This is a Handguard that i made for my VSS Vintorez made by Red Star (i got mine second hand but the guy probably bought it on Kotte&Zeller), but i dont know if it fits other VSS models.
I designed it as close as i could to the original one.
The rail is about 11cm long and the handguard has a very tight fit.
i used two m3x30 bolts and two m3 nuts (you might want to shorten the bolts to about 27-28mm in length)
