[General Modern Fantasy] Why not make a gun that shoots magic ?
gpt
So, a gun that shoots magic doesn't require a projectile, so you don't need a barrel.  Solid metal rod would work.  Since it's magic, aiming is probably more about where you want it to go and not where you're pointing it, so a stock is unnecessary.  Again, being magic, you can probably fudge the sizes a bit too, something more handgun sized than rifle sized.

So a solid rod, maybe 12ish inches in size.

What does that sound like?

**TL:DR** It's spelled "wand"
