I would like to get a Double Diamond lower to build an AR pistol in either 9mm or .45ACP. So far, I've not been able to get any response from emails I've sent them and to a couple of distributors. I haven't tried calling yet (may do that tomorrow). DD is the one that is dedicated to a correct size for Glock mags. Emailed Mooney's a while back but also with no response. Anyone have any current information?
