A Howa mini has magazines and stocks... Or you could use AR15-sized magazines if you can figure out the bottom metal.
I'd love an UL, custom-quality mini action with a Tikka or Rem700 trigger that I can run a Jefferson Outdoors box mag in an UL stock..
Mini mags are average at best
Ar mags coal is too short for anyone wanting a proper custom 223.
The jeffersons bottom metal is not reliable in at least 2 of my cases.
