The GRS Composite Riflestock "BERSERK" is probably the best synthetic riflestock you will actually find on the market! A super strong body with rubber surfaces on grip and forend gives total control and friction even in wet, dirty and cold conditions. The GRS "BERSERK" comes with bedding blocks installed. Therfore glass bedding is not required for this GRS Composite Riflestock. All GRS "BERSERKS" include the GRS Speed Lock adjustment system and a 0,5 inch GRS Limbsaver recoil pad as well.
