Griffin Armament Introduces Modular Lightweight “M2” BUIS

Griffin Armament has been making quite a splash moving through the market outside their well-regarded suppressors. Previously, they released AR furniture and in October, released their HEDP (High Endurance, Dual Purpose) series of barrels. Now, they’ve set their sights on… sights! Griffin Armament has announced their latest offering, the Micro Modular Sights(TM), referred to as the M2 sights.

The new sights focus on modularity, with the ability to mount the sights either on the horizontal plane or on a 45 degree offset, either right or left! To do this, the sights are offered as stand-alone units that mount to a rail via a single dovetailed rail adapter held in place by a hex-key screw. The screw mounts through the sight and modular base to put pressure directly on the rail.

Outside the welcome inclusion of modular mounting, the sights themselves are quite the ticket. They are extremely low profile and light weight, clocking in at just 2.5 ounces mounted for the pair (horizontal mounting). Further, they are not manufactured from polymer, instead using stronger 17-4 stainless steel, which is then QPQ treated for corrosion resistance, strength, and to a black coloration.

The front sight is compatible with standard AR-15 front sight posts, adjusted via the common detent system. The rear is a fixed size aperture, adjustable for windage. Both front and rear will require a tool for adjustment.

The sights are available now as stand-alone items ($72 for either), a full kit ($184.95 – with both offset and horizontal mounts), and as an offset pair ($144). Individual mounting plates can also be purchased directly from Griffin Armament.

    Not a bad price compared to the KAC Micros, or the original KAC sights, which these look modeled off of. Is the front sight post the same as a standard AR front sight?

    • Uniform223

      I always like the KAC stuff but they’re just so gawd awful expensive.

  • Frank Grimes

    Damn good price.

    In what world is $144 dollars “affordable” for something you can get from magpul or troy for less than a hundred. Iron sights are way overpriced from every company, these things shouldn’t be more than like 50 bucks.

    • Flounder

      compare them to the magpul pros man… They are roughly inline with their competitors.

      Although I do agree that markup is huge. And it stings everytime i have to get irons.

      • CharlesH

        I guess I just find it ridiculous that they’re so overpriced considering they all do the same thing and are made of like 50 cents worth of metal and plastic. Ah well….

        Although, considering how overpriced almost everything in this industry is, I guess I should be used to it by now.

          Machining time is very expensive. So is tooling. I think average per hour machining time these days is something like $80-90 an hour. A lot more goes into production than just material cost.

            Still doesn’t explain why MBUS polymer sights still cost, what, over $70 for a set? I mean, they’re injection molded, right?

          • I think it’s because it’s what the market will bear.
            They’re clearly popular.
            If people will pay for it, why not?

          • Wow!

            That is the thing though, I don’t think the market will pay for it. I mean, I use el cheapo $5 chinese PTS MBUS sights for all my ironsights. Work just as well as the real deal and any other “high end” sights. Iron sights are simple stuff, it isn’t a scope.

          • BrandonAKsALot

            Plastics are an entirely different world. Depending on the molding method and types of plastics involved, cost varies so drastically.

          • CharlesH

            I’m not arguing against the other costs, but when you produce a commonplace, proven design; R&D costs are minimal and volume; even at those costs, should be large enough to keep the price down lower than the industry standard. I would understand if these or other iron sights were a “revolutionary” design, but these clearly are not.

  • Jeff Smith

    My must companies choose acronyms for their products that already exist? HEDP already has a meaning in the firearms/weapons world – choose something else.

  • Gary Kirk

    Interesting, have gotten rid of all my “short” rifles.. But like the similarities between these and the KAC, plus an offset option..

  • Jake

    is there a reliable set of iron sights for rails that doesnt take 2 benjamins to make happen?
