Ranger Abell9, I have owned several types of Leupold scopes.
All variable target type. They all seem to have a narrow margin of eye relief tolerance. Which for me, even if my stocks length of pull was set to my size I had to find the
small sweet spot to fill the ocular lens with a borderless picture.
I have no experience at all with range finding. I do know the Leupold factory scopes reticle is in the rear focal plane.
I believe, and someone may know for sure, that Leupolds must be set at 10x magnification to allow reticle rangefinding to be accurate. Premier Reticle Leupold's are available, at least when I purchased mine, from SWFA as mentioned by Veteran borebrush.

The Premier Reticle is etched and placed in the front focal plane, which allows for reticle range estimation at all magnification. Leupold factory reticles are also wire type and may break. Which sounds like a minor consideration in the varied distance described. The eye relief tolerance of the Leupold is the only thing I ever found to dislike of them.
At a visit to
Cabela's (scope page link) store near me I found a Zeiss american assembled scope that felt pretty solid. Regarding the windage and elevation clicks, and weight. The most outstanding characteristic was the broad range of eye relief. I was able to maintain a full ocular picture with maybe an inch of movement or more. Pretty generous considering the Leupold I was used to. Zeiss Conquest 1" Riflescope in 6.5-20x50mm was the model I was looking at. They didn't have the Mil-Dot in stock, but was available to order. I never purchased the Zeiss so I can't speak of it's real shootability, only of the eye relief and picture quality.
In summary, I liked the eye relief tolerance of the Zeiss over my Leupold's. I think it would go a long way to relieving some eye strain associated with the few hour durations of bench shooting time I was conducting at that time. I know the 1" tube was more light restrictive, but the glass quality seemd very good, maybe not enough to overcome it directly compared to an off brand 30mm however. The price of the Zeiss was comparable to my 6.5-20 50mm LR/T scope from Leupold as well.
I never owned a Armalite myself, I did have an Stoner SR-25 that I traded a Steyr USR for at one time. It's comparable as it's a box fed .308. I enjoyed it a great deal, but I preferred my 700 Remington's accuracy so the SR and I parted company. I just couldn't get the accuracy out of it I enjoyed from my bolt action.
Not alot of info, but I hope it helps. Enjoy your new rig Ranger Abell9.
