GatCrank 15 AR-15 Trigger Actuator

The AR-15 world has a vast selection of aftermarket parts from various companies, some of them are useful and actually improve your AR’s performance and some just make your credit card debt increase. There’s a segment of the aftermarket that certainly makes your wallet lighter, it’s the gadgets that make your AR-15 rifle shoot faster. Remember the Slide Fire stocks and Tac-Con trigger? They help you blast through a ton of ammo in no time.

Well move over Slide Fire and Tac-Con, now there’s the GatCrank 15 AR-15 trigger actuator! What the hell is the GatCrank 15? It’s an attachment for your AR-15 that fires 3 shots per turn that was created by a Redditor. It works with all standard AR-15 lower receivers and with standard mil-spec shaped triggers. It may work with some aftermarket triggers and AR-10 lowers as well. It’s legal in most states, sorry CA, CT, IA, MN. It actually fires pretty slow, kind of like a 19th Century Gatling gun. Check out the videos of it in action below. You can definitely fire your AR-15 much faster with your standard trigger but I’m guessing the GatCrank 15 wasn’t invented just to throw lead downrange quickly but as a fun range toy. It retails for $30 over at

    I thought all trigger “accessories” were required to not block access to the real trigger. That’s why the original gat-trigger was so awkward.

  • Mcameron

    eh, im willing to bet i can fire faster and more accurately without that do hickey on the trigger…… looks a little clunky and award to use

  • Anton Gray Basson

    Woah, people have had this on paintball guns for years. I think it was called the Firestorm

    • raz-0

      People have had this stuff for actual firearms for year. Gatling like cranks that mount in the trigger guard were on sale in the back of guns and ammo and such since at least the 80s.

  • TVOrZ6dw

    Pass- If I want to throw money away at a faster rate, I’ll do it at the strip club.

  • Joshua

    No…..just no.

  • thedonn007

    I would not use it even if I got it for free.

  • Jose

    That is a waste of time; resources and money. I prefer the bumpfire stocks and the quick, two-shots, selectors, to any of this crap. One day, even the ATFE will allow the use of three short burst for semi-auto weapons, and this type of junk will become history.

    • iksnilol

      Considering how crappy burst triggers are, you’ll prefer anything else.

    • JK

      What makes you think the BATFE is moving towards allowing three shot burst? I guess there’s the double barrel 2011, which is effectively two shot burst, but I’d be less surprised if they declared those machineguns rather than allow a triple barrel version. Unless, of course, the lawsuits come through. Then we might see full auto, I’d still avoid three round burst.

      • Nate H

        Even that isn’t truly a two shot burst. To be ATF compliant, it has two triggers. You could fire off only one barrel, theoretically, but I don’t think it’d function.

        • JK

          IIRC, part of the fire control system was unitized between the two barrels, in order to avoid timing issues. I think the hammer or sear.

  • cs

    The gat crank is the perfect companion to my Franklin Armory Binary Trigger.

  • cs

    Add a clutch, belt, and a doggie treadmill and I am a buyer.

    • phuzz

      A doggie treadmill wouldn’t be very portable, what you want is a hamster in a wheel.

      • cs

        If a jumpy lap happy puppy with a machine gun can’t put a smile on your face, then I don’t know what will.

        • cs

          Run for your lives!

  • Andrew

    This is so dumb. For real.

  • Vhyrus

    That is an atrociously low rate of fire. I can do better with a decent trigger and my finger.

    • Nashvone

      With the added bonus of having more mobility and accuracy.

      • Jwedel1231

        And an extra $30 in your wallet. Or $30 worth of ammo on your range bag.

  • Phil Hsueh

    And this is illegal in some states because why? If someone was intent to go on a shooting spree with one of these things attached to their weapon then by all means let them, it’s not like they’d be firing very fast or accurately with them on.

    • Alex Agius

      >implying gun laws are based on any common sense

  • iksnilol

    Hmm… what if used with binary trigger? Wouldn’t that be kinda 6 shots with one turn of the crank?

  • Looks like an accidental discharge waiting to happen.

  • Alex Agius

    kinda cool on a belt fed that should be auto, but on an ar15 its just silly, the slide fires are far better and safer than this (and with a bipod and sling mount can be fired 1 handed and get hugely cool results, see youtube for proof)

  • Xtorin O’hern

    a modified version of this, plus binary trigger, plus 9mm belt fed upper equals selectable ROF belt fed

  • Bill

    And the letters to the ATF start in 3, 2, 1….

    And they stole my porno name – GatCrank. It’s how I worked my way through college.

  • SlippedThroughTheCracks


  • Lee Attiny

    But it looks so practical. Lol

  • RickH

    Yawwwwn………a similar product was available starting in the late ’70’s, and you could put in on any rifle.

  • Cymond

    It looks like a slower, less versatile version of the GAT or BMF triggers. At least the BMF is only $20 and can mount on several different firearms.

  • It’s not me in the video, it’s the product inventor.

  • skusmc

    Waste of money etc.etc. but holy guacamole that’s a beautiful range.

  • AD

    It looks to me like this could be fairly easily modified with a gear system to spin faster (i.e. fire more shots) for each turn of the handle.

  • Daniel M. Ramos

    Wait a minute, if we are going to take a step back and start using cranks on our guns again, then I want a water jacket kit for my AR, damn it, so I can lug around 50 lbs of sloshing boiling liquid. Oh, and a tripod please. Then we could finally have five men crews for ARs the way they want us to use them in California right? HA!

    • Sid Collins

      Nevah ben dun b’for….

  • Lou

    This is new to you young guys. We had the BMF Activator since the late 1970s which this is a copy of except that the BMF worked and could shoot fast. This company has done a disservice to itself with this half ass video. Like all small gun companies, they think that marketing can be done DIY with social media and photoshop – hire a marketing professional who is a gun guy.

    • Kefefs

      I don’t think hiring a marketing guy would help sell a product that does literally nothing except slow down your rate of fire and make the gun awkward to use.

      • Lou

        The device should work as well as the BMF Activator since it appears to be a copy- it seems that the user is afraid to crank it fast. Of course if it does not work, marketing won’t help.

  • michael escamilla


  • Tierlieb

    Seriously? People dis this thing ebcause it is impractical? It is just a funny gimmick. And I bet it is only that a lot of non-shooters will want to try. For fun, you know. Which is probably a good advertisement for the dreaded fun part of shooting.

    I think there are a lot of things to criticize, like
    a) this should be a schema for a 3D printer. This is what they are meant for.
    b) if I were to sell this, I’d want to show my engineering skills: Some transmission, a quicker installation and some kind of fly-wheel mechanism to even out the ROF.
    c) the fumbly mag reload would lead me to think that I am not paying another enthusiast

  • J S

    small electric motor fitted to the shaft, battery pack inside a tactical flashlight case wired to the motor. That would get the fire rate up.
    Still not for me though.

    • Anon. E Maus

      Which is illegal though, this isn’t.

  • dltaylor51

    Attach a cordless drill motor and it would really sing but all it is going to do is waste ammo.

  • JoshCalle

    They were selling this back in the early 90s except it fired 4 shots per full turn. Same guys who made that POS hellfire trigger if I recall, they had those “gun bunnies” shooting machine guns in bikinis. Hell, I’m only 20, am I the only one that remembers those?

  • Great_Baldung

    That sounds like something that could have started as a joke over at reddit, and then someone had the bright idea to make it reality.

    • Anon. E Maus

      Crank triggers you attach to a semi-auto have existed for decades.

  • Sid Collins

    I have a God-given accessory that works better, is faster, fits all my guns, and can also be used to type this comment.
