What the heck is it.

I got two of these and haven't a clue what they are. They're dated around 1970.
They resemble a grenade launchers but the sight elevation can't be set.
It has whitish squares that may have had tritium that's long expired.
I think they might have been stuck on the end of a machine gun for night sights but I have no idea what.
The ID is about .870".

Don't have a clue but wanted to say, Welcome to the forum.

I am sure you will find your answer here.

That inside diameter suggests it might have something to do with a shotgun.

No, I dunno what it is.

Great call,

For those others interested.

Thanks everyone! I was racking my brains on that one. I was lacking the right search terms for an image search and there was no part number on it.
There's some more stuff I can't identify I'll eventually get around to asking about in the future.

Thx bannockburn,

The tribute goes to the Forum. I asked the same in Feb.15. 2015 here:

I got the right hint here and that is where my kowledge comes from.
Really a great community.

I bet they paid LOTS of money for them.
