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!
Just as the deer can suddenly materialize in the woods, "Therefore you also must be ready, for the Son of Man is coming at an hour you do not expect" (Matthew 24:44)
