The Vgrip is an AR15 pistol grip with a picatinny rail on the back and bottom of the grip. This is a drop in part that allows a picatinny mounting stock to be attached to a bufferless ar15 variant upside down.

This allows the use of a gas mask or visor with a rifle whilst still being able to aim down the sights effectively. Purpose built gas mask stocks are far more expensive than the usual picatinny mount stock, and a little bit of inspiration goes a long way.

This grip is inspired by the СР-3 Вихрь, or SR-3 Vikhr (Whirlwind). The SR-3MP variant has a picatinny rail on the bottom of the grip which allows the standard stock to be detached and then installed on an adapter upside down. Instead of accepting a new stock, it simply inverts the old one.

Also included is a variant made specifically for the Pipe Hitter 37mm launcher, which has the grip angled forward 15 degrees.
