No registration needed! New Nail gun made by DeWalt can be used for home defense. It can also drive 16D nail through a 2x4 @ 200yrds. This makes construction a breeze, you can build a fence while sitting in your lawn chair. With a 100 rd mag, you can finish the fence with minimal reloading.

And yet another reason for me to hang out at Home Depot.
