Taking some parts in trade, coming with them is this cut down carrier.
What is it?

Need more pictures than that - the top will have the maker and year (example: FMP 6/69), is there a slot to the rear of the carrier (FA vs. SA)?
Not that as much is what us gun is the length cut for if any at all.

For those of us who speak english, what does that mean?
What is this carrier cut for length wise? To long for hk51, too short for g3 or g3k.
Looks like a HK33 bolt carrier.
