I signed up for the email notification for the Magpul ACR Folding Stock thinking at the time it would be months before I might see a response. That was on a Friday. The next Monday there was an email in my box notifying me that there was stock on hand. Shortly after ordering, I also received an email from Dan Haga, asking if I'd like the Bren 2 Adapter I'd also ordered, attached to the stock. That's top notch, personalized service you don't see too often in this day and age. Superior product, backed up by fantastic service and a personalized touch. Truly appreciate the extra effort Mr. Haga.
