I have a side mount that fits my Sagia .308, it is the BP-01 MTK-83 you can see pics on Tantels web sight. I also have a top cover that has an intregel rail very securly fastened to the top, it also has stablizing screws in the back. I believe you can attach side rails also (I don't have them).
I would like to get $25.00 dollars + shipping for the BP-01 and $15.00 dollars + shipping on the topcover mount.
I would also trade for a Nato length polymer black butt stock and pistol grip with the bolt and the nut.
I can e-mail pictures....
I would also throw some cash in for a stock and p-grip, or pay the shipping wich-ever works best.
