The spigot fits the original and Versa-Pod style attachment bipods. It is very easy to install!.  Open up the bolt hole where the fastening screw is to be mounted to 5 mm insert the spigot into the Bifrost stock with the stopper facing downwards, towards the ground. Use the supplied short screw in the front Picatinny bolt hole to secure the spigot.  If you are using the Picatinny rail on the bottom front of the Bifrost stock, use the longer screw to secure the spigot. The GRS Spigot gives you easy to use detachable bipod mount, close to the core of the barrel. This will be giving you better control when shooting with bipods. Shoot straight!~

We continued our vision of “no tools needed” on the Height adjustable recoil pad option, the push button solution, ready to be installed on your excisting GRS rifle stock or to come with your new GRS stock. The option is made in hard anodized aluminium with stainless steel springs and screws. The full adjustment is 44mm from top to bottom and can be set in 4mm steps from zero to -16mm and to +28mm.

Fits all GRS laminate models, GRS Berserk and GRS Bolthorn. It does not fit the GRS Bifrost - which is delivered with a different height adjustable and canting adjustable recoil pad as standard.~
