yeah, but first he needs a name lol.
Or a gun part you know, like the barrel of a gun. I found some cool (and funny) names that'd fit for gun part inspired names for people (And dogs) lol, like Clip, Flintlock, Hammer, Lock, or Mag (For magazine)
Though if we're gonna go for the box type, maybe Casey or Cas (for a case or cask) or Drumm (for drum) or Chester (for chest storage)
