Your phrase, "...your wooden-stocked 10-22..." led me to think you thought my mini-14 was a 10-22.
Too much thinking on my part.
Mini-14's are legal in MA:
Are there examples or categories of weapons that are not copies or duplicates of Assault Weapons?
Yes. Many rifles, shotguns, and pistols are not copies or duplicates of enumerated Assault Weapons.
For example, the following are not copies or duplicates under G.L. c. 140, § 121:
Any handgun on the August 2016 version of the state’s Approved Firearms Roster, available here.
Handguns are still subject to MA 940 CMR 16.00 et seq Consumer Protection Regulations;
Any .17 or .22 caliber rimfire rifle;
Any Ruger Mini 14 or substantially similar model weapon;
The MA Attorney General recently clarified the legality of the Ruger
Mini-14 because they screwed up when it was declared "legal".
It's still subject to some confusion but her clarification
says that a ".22 cal rimfire" is legal but .223 cal (NATO) is not.
I don't think the Mini-14 is available as a .22 cal rimfire but
am not sure.
Yeah, they call it the 10-22 ;-)
It is not really the same gun tho except in the most superficial
outward appearance. (An M1 Carbine sort of look)
My Ruger .44 is very similar looking too, actually just a slightly
bigger version of the 10-22. They are both straight blow back
operation. The Mini-14 is a rotating bolt thing.
