Could be. But the lower lip on the bolt suggests that it might feed from a magazine. Also, the cut on the back may indicate a striker fired gun. Perhaps a modified bolt for a closed bolt or semi auto conversion or both. Judging by the very slight pitting it seems before 1960’s.
Looks like a blow back bolt for a pistol class cartridge. It fires from a closed bolt. It is striker fired or Reising type sliding hammer. The reduced diameter suggest a semi conversion for an open bolt SMG. I’ve checked my resources but can’t find a match.
My guesses are H&R trial M1 carbine, Cristobal carbine, or Finland Suomi semi conversion.
“Things have been a little easy”
That they have.
A bolt extension that replaces a shot shell, for a pistol cartridge conversion?

It sure makes me think of a Sten bolt
