Zombie Barrels charged me, so they are processing me order Rainier Arms on the other hand..... ordered a WOA Charging handle 20 bucks, they had in stock. Registered and added a ship to address. They sent me an email confirming my order, then sent one saying they needed a copy of a scanned ID to prevent fraud since the Bill and ship address was different. I sent them an email saying I have never had a problem with MidwayUSA, Brownells, SGAmmo, Zombie Barrels even or Amazon, and if they could not process the order as is, then cancel and I will not due any business in the future with them. Tom at Rainier sent me the email about the ID, I sent the reply, all Tues. Today I got an email from Rainier, the processed the order. Got a second email from Tom to confirm that the order has been shipped with a tracking number. Sent a reply stating they need to at least put a notice on their site about the address thing, and while there was a hiccup, I understand the company policy but they need to make it clear. So while I was PO'ed they took care of it, so while not a non-fart smooth transaction, in the end they solved it. I would warn people about the issue but would not tell someone not to order.
