I'll take "OP you planned that" for .420. or did I...

Blaze it right?

I was machining a new muzzle brake for my airsoft gun when the center of the part where I was drilling holes for gas ports just happened to be .blazeit4. (Y must you be confused? I'm sorry for that pun, for those that don't understand look at the Y axis measurement)

This was the muzzle brake I made. Aesthetically useless
