I found an IZ-107 S-12 24"bbl for sale on gilbertsguns.com for $439.95. I bought my S-12 from them 2 weeks ago, same model with the factory BHO, for $460.00 shipped. I am not affiliated with Gilberts in any way,i just bought my first Saiga from them, just passing on a find to anyone whos looking for a S-12. Good hunting and good luck, Justin
