Registering your firearm is not required in MO, that is part of America, not the PRK, MD, MA, or other anti-gun hellholes.
However, getting a folding stock may fall under the "questionable" part of legality, at least until September 14, 2004 when the "Assault Weapons" Ban of 1994 expires, which limits folding stocks, pistol grips, flash-suppressors, and bayonet lugs on semi-automatic firearms with removable magazines. Also, you may not purchase any box magazine made after September 13, 1994 that can hold more than 10rds of ammo. If its made before that, its ok, but not after that.
You should check into that. BTW, a good forum for these types of questions is
The High Road. Try the Rifle Forum there, and tell them I sent you. My handle here is the same as over there. Drop in the General Discussion and introduce yourself.
