Board Thread:General Nerf discussion/@comment-5895032-20130621160722/@comment-10582531-20130629185753

I recently realized that the barrel post in Nerf blasters is there for liability reasons; it prevents objects like pencils, sharpies, etc. from being fired from the blaster. Stefans might be OK for a prototype, but Nerf would have to create a hollow 'nano-dart' for the concept to reach production... and the barrel size I suggested is probably too tight to work with a clip system.

For comparison, 3/8" (.375") is just slightly larger than 9mm (.354") or 38 caliber (.357").

All this math is making my head hurt.

I hope this helps.
