I was just reading about the Mark 1 USMC 870 that had a beefy bayonet adaptor. It said prototypes were made before the Mark 1 design was utilized. Both with heatshield and without. Is this maybe one of those prototypes I wonder? Or maybe an Armory job, or just a bubba special?

Calling remington, they said it was made around 71-73. But that is about all the info they knew.

I measure the barrel it's 18'' and factory. It's not cutdown. It's marked cyl as well. But there are no date codes on it I can see.

This one has me confused.
