This is my second ACOG and the second one with problems. My first was in this thread https://www.m4carbine.net/showthread.php?p=446252#post446252 which Trijicon promptly repaired. My new one does not have the reticle problem but has a large black spot in the glass inside.
Please report back when Trijicon has addressed the issue and we will re-open the thread.
