You win a prize...honestly I never gave a Winchester 1200 a second look. They had a 4 lug rotary bolt...ARs have a rotary bolt head....I'm sure the list goes on and on.

Maybe I should have said "Benelli perfected it"...why you think the Beretta A400 and the new Browning A5 along with several others using it...

Not because Winchester used a similar bolt in a junky 1200.
