Can anyone ID this bolt?

[Slowmo]

Can anyone help me identify this bolt? Found it in a box of parts I bought at some point and don’t recall what it goes to.

Very strange. Looks like it's actually just a bolt head, there's no cocking handle so there's likely a matching bolt body/bolt carrier that goes with. Does the bolt face fit 9 Para or something larger like 8x57? The separate FP makes me think it may not be from an SMG but something bigger

Found it, Aero survival rifle. The twin extractor slots for right or left ejection is kinda unique.

Great find slimshady and thanks for your help as well Strangeranger. I had looked for pictures of all the common SMG surplus bolts and so forth, but I never would have guessed that.

I initially thought it looked like a few different 80s pistol caliber carbines that used interchangeable bolt heads in front of a heavy rear section to change calibers, but the swappable ejection is a very uncommon trait. Once I started looking for that the Aero rifle came up.
