AOA has always been great for me. Bought a couple of guns with them and never an issue. Even sent them my Cricket II as it wasn't cycling the mag regularly "after" Kip spent a good 20 minutes on the phone going over pic's I had sent to show them what was going on inside the receiver block. They had to order parts from Kalibrigun to complete the repair and still only took a few weeks. Great service and a bunch of good guys!
