddly and using pretty much the same barrel nut as Noveske’s chinese made rails. (Yes, they’re on aliexpress too.)

  • JumpIf NotZero

    This is clearly a knock-off Noveske NSR with mlok instead of Keymod.

    Look… I know original ideas are hard and all, but just because you have a smoking hot chick and that’s awesome and all… But that doesn’t make you a real company. Please invest a few dollars into something other than marketing.

    The rifles strategically placed around SHOT, all the Facebook nonsense, is anyone falling for it?

    Idk… Good for them if they can convince anyone to fall for this type of nonsense.

    • mikomonday

      um, yea Era3 is Sheri Johnson’s (John Noveske’s wife) own project so of course many of the products will be based off existing Noveske designs.

      • JumpIf NotZero

        Uh huh… And the cloths, the catalog shoots, the Facebook posts of a tiny chick (met her, she’s like 5’3″), bla bla bla… It’s ALL marketing and copy-clones. There isn’t a single substantial thing they’ll ever do. I just can’t even sort of support a “company” like that when there are really hard working, innovative, and not breast-based based companies out there that are doing it right way.

        Also… FWIW… I replaced on of my NSRs with a BCM MKM and it’s a very superior product. The NSR just isn’t super light, it’s a weird overal length (went from a NSR 11″ to a MKM 10″, only lost .5″ of actual rail), it’s expensive, the barrel nut can be a huge pain on some guns. It’s just not a great design, I’ll sell my remaining NSR off my SPR/recce if I ever get around to it.

        Sheri Johnson took over Noveske after John died. I believe John was married to Lorene Noveske not Sheri Johnson.

    That’s where my pee comes out!


  • Budogunner

    Honest question: Why black Cera coat over black hard anodizing? Adds to production cost but provides what added value?

    • pithy

      Honest answer: BCUZ TACTICAL BRUH

      Pretty looks now drive the gun industry. Guido exterior over actual innovation.

  • Pranqster

    oh hell no, my rifle cost under $600 to build, no way Im dropping $300 bucks on a handguard, free float or not! The Alpha rail is like half that price.

  • Thomas Gomez

    When Shari Johnson worked for Noveske she was absolute pleasure to deal with. Good luck with your new venture!
