Your magpul stock that you have in that picture will not work with RS Regulate stock adaptor. They made their adaptor for the ego magpul variant of the stock. So you will defiantly have to make your own.
yugo variant? I wasnt aware there was 2 type of zhukov stock. Anyway my first objective was to make my own adapter for this stock, so i just wont wait.. Thanks for saying and saving my time!
