The appearance of this Norwegian stock probably looks familiar to you because one of the earlier models of these stocks was used by Savage in their Model 10 GRS rifle. GRS makes a wide variety of such stocks. The latest iteration of their polymer stock called Bifrost was introduced at IWA 2018.

The GRS Bifrost stock is made of glass reinforced polymer. There are additional rubber inserts in the grip and forearm to ensure a more solid purchase. The enhanced GRS Speedlock 2 adjustment system allows adjusting the length of pull, the height of the cheek piece as well as the height and cant of the butt plate.

The stock also features short Picatinny rail sections mounted on the very front of the forearm at 3, 6 and 9 o’clock positions. These rail sections are removable and there are QD sling swivel sockets under the rails. The stock comes with one such rail, but additional rail sections are available for purchase separately. Another rail section for mounting monopods is located under the toe area of the stock. There is also a rear QD sling mount near the monopod rail.

      @spike1984 They never removed the swastika. Nor the eagle. They grinded the serial away, then stamped it with their own serials.

    None of the pictures, info seem to say but if they don't have an Aluminum bedding block that goes through the forearm that's an instant dealbreaker unless it was half the price. The adjustments look nice, but for $200 more than the KRG X-ray stock. Even the new KRG Bravo stock has a fully machined bedding block and is $350.
