D.I. Optical ATPIAL & Mk.19 Mount | SHOT 2017

D.I Optical is a South Korean company that has dealt mainly in optics mounts to heavy machine guns such as the .50 BMG M2, and automatic grenade launchers such as the 40x46mm High Velocity Mk.19. Recently at SHOT the company unveiled their new DILAD02, a laser aiming module with very similar dimensions to a PEQ15, but at more than half the price with a suggested retail price of $550. The device comes with a picatinny mount and has visible and IR laser capabilities. Body is made from 6061-T6 aluminum and it is waterproof to three meters, weighing 8.8 ounces. It takes one CR123A lithium ion battery, inserted into the forward section, alongside the firing port. Controls are from the rear, while calibrations are made by two dials along the side that utilize a sort of Aimpoint cap type system with the two exposed dots. The system can be activated by a press button on top, or can have a pressure switch plugged in from the rear. Battery life is listed as up to 10 continuous hours on a 20 mW setting, while 35 continuous hours on the 5 mW setting.

Although a tried and true Military PEQ15 it isn’t, the DILAD02 should be coming to the U.S. market in April of this year, and with a $550 price tag I can’t see why it wouldn’t take the laser aiming modules by storm, provided the device stands up to reliability testing. Given that most of us aren’t sleeping in monsoons, conducting live fire attacks in the Mojave desert, or fast-roping out of CH-53s, I can’t imagine why the module wouldn’t serve as an excellent alternative in the civilian or LE markets to the rugged PEQ15 or PEQ16 series currently serving the Armed Forces.

The company also makes this neat Mk.19 picatinny mount that attaches to more recent versions of the Mk.19 with a mounting bracket on the right side of the launcher.

    What do people actually use these for on the commercial market? Playing around with your NVG’s, or are they just more durable for being on a rifle.

    • Porty1119

      I was wondering the same thing. I guess that if you can afford NVGs, you can afford to play with gadgets that cost as much as a low-end AR.

        Hog hunting, I have two civilian ATPIAL-C’s on a pair of shorty 300BLK’s , two mill spec PEQ-15’s on a SCAR 17 and AI, one DBAL D2 on a 458 SOCOM and DBAL-PL on a M&P Pro. And yes I have a pair of BNVD single gain NVG’s that make all this party.

        If you have never shot hogs, at night, under a pair of head mounted NVG’s then you are missing out on the single most fun you can possibly have with guns. Quite honestly, it completes me….

        • some other joe

          I would argue that at this point, you’ve stopped hunting and moved on to exterminating. Destructive, invasive species and all that, I’m not judging at all.

          • Phillip Cooper

            I think that is the entire point.
            That you get tasty, tasty bacon and ham in the deal is just, well.. bacon on top of the fun.

    • Wow!

      Well for some with large amounts of property or in fairly large and expensive neighborhoods but not quite rich enough to afford a private security company (but with a fashion sense that having lots of lights on at night is “tacky”), having a night vision setup with an IR flashlight is actually a reasonable self defense option if your security system pings a potential intruder. Not giving your position away gives you concealment which gives you standoff to call for help, because unfortunately in these times, there are a lot more criminals who aren’t really as interested in your stuff as they are “settling the score against the privileged”.

    Dildo2 laser from Dong optical…wonderful…

    “…the rugged PEQ15 or PEQ16 series currently serving the Armed Forces.”

    I don’t know if I’d exactly call the Insight/L3 PEQ15/16 models ‘rugged’…

  • swede1986

    The Mk19 is chambered for 40x53mm rounds, not 40×46.

    • Nicks87

      40×46 is low velocity, the Mk19 uses high velocity rounds. Im an Air Force guy and even I knew that.

      • iksnilol

        Well, you had plenty of time to look and read up on stuff while sitting in a cozy chair in an air conditioned room 😉

    For those interested in this device and have been impressed with the relatively high quality (price comparatively) of Holosun recently, they too are coming out with a DBAL/PEQ type unit any minute. I’m not sure of the price, but I suspect even less than this unit’s $500 price. I’m holding out hope it’s reliable rugged.

    • Flounder

      I’ve heard a rumor that they made lasers before they got into sights. And it kinda shows, because you can buy any of their optics with multiple laser options integrated.

      I don’t know about a PEQ clone but they already have IR and visible (red and green) lasers available on their website. Although i only remember them being built into their optics not stand alone units.

    • Alexander Nguyen

      I don’t know if they have some even newer models coming out but Holosun’s combo lasers go for about $550 and $900 with IR illuminator, so actually not cheaper at all. Considering DI Optical is capable of making sights to Mil-Std 810G, I would probably prefer whatever they make to Holosun, although things could be different with this product. In the end, a US made laser is not that much more ($700-800) and I myself will continue paying for fair labor. Considering that manufacturing in the US costs 4-5x as much, the margins on Asia-made goods are actually way higher so I know these companies are actually greedier than our “expensive” home-grown firms and think if they make a product that looks like the real deal, they can sell it for about $1-200 less and make way more. Sadly, they’re usually right. We mix up frugality with engaging in the global industrial slave labor complex quite often in today’s society I think. We want lower prices and 10-20 years later turn around and wonder where all of our jobs are. There are consequences to our actions as a collective and you may think you r purchases as an individual don’t affect much, but really, they do.
