Tac-D 37mm Stock Adapter. This adapter triples the utility of the Tac-D; turning it into a shoulder mounted launcher in minutes and without a stock it becomes a long-barreled pistol. The adapter uses the alignment recess in the rear of the Tac-D receiver to assure accurate positioning so that any AR compatible stock can be used. The pistol grip is AR standard too. Comes with hex head oxide finished mounting bolt AND hex wrench for installation. AR shoulder stock and vertical foregrip are not included. Note that neither the buffer nor the buffer spring are necessary for use of the shoulder stock.
