Thank you for asking. Status is ZERO progress. I have been busier than the proverbial guy at the contest, and have not even looked at the boxes of parts for least a month... I need more time... More money would also be good... Actually, more money would be really good...
I've got to look at everything and make sure I have what I need. I think I am still a couple bolts short of the necessary quantity... Maybe also gas tubes and sights... And I am still waiting on the 5.56 bolts from @Robocop1051 's contact, which should lead to a couple of AR-15 builds... One in .300 blackout, and the other in 5.56... Sumbitch... That means more uppers, lowers, barrels, handguards, parts kits, triggers, sights, gas blocks, gas tubes, buffer tubes, springs, and fixed length stocks... I'm gonna drop another grand and a half before I'm done, and I don't even have the fancy optics piced out yet... Yes, more money would be really good...
Oh, and I have to talk to CA DoJ and get serial numbers squared away. If I gotta get those, I might as well build the AR-15s at the same time. Then a camp out at the @DNP ranch sounds like a great time. Maybe we can make it happen when the temperature differential is enough to inspire you to drive west...
On the bright side, I did suggest a work buddy get on here and check out this forum... Dan is a super cool guy who shoots and reloads. He likes the idea of an AR style .338LM / .500 blackout, and should really meet Rob at some point...
