Inspired by Smoky baer i dicided to make my own stock adapter. I too always wanted a pistol grip stock but could not justify the cost.I cut the buffer tube threads on the lathe because i did not want to spend $65.00 on a tap only to use one time. It is secured to the stock with J-B Weld, threaded studs and a 1/4-20 socket head screw. The way it is mounted the rest of the stock will fail before the alum. adapter will, this thing is'' bomb proof''FRG1 I have a Magpul CTR Stock and Magpul MIAD grip on order to complete the project. More pics when the stock is completed.
