GRS Bifrost Piston

GRS Bifrost

GRS has always been a leader in the development of innovative products and they can now proudly present the next generation of rifle stocks. GRS Bifrost comes with even more setting options and many smart little details. After the success of Berserk, GRS was inspired to manufacture more pistons in composite and also to manufacture the new SpeedLock II adjustment system which is both stronger and comes with more adjustment options.
The new GRS Bifrost (from the bridge that leads between Earth and Asgard in Norse mythology) is stronger, lighter and more versatile than any other GRS piston to date.
The piston itself is made of fiberglass-reinforced composite with a rubber surface on the grip and forend for full control in all positions. With the new GRS SpeedLock II, the following can be adjusted:
• LOP (Length of pull, length to trigger)
• Height of cheek rest • Height of the back cover
• Lateral slope on the back cover
The stock is prepared for picatinny rails on both the front and rear stock. Two are included.
