The M1 Garand and SKS are hardly obscure. Pretty darned popular IMHO.
Ruger Mini-14 is one of the most popular rifles out there, not to mention the 10/22, although that is only .22 cal rimfire.
I don’t think a Garand is covered by said law, because it doesn’t have any of the list of accompanying features (thumbhole stock, pistol grip, flash suppressor, etc).
A No. 5 Enfield (”Jungle Carbine”) is, however, covered, because it accepts a detachable magazine and has a flash suppressor.
Tyrants and morons abound.
