I have a Browning BLR that was a SHOT show exclusive from like 2007. Stainless and Mossy Oak Brush Dura-Touch. Damn thing is soooooo sticky that you cant let go of it.
Browning was replacing those defective Duratouch stocks with non-Duratouch ones. You should contact Browning for a replacement.
To the OP - Sorry, I don't know about any Sako replacements.
