NO, you idiot,, the minimum length for a shotgun barrel is 18 inches, not 16!!!!
I can't for the life of me understand why so many Freepers are so slavishly devoted to carrying ASJ's water when those morons know less about firearms than my hedgehog.
And it's not just a typo because dear old Paul Pawela -- should I call him PP? It seems apropos for some perverse reason -- makes the same mistake repeatedly through the article.
IIRC, the law once did say 18” shotgun & rifle but was later changed to 16” rifle after millions of M-1 carbines with 16” barrels wound up in private hands following WWII.
That came up again when GCA ‘68 was passed. I could be wrong.
