While this might look like a nail gun, trust me: it isn't

While I'm sure that DeWalt makes a very high-quality nail gun that's perfect for any job that could be completed using a nail gun, this is not it. No, this is an M16 assault rifle that's decked out to look like a DeWalt nail gun. Of course!

I’d just picked up a new (to me) M-16 and was in the process of fixing it up a little. It needed new furniture anyway, so I sourced the safety yellow stock, guard, and grip. Then, I went down to the DeWalt factory service place a few miles from the house to get a sticker. There, I saw they had brand new battery casings, so I picked up one of those too. I got home, found a short magazine , and got to work.
Fortunately, I think it's safe to assume that no one will ever confuse this for a nail gun and blow a series of bullet holes in their new porch. But you never know.
