greetings & salutaions to you too,,congrats on your purchase,,take the replacement stock offer,,if they want the old one give it,,if not,,you'rre to the betterment of your goal.as for fixxing the stock,,,never tried cause it hasn"t happened to me,,you see,,someone tried to remove the stock by dismantling it,,,any removal of an M1014/M4 stock is removing the trigger group first then just spin it on or off,,,,,peace be with you
