The Low Profile stock is a vast improvement over the older BVSS

series....as mentioned it is a small shank action....which is most common...

All you need to change is the bolt face if you want to change to the 308 family

cartidges...the barrel is 9 twist...so you can shoot 50-77 gr bullets...yes it is a

Model 12....the DBM's are the newer 12's...very good investment...s/shots are

only available in the target series at this time.....
