The OMG-AR15 Unicorn zombie gun

Marque Cornblatt made the OMG-AR15 Unicorn zombie gun using Smith & Wesson parts and an 18v pole saw. "It's very accurate," he says. Below, a video of it in use.

Inspired by the recent trend towards rifle-mounted chainsaws, we at Guns & Gardens wanted to give the idea a try -- our way.

First, we decided to keep the budget low, so we used the OMG AR15 as the base rifle. Second, we wanted to design an attachment that was easy to make with limited tools. And third, we wanted the ability to remove the chain saw and use it without the rifle. And lastly, it has to appeal to little girls.

We decided against modifying the saw too much, so instead of cutting it up and re-distributing the battery and power switch all over the rifle, we simply flipped the saw over and reversed the direction of the motor and chain - so the saw is upside-down, but it operates as if it was positioned normally. We also removed the saw's safety switch because it was creating a critical delay in response time.

This is the result:

A CA-legal Smith & Wesson M&P15, chambered in .223/5.56
Tri-color dot scope, 6-position stock
18v Rechargeable chain saw with fast-swap bayonet mount


•Ni-Cad battery (not Li-On) •It gets splattered with gore
•Everyone wants to borrow it


•Costs less then $100 (AR15 not included)
•Excellent ergonomics
•Will cut through zombies, doorjams, debris, firewood, etc...
•It's a FREAKIN' CHAIN SAW on an AR15. OMG!!!

    1.  Because it looks like a Cuts Of Meat diagram?

      Also, was that a Ted Raimi impersonator?

        1. No Jerwin, it doesn’t. It shows the user the likely effect of their shot placement. This diagram has nothing to do with “maiming” unless you think that people who practice defensive shooting try to *avoid* the areas shown in the diagram. 

  1. On the one hand, ha-ha, hoo boy, that’s ridiculous, biting satire, etc.

    On the other hand, it’s still a gun. I dunno, I guess I’m not used to seeing weaponry on display on BoingBoing? Yeah it’s comedic, yeah it’s tech. But let’s just say it hits a little too close to home, I guess? It’d be funny if it wasn’t true, but sadly it is.

    ..personally conflicted… carry on…

    1. do you have a problem with posts about vehicles?  how about staplers?  pencils?  they’re all tools, right?

      guess what.  so’s a firearm. ;)

        1. so you’ve never heard of competition shooting?  or hunting?  or recreational shooting?

          PS: you know cars kill more people in the US than firearms, right?

          here’s an idea of what i mean:, i recognize that’s dated information, but it will give you an idea just how much more dangerous cars are than firearms.  and it’s easier to buy and drive a car than it is to purchase a firearm.  that’s terrifying.  

          1.  It’s true. I’ve shot guns many times. Never killed anyone though.

            Plus: this is obviously intended for the undead, so it doesn’t count as a people killer from the git-go.

    2. I don’t think you can even call it “ironic” that “comedic” is such a filthy-looking word. Honestly, I can’t bring myself to use it. It says something about the user. Something way, way too much. 

      And, like Borges, I will say “crapulous” when it applies.

    1. I’ll just leave this here…

      EDIT: And this is actually pretty relevant in this moment, considering the 9th Circuit Court of Appeal’s decision on CA Prop 8!

    1. FWIW, if the saw is a Black & Decker, it’s designed for use at the end of a 10-foot pole, and only weighs 12 lbs including all ten feet of the pole.  So yeah, it’s gonna be totally front-heavy, but not as bad as it could have been.

      My one concern is that the chain won’t be properly oiled if the saw’s upside-down, but then I’ve never investigated the lubricative qualities of entrails.

  2. I love this.  Had to repost for a friend’s daughter.  I’ll take mine in standard matte black, please.

  3. Hello Kitty/Pink/little girl themed AR15s aren’t totally new, but a chainsaw attached to one certainly is.  Also, guns’n’gardens is generally pretty lame =  But this creation is pretty cool!

    The Smith and Wesson M&P 15 is a great gun.  And for those of you who are a little perturbed by the scary black rifle look, consider that it functions exactly the same as your grandfather’s semi-automatic hunting rifle. Cosmetics don’t change the function.

    EDIT: On second thought, this creation isn’t that cool… they just plastered the gun with stickers? Kinda lame.

    Also, here is another zombie/chainsaw gun/fantasy toy thing.

    It’s all so silly!

  4. I have seen other chainsaws mounted on ARs before – but this one wins, hand down. I like how the stock looks like Steven Tyler decorated it.

  5. I can see videos of people shooting rifles anywhere, I wanted to see that chainsaw in action cutting something up…. Where’s the gore?

  6. My mother-in-law gets this magazine for reasons unknown to even her.  Looks like there’s finally something worth looking at inside this month’s issue.

    Also, saw the pic before the name of the gun and actually said Oh Mah Gawd. Out loud.

  7. It may be “very accurate” but  he’s clearly a novice zombie killer. Rule number one is Headshots Baby, center mass is for noobs

    1. I’m shooting at a target, not a zombie. I suggest you watch the videos at before judging my zombie killer cred.

    1.  Because a young girl might enjoy shooting? I think it’s messed up that you apparently equate [likes a gun] with [being a violent person].

  8. I could be wrong, but I don’t think it’s CA legal with that grip.  Sorry.
