Uh, the ban didn't affect the Mini 14, just the capacity of the new magazines sold with it. 20 & 30 round after market magazines are fairly readily available.
You are correct. Still looking for the right rifle. Had one ID'd in Arkansas but it got away.
In so far as one may outfit a Mini-14 with a folding-stock, a pistol grip, a bayonet lug, a grenade launcher, or a flash-suppressor, then I believe that the law DID affect the Mini-14.
I believe that a Mini-14 built prior to the ban and having two or more of the "evil" features is a pre-ban gun and was not subject to restriction. Once the ban was passed, it became illegal to add two or more of such features to a Mini-14, unless the gun had been assembled with at least two of the evil features prior to the ban.
Do some research when buying after market mags for a mini 14 many are junk.
