Tried to order a MagPul M-Lok QD sling swivel socket (MAG606) for my SCORPION MICRO, from Amazon along with a bunch of other stuff first week of November. First, everything else on my order shipped except for the MAG606. Finally got notice that the MAG606 had shipped with the tracking info and within 24 hrs the order had disappeared, apparently lost/stolen before making it to the shipper.
To Amazon's credit they didn't skip a beat, they immediately re-filled the order and sent another tracking number. After the second order had been shipped and tracked for about 5 days, it once again just disappeared from tracking. After 7 more days I was given the option of a refund or a reorder with the caveat that the MAG606 was now out of stock. Refund requested and received within reasonable time.
Third time is the charm right, placed an order with Brownell's for the MAG606 along with 1 other item and against my own good judgement, decided to give them one more chance at using their "FREE SHIPPING" option. Big mistake. To Brownell's credit, they did fill the order and ship within 2 days but the "FREE SHIPPING" option is UPS SUREPOST which is the worst shipping option possible. UPS did their job at getting the order to the Urbancrest OH transfer point to USPS, which is about 50 miles from my house. However, USPS then shipped the item right past my local post office to Cincinnati OH, which is about 30 miles from my home, E of Dayton OH. Looking promising, WRONG. Next tracking entry, the item is in Manchester MI (WTF), and it's been there since Dec 2, with no signs life.
This quest to obtain MAG606 began the first week of November but I'm beginning to believe that the Mag-Pul MAG606 is cursed or is destined for the Bermuda Triangle.

Sorry for long vent, I'm retired, bored and have been waiting for the MAG606 to reassemble my MICRO, after taking it apart to hopefully fix the loosening faux suppressor issue for good.
