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)
•Will cut through zombies, doorjams, debris, firewood, etc...
•It's a FREAKIN' CHAIN SAW on an AR15. OMG!!!
