I've had a Trijicon AccuPower for several years and the lower power illumination stopped working. I sent the scope back to Trijicon which was received by them on 7/6/21. I got notice from them earlier this week that they could not repair the scope and that they were sending me an upgrade to a Credo, free of charge. I received the Credo today and couldn't be happier. This was a 17 day turnaround, with an upgrade and communication all along the way. Great job Trijicon!
