I have two forends for a Saiga 12. . The first is a Tapco Intrafuse with rails. It was installed and I decided I didnt like it and never fired the gun with it installed. $35 delivered. Comes with adapters for .308 and the other rifle calibers.
I also have a Russian Wood forend for the Saiga 12. . I think they use beach wood. I don't believe these were ever imported into the country on guns. Same as the .308 wood stock guns used. Its for a Saiga 12 and I bought it from RusMilitary . $40 delivered.
Nothing wrong with either. I just ended up using a Galil wood forend.
