I looked at the Bifrost for my Tikka CTR.
I have shot a couple of rifles with these fitted and, they are good to handle, not cold in Winter, not too heavy to stalk with (for me) and very adjustable. A very nice stock.
However I bought an MDT Oryx instead, I have a long thin face and the cheek weld was not as good for me, otherwise I would have plumped for the Bifrost. The Oryx is heavier, cheek rest not adjustable as standard, but a simple job the resolve and it’s more rigid, with options for Arca Swiss or Picatinny on the base.
