I do have the manuals. I mentioned in post #15 that it appears to be a rubber O ring from the magazine limiter plug. I can't say it is for sure though. I didn't take any of the guns apart except for removing the barrel of the Mossberg 12ga., which I reinstalled in the spot where I found the O ring on the floor later. I dismantled and reassembled the AR rifle too, but in a different room.

I went to my parts box. I had a magazine capacity plug for a pump shotgun to limit it to two rounds in the magazine per migratory waterfowl game laws.
The plug is a wooden dowel 8.75" long 1/4" diameter with two 9mm rubber o-rings about 1.5" from the ends. I believe the purpose of the rubber o-rings is to prevent the wooden plug from rattling inside the magazine tube. The o-rings look very similar to that rubber ring in the photo. I image if one came off the plug it could get creased from the magazine follower or spring.
So I will hazard a guess that what you have is a bolt over-travel limit buffer for a M41A Pulse Rifle.

That's funny

The part does not look like the Mossberg O-rings used on the limiting plug. You don't need to have a gun apart for cleaning in order for a damaged part to fall out of it. I am still thinking it is the small buffer ring on the Springfield SD's recoil system. I've included a drawing that points this part out. Certainly I could be wrong, but it may be worth the time to field strip and check it.

Hmmm. Well, I guess I could take it apart when I get home today and see about this. I don't remember a rubber ring like that being in the position in the past. Does that diagram apply to the original XD, or does it pertain to the XDM as well. I have the original.
The reason I thought it might have come from the Mossberg is because taking off the barrel exposes the end of the magazine tube where that wooden plug used to be. I thought maybe the ring was in there and then fell out of the hole when the barrel was off.

digital calipers
can, for the princely sum of $12, measure your mystery part or group size in mm. If you then punch the mm/inFt button, the "English system" equivalent magically appears.
Alas, there is no button for internet groups. For that, I still have to invent my own "conversion" factor.

Whenever they say that, I always wonder if they're talking Imperial pint or American pint. And whether it's a dry pint or a wet pint.
I'm surprised nobody's bounced rcmodel for this:
I'm not surpised at the "firestorm." Metric v English always evokes an educational discussion regarding firearms. I'm waiting for someone to bring up "lines" for caliber --as in a "30-line rifle" --and "arshins" for the Mosin-Nagant rear sight range calibrations. And for someone to wisecrack about the word "mensuration." And maybe some archers could bring up "clothyard," as in "clothyard shaft.'''
Ah, what a jolly subject, this mensuration thing.
The "furlongs per fortnight" remarks remind me of the time a college buddy had bought an Austin-Healey motor car. Asked about how many horsepower it had, he responded haughtily in his best nose-in-the air phony British accent, "We don't use horsepower with respect to these motor cars. We use stone-furlong fortnights."

You can always use something common like a 9mm round next to it for comparison. I like the idea of the foot pad of the chair or a chrony. It looks like it's seen some gritty exposure.

delete.
The drawing is from the XD and not the XDM manual. Hey, it is just my guess but it is a part that gets hammered by recoil, acting as a buffer. At the size your talking about ,it would also seem to be a possible fit. Won't take long to check.
Mnrivrat:
I just checked it now. I took the XD apart and shined a light under the cap where that ring should be. It looks like it's still there. The cap would have had to come off in order for the ring to come out, and I can't figure out how to remove the cap. But anyway, the XD seems to have all its parts in place. That part you circled in your diagram is metal on my gun. I'm assuming the rubber ring, if there is one, is underneath that part.
The O ring I have isn't split so that it would have come off of something. I'm thinking very much that it's just one of the 2 O rings that came from the Mossberg's limiting plug.
