I don't know how effective a .22LR would be using a center-fire firing pin, but many many years ago I picked up the sub-caliber insert pictured below. It is smooth-bore .22LR, and the steel body is as follows:

- .470: dia body
- .354" dia neck
- 1.212 body length
- 1.735" OAL

I don't know what cartridge chamber this was intended to be used in; obviously a rifle, but way too short for the .308" Winchester.

But somebody thought it would work. It's very well made, not something turned out in a basement. I'd say production, maybe even gov't issue.

So this barrel in the eBay auction may be someone's attempt to center-fire the .22LR with 'standard' Luger pistol minus barrel.

IF it's .22LR...

That contraption reminded me of this, although the dimensions differ.
