Hello All,

I have an IZH 43 Baikal 12 ga 2 3/4" SXS with screw in chokes.
Tanfoglio of Italy offres conversion tubes for this gun.
Sold through EAA in FL.
The caliber I bought was 45-70.
The tubes consist of a rifled tube turned at the breech to 12 ga case dimensions
with an extractor, held in with a wire clip.
At the muzzle it is threaded and a raised ring feature has some slots cut in it.
It came with 2 sets of excentric bushings that depending on what slot they are installed in
changes the regulation.
This is then followed up with an O ring and knurled nut to keep everything put.

I have often though about getting a set of ER Shaw 20 ga rifled barrel blanks.
And having a smith copy the design onto these blanks, voila !
20 ga SXS DR.
I have to hunt with a shotgun due to DNR regs and that would be perfect.
They really are cool conversion tubes.

Very similar to the obove idea except starting with barrel blanks and giving some adjustability.
