Chainsaws for N-Strike Rails! FUN!

Perpetual Play has been awfully sneaky about recent ZombieStrike releases for Nerf.  We've seen a few of them reported by our friends across the pond.  Here's another one that was just spotted state-side for the "Zed Squad" simply called the "Chainsaw".  This isn't just another foam toy to smack Zombies with.  Take a closer look and you'll notice there's an N-Strike Tactical Rail attachment for under-slung chainsaw action.  There's a handle grip on the back just underneath the tac-rail attachment.

These were found on a local store shelf in the Midwest.  Pictures were taken by a fan on Tactical Tag's Facebook Page. 

I haven't seen one in person, so I'm curious as to how sturdy it really is and how it'll hold up... but it's neat to finally have an N-Strike Rail attachment out of all these swords and foam weapons!

EDIT (again):  Added even more photos below for those curious about this!  Including shots on blaster with a Retaliator, SideStrike, Magnus, and SlingFire!
