Any rifle, rimfire or other that is a semi auto is no longer available for sale, or transfer to those under 21.

They are now semi automatic assault rifles.

21 or over and you have to have training, a background check that includes the state perusing health records annually (even if you sell the gun) and there are storage requirements that if one has a gun stolen and it wasn't locked just so, or reported promptly, and that gun is used by a prohibited person, the owner can be charged with a gross misdemeanor or felony.

The irony is that if you buy an ar or ak pattern firearm as a receiver,, since they could be made into a rifle, pistol, pump or bolt action, they are exempt from the new laws.

So it will catch the plinkers and old battle rifles in the new costly rules, but not the modern sporting rifles/patrol rifles/assault weapons (what ever they are called by the pro or anti gun factions).
