Can any identify this part?
 

Got a few of these accidentally sent to me. What are they for?

The only thing I can think of is a flash hider keychain adapter?

Ah, that made me notice it has negative threading. I will see if it is 14 mm negative.

Could also be weird barrel plugs.

They are 14mm negative thread so you can make a silencer or flash hider key chain. I don't know what else they are for, though. Any other ideas?

I'll bet it's for a flashlight but how about saying where they came from?

It looks like a barrel plug for a VSR...

I did a large order with my chinese supplier. They must have fallen in one of the boxes while they were preparing my order.

How did I... What?

Airsoft buttplug.

Threaded for AEG users.

Now that I'm looking at it, it looks like a buffer tube plug for an AR. Remove your rear stock to shorten up the gun, and the ring is for a sling. Maybe it's too small.

I know what you mean but it is too small for that purpose. It fits the Diablo Flash hider perfectly. The threads go in and the Diablo has a groove cut out that fits the rim of the unknown item. Beautiful keychain, LOL.

It's surprising at the number of people here who don't know what that is.

It's a Canadian quarter, if you get four you can exchange it for a loonie.

It's clearly a paper towel

It looks like newer version of the un-screwing mechanism for the PSG-1. If you wanted to add a silencer (or the M82 flash-hider), you need to unscrew the end-cap of the barrel and thread it onto the inside.
