Was on the hunt for these later imported Saiga sporter skeleton stocks in order to finish my Saiga SVD style build. Was brand new with Saiga inspection certificate. Stock included allen wrench for length adjustment. Length adjustment is smooth and easy and the stock locks up tight. SVD style cheek rest has an ingenious spring and lock system built in so you can flip it up to use with an optic or flip it down to use iron sights. Center fire also sells cheek rest replacement pads! (While supplies last). If you have a saiga sporter (I know, it’s rare these days) this is an incredible no mod stock you can put on.
