GRS BIFROST comes with more features and many clever details. It will be available for a wide selection of action inlets.

The great success of the GRS Berserk stock gave us inspiration to develop more rifle stocks in composite materials. The experience of many years and the new possibilities in strength lead to the new design of our brand new GRS SpeedLock II adjustment system (patent pending). This new adjustment system is once again stronger and, moreover, all added features come as a standard!

The new GRS BIFROST (from the name of the Norse mythology bridge between the Earth and Åsgard) is stronger, lighter and more versatile than any other GRS rifle stock that we have made before and is perceived as the logical add-on to our already existing and successful GRS product line, which of course be continued.

The main body of the GRS BIFROST is made of fiberglass reinforced composite materials. Our flush cup sling mounts allow you to quickly detach your rifle sling when necessary.

Rubber surfaces on the ergonomic grip and on the fore end area assure full control during handling your rifle at all times. And the new GRS SpeedLock II adjustment system just makes it the perfect rifle stock to body fit.
