I spoke to the guy at MetroShot he has had difficulty trying to contact everyone and says he has the lowers.
Here is the email I received from him:
Yes, glad you found me - because I could not locate an email from you. Your lowers are here from LAN World - they arrived yesterday. Please stop by Today Saturday 9a-4pm to inspect your lowers and start the DROS.
If you can not stop by Saturday, you can optionally go to the Ventura Gun Show on Sunday to start the DROS (not view the lowers as they are at the store in San Fernando).
Can you do me a favor and notify people on the CalGuns board and AR15 forums that the first batch of these AR10 lowers did make it to Metroshot ? We have others that were packed in the same box and I can't get ahold of any of these people....
