Folding stack plate for foregrips
Adapter devices, apparatus, systems and methods of allowing a firearm to be supported by a foldable fore grip/gun handle. The fore grip gun handle can have bipod type legs that can be extendable from the handle. The fore grip handle can be just a vertical extension. The adapter can allow for the fore grip/gun handle to move from a fold back position along the bottom of the firearm so that the firearm can be easily carried, and the adapter to can allow for the handle to move down to a vertical support position beneath the firearm when the firearm is to be used. The adapter can also support a light in both a folded position and in a downwardly extended position, where light can be aimed forward, rearward to the side and/or pointed down from the firearm. The adapter can allow for a dual functioning component that can be either or both a fore grip and/or a light source.
1. A firearm fore grip adapter, comprising:
an upper plate member on the adapter for allowing the member to be attachable beneath a firearm, the upper plate member having a top clamp side and a bottom side, the top clamp side having clamp edges adaptable for sliding about picatinny rails underneath of a firearm, the bottom side having an indentation, the indentation having a front inner side wall and a rear inner side wall and a ceiling side wall; and
a lower plate member having a front end and a rear end, the lower plate member having sides with outwardly facing picatinny rail edges substantially perpendicular to the front end and the rear end, the rear end of the lower plate member pivotally attached to the rear inner side wall in the bottom side of the upper plate member, the lower plate member sized to fit within the indentation in the bottom side of the upper plate member, the picatinny rail edges on the sides of the lower plate member adaptable for supporting a fore grip thereon, wherein the fore grip moves between a vertical downward position for supporting the firearm to a folded position with fore grip adjacent to the firearm.
