I recently went through a learning curve sourcing an extractor for a factory SMG. The extractor that I got was too long for the bolt. Visual differences include a seam running the length of the extractor, plus the standard screwdriver slot on the base is oriented 90 degrees off.
The extractor stuck out far enough that it hit the edge of the barrel when I hand-cycled the bolt. Had I tried to shoot with it, it would've chewed up my barrel. I took a few pics.
I've since seen some older posts in the forum about "too long" extractors, but given the shrinking supply (and my recent experience), I thought that it may be timely to share for anyone else looking to buy what may be available "out there". Be aware. I hope that this helps!
