Wishing I Had Machine Tools

I thought of a product I'd love to see on the market, which would probably cheese off a lot of high dollar tacticool accessories makers: the bayonet light. Make a high-power tactical flashlight that can be mounted on an AR-15 or Mossberg 590 using the standard bayonet mounts. Why waste a lot of money on expensive fore-end replacements when you can just use the bayonet lug, the original accessory rail? I wish I had some simple milling equipment so I could try to whip something up.
