I'm reading an ad at Phoenix Investment Arms, about the artillery Lugers, and it says -
"Sometimes in examination people think the leaf site is bent. However, when raising the site to the full 800 meter position reveals a 7�° left movement. This design compensates for the rifling on the 200 mm barrel which gives the bullet a twist in flight and if properly adjusted will permit a corrected point of impact. Another example of Luger engineering."
Here's the URL -

I've only physically looked at one artillery Luger, and didn't really notice anything odd about the rear sight...
Is this true???
I'm not clear on how the 7�º "movement" is accomplished...Is the tangent sight axle offset??? Is the sight base itself cut at an angle???
On a related topic, I've read several threads here about Phoenix Investment Arms...Can their little historical tidbits be believed??? They do seem to have a lot of them...I was particularly interested in the dimensions they gave for the barrels on the "fat barrel" Lugers...
