For owners with 10 BAT-S/BAS-K. I called savage this morning regarding the stock on the 110BA. Its a modified magpul PRS2. They arent as of yet selling the stock alone. The guy in "technical support" said when its released it'll be around $600.
I am looking on sourcing the piece so I can just buy a PRS2 stock and install it. If you compare a picture of the 110BA, and a normal PRS2, you can see that the stock on the 110BA is straight in top elevation. If you then look at an off the shelf PRS2, its top elevation rises where it bolts to the gun. From the looks of it, you can take a PRS2, unbolt the "riser" front section and bolt on the piece from the 110BA.
Any info would be of help.
