Just wanted to give y'all a heads up. Last week I ordered a UTG quad rail from combathunting.com SKU:MNT-HG478SA . It is listed as fitting the AK47 and specifically says it fits the varients Saiga 223 and 7.62 ....well it doesn't. The top rail is too small to go over the gas tube. They list another one for AKs with oversized gas tubes, but list the model shown for Saiga's. I have e-mailed their customer service dept to see whats up, but figured I'd save someone else the hassle.
For what it's worth, this is a really nice looking solid feeling quad rail, just hope that they have one that will
