5 weeks in October 2013 on a M&P 15 Sport to change the upper for cosmetic reasons- the original barrel arrived with scratches.
7 days in November 2013 to do the bushing recall on a 686-1.
Tracking on both shipments was excellent. Because FedEx requires an adult signature I had FedEx hold both at the FedEx shipping center instead of chasing the driver. This has to be done with FedEx, not S&W.
Work on both guns was excellent. No problems whatsoever.
