steady......steadyyyyy....aw ****Off topic - had a friend with a DI RMR on his rifle, had it in the safe forever, pulled it out one day and it was leaking like ninja turtle oil into where the screws go. He contacted Trijicon and they had him like triple bag that thing and wanted it back ASAP. Never seen warranty move so fast. This was 9 months ago and he doesn't have an arm growing out of his forehead yet.
