Ages 5 and Up, Eh?

I GOTTA get one of THESE for my grandson! (He's three now.)

And a close-up view of the kit, which appears to be based on the Swiss SIG 550:

Underbarrel grenade launcher & everything!

Of course, this would get the gun-control people's panties in a bunch, so I was unable to find a single on-line retailer who actually carries it.

Why am I not surprised?
