I'm not convinced that this is a .22LR barrel, but IF it is, it may be an enthusiast's attempt to shoot .22LR using all Luger components. Have to be single shot as the extractor notch would be for clearance only; no .22 magazine; have to use a dowel to poke out fired cases (think Liberator).

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.

It does look similar. It's definitely not 7.92 Kurz; not 7.62 x 39 Russian. Might be a .308 Winchester case shortened and formed to fire a ~.324" bullet but it's not anything I recognize. Can't be a longer cartridge (like .308 Win) or it would push too far into the chamber. Might be 8 x 57 Mauser case, shortened. Might even fit in a military bolt action rifle chamber in some way that I'm not aware of.

I'm waiting for my end mills [mail] so I'll look in COTW and see if anything looks similar...

Got this at a gun show back in the 70's or 80's.
