Bipod adapter set GRS Spigot

With this GRS Spigot bipod adapterset, which consists of a GRS Spigot and the GRS Spigot adapter, a GRS bipod can be mounted to a Weaver/Picatinny rail quickly and easily, underneath and on top of a rifle. This enables the GRS to be mounted on top rails as well. For this, one small alteration is required: undo the hex screw in the adapter, rotate the Spigot 180° and fasten the screw again.
