Nerf Vulcan hacked into chaingun

We all know that modding a Nerf gun to fire up to 500 rounds per minute is not easy at all without a proper guide. Fortunately some folks always have enough time to make proper how tos for the ones in need. You don’t need much if you want a Nerf gun that has the equivalent RPM as an M60. Some extra voltage will do the trick, you can add a round counter for enhanced beauty and function. I guess you need to know how many rounds you’ve put into your targets face.
