Replacement barrel for Baikal MP-18

[maint1517]

Im trying to find a replacement barrel for a .12ga Baikal MP-18.
Ive tried Numrich(out of stock),Buds Gunshop( nothing),Ebay,Armslist and Gunbroker(all nothing) I even contacted Baikal directly, they said they have never imported barrels for Baikal shotguns separately(????). I even tried looking for one for a Remington Spartan, ive been told the parts are interchangeable between the two guns. NOTHING.
If anyone has a lead on one I would really appreciate it, new or used.

Remington Spartan is a re-branded Baikal - they are the same guns. If you find a replacement barrel, first take it to a gunsmith to check locking lug engagement - with those guns there is rarely a part that will simply drop in...

Thanks Mizar. Never thought I'd have this hard a time finding one.
