Ordered this sight directly from HHA. It is a 2008 Brushfire XL5519. It has an extra-large sight ring, .019 green pin, rheostat housing and 10ft. of fiber optic wrap. This sight is by far the best sight I have ever owned. Within 3 shots, I was dialed in and within 10 shots, bulleyes at 35 yards! I'm shooting a guardian and its only 2.5" high at 15 yards and dead on a 35! Not to much guessing there. If you are thinking about a one pin sight look no further than HHA, they are awesome!
