I have a question. It appears that the scope has an adjutment ring for the rear lens. This one would focus the range you are shooting at. But, when adjusting it for a focused picture, the crosshairs may go our of focus. Some scopes, if you remove the threaded ring at the very front of the scope, have another ring under that, that can be used to focus the crosshairs. I have a Centerpoint like that. I wonder if these have that feature. Note, this is not considered an AO scope, and is not a feature that everyone knows about. This was pointed out on www.airgunweb.com.
I believe the factory specs state it is set for 50 yd parallax. It has a threaded retaining ring on the front element, but it appears just to keep it in a fixed position.
This is what you need to adjust for closer object. I turned about one full turn counter clockwise to focus down to 15 yards. The reticle still looks sharp.
looks like this "legendary little scope by Horton" is now out of stock at Natchez.
