Just recieved my mag back today. AGD does some fine work, good turn around time on repairs. A great reciept that documents exactly what was wrong and what was done to repair the problem, and they rubber band on a paper showing a series of chronos to show its consistancy....cool!
mine said "hi: #286.2 fps
lo: #284.7 fps
Why would anyone stick a reg on a mag, lol. their soo consistant with their stock reg valve.
