TA01 Tanodized ECOS green tritium. It’s old so it’s a little dim but still lights up. I’m the OG owner of this thing. Bought it back in 2012 or so (might still have the receipt and box) It’s not seen a ton of hard use mostly the bench and static shooting. Any scratches are from getting pulled out of the safe. Glass is great. I put it in an LaRue LT799 with a tan KRAM spacer. I do have the original tanodized ARMS mount/screws still as well. I’m asking 1500 shipped/insured PayPal F&F, Venmo, or USPS M/O. Or FTF if you’re in Nor cal.
