From the very beginning, we at GRS decided that our rifle stocks should be add adjustability to their ergonomics, and that this adjustability should be activated in the simplest way possible - the GRS "click".
The patented Speedlock system was developed for our first models - it is silent, easy to use, precise. Press one button to change your Length of Pull as you need, press another button to change the height of your cheek-piece. One push, one adjustment - instant, and simple, with no need for any tools. Our single sided Speedlock system is installed on all our Birch Laminate stocks, and on our Berserk.
THE SPEEDLOCK 2
As our portfolio progressed, it became clear that we could make good use of a system that could be accessed from both sides of the stock, with your right or left hand, and that would be even more robust in extreme conditions - may it be from the instant forces of the recoil on larger caliber rifles, or from hunting and shooting in extreme weather and wetness conditions. Our Speedlock 2 system is presently installed on all our composite stocks except the Berserk.
