I apologize if this is the wrong section. And I did use the search box up top but most threads were several years old. I've got a factory Daniel Defense lower I'm looking to sell and have no idea what it's worth. Some of the ones of GB were upwards of $600-700 depending on the stock. I've had this one for a couple years sitting in the safe. I think it was only used to zero a rifle one time. I know DD doesn't offer these any more but are they really worth the asking price on GB? Any help is greatly appreciated. Thanks.
