Upgrade ANY Merkel Helix with the NEW SpeedStock! Viking are pleased to announce the release of the SpeedStock which means that any Merkel Helix can now have the revolutionary SpeedStock as seen on the Merkel Helix Speedster. The SpeedStock, featuring Omega grip, enables faster reload and an automatically adjustable stock comb that can be adjusted at the push of a button. The new SpeedStock eliminates any obstruction during reloading and fast bolt action. The thumb slides as if on rails along the ergonomic stock shape into shooting position on the OmegaGrip, as well as out of it when reloading.
