We feel Berserk stock is a perfect addition to our existing product line. The reason we want to deliver these stocks is that we know the end users have asked GRS about synthetic stocks since we started with the laminate stocks in 2012. A lot of end users would like to have our ergonomic and adjustable features, but they want them to come in a more tough and durable material than the laminate.

This product is also in a lower price range and it comes in right hand configuration only.

Adjusted dimensions in the grip, fore end and length will fit most People.

The rubber grip and fore end surfaces gives you a firm grip even in wet conditions.

The Stock comes with pillar bedding Blocks made from 65% glass fiber as standard.

Recommended torque is 5nm. 

The GRS models Berserk, Hunter and Sporter came with the new and updated GRS SpeedLock system in March 2017. For the time being, the GRS models Hybrid and X Eater will not be available for ordering with the new system. The GRS Bolthorn will continue as is, and will not be updated.

The new adjustment system locks on the maximum LOP of 30 mm.

GRS Berserk is available in the following inlets:
Tikka T3 (all Calibers)
Howa 1500 SA/ Weatherby vanguard SA
Remington 700 BDL short and long action
Savage 12 and 16

For Savage 10 please contact your Savage Arms dealer.

System inlets list


  • The material is a 15% fiberglass reinforced Durethan.
  • The composite stock will be made in one size, black colour and in right hand configuration only.
  • The grip and forend is 5% slimmer than the Sporter varmint.
  • LOP 33.5- 36.5 cm. This size and LOP is the ideal based on the feedback we get from end users.
  • The surface under the rear stock has been lengthened so it will work better with the use of rear bags during prone shooting with bipods.
  • The grip and forend has rubber grip surfaces for better friction in wet conditions.
  • The surface of the rest of the stock is also with a texture so it is very easy to grip.
  • The stocks have pillar bedding in them as a standard made from 65% glass.
