Anybody know what this is?

I was originally thinking Agassi block with integrated rails, but it clearly goes up against the slip ring and I don't see how even an integrated gas tube would be long enough.

I'm interested in finding out what it is too.

Yeah, there's no tube inside the thingeemajiggy, and no way for gas to get through it.

The "nipple" on the end looks like a gas tube, but I don't think it is. Just a pin or something like that.
