I had posted in the thread started by 45Ron about a 9mm RRA upper I had purchased that would not fit my receiver and I had never been able to use.
I owe it to Steve and RRA to update and give the outcome.
I had been given a return authorization from RRA to send my upper back but I had not shipped it at the time because I am not convenient to a drop off location. Steve contacted me and he worked out an arrangement to get the upper back. ( this upper had never been installed and I had never fired a single round through it). UPS tracking was much to be desired and it took talking with their customer service and several E-mails to Steve and RRA to confirm that the upper had indeed been delivered to RRA.
My upper was returned to RRA on Dec. 9th.... in about eight working days..... It was returned 2nd day UPS but UPS took like 4 days to get it to me. (shipped on Dec. 15 and delivered on Dec 19 at 7:40 P.M. but the weekend was involved). I put it together that night (everything fit. Hammer , mag block, buffer, and upper) but I had to wait till morning to try it out.
The 9mm mid-length flat top upper did and has continued to run 100%. It only has about 100 rounds through it, both fmj and hollow points. Only down side is this upper has a gray-black, almost phosphate finish where the first upper had a slicker, almost black teflon finish which matched my lower better. I will also say that the upper seems very accurate, but I have only shot it off hand so far. It IS great fun to shoot!
Just wish I could find mags at a good price.
I do appreciate what Steve did in taking care of the problem!
