They were essentially two “Steelbilt” M37s joined side by side. Economy model making the most use possible of stamped parts.

That said I used a 12ga for a few seasons and it was reliable and fit me well. I had no trouble killing birds with it. The minuses were the trigger guard would slap the piss out of my knuckle every shot and the tiny extractors were a weak point. If I let it get dirty the 1/8” wide extractors didn’t have enough purchase to pull the empties out.
