I have a Trijicon TA11F (3.5x35, red chevron, dual illumination, .223) in excellent condition. I shoot my AR only a few times a year, so it has not seen much use. (I don't remember when I bought it, but it is at least five years old. The serial number is 8197 if you want to check with Trijicon.) Pictures are available.
The price is $875, including shipping via UPS Ground. (The price is $850 if we do a face-to-face in Houston.)
