I bought this folding Troy BUIS with the dual aperture new and mounted it to one AR. AR got sold and the sight has been sitting in my parts bin ever since. Practically brand new with no scratches or defects of any kind. After tax and shipping these are running around $140 new. Firm on $100 cash. I can meet Saturday, Sunday, or Monday at Cabelas. Email at tylercotton10@gmail.com if interested/questions. Thanks for your time!
