Hi Duane, we do not recommend using metal nailers with Raptor. This is because the drive chamber must have a very tight fit to support the nails insertion. The Omer tools that we sell have been specifically designed for Raptor.
For CNC hold down Raptor 15 ga. finish nails would usually be recommended. They are able to penetrate many more species and thicknesses of wood, including MDF spoilboards. Hope this helps.
