What is a left AO?
Oh, the side focus. Gotcha. I never liked the NXS illumination control. It comes from the factory set very light. First check the battery, then while the cover is off, twist the screw with a small screwdriver and see if the reticle illuminates. Finding a decent setting is an exercise in futility.
Parallax is a phenomenon engendered by having the objective focused on a different focus plane than reticle focus plane. This situation is corrected bye one of two methods: An adjustable objective (AO) where you actually focus the objective by the simple expedient of twisting the objective lens; or a side focus which involves moving a focusing lens located between the objective and the first of the three focal planes in a riflescope. The side focus knob, located on the left side of the riflescope is the one that adjusts the focusing lens.
This is also one of the big differences between the NXS and BR versions of the Nightforce riflescopes. The BR series has the AO, and the NXS has the SF. This is also why lots of people reported the BR model as being brighter than the equivalent NXS model. The NXS has an additional lens and therefore greater light transmission loss. The Nightforces never had a reputation for high light transmission values. Coatings.
Do you know the exact model name of the riflescope to which you are referring?
i was shooting a friends NXS and I told him to turn on the reticle and he said HUH?
he got it used and I tried to push/pull the left AO and didn't move??
no light or is it seized or somewhere else or none?
what am I missing?
Illuminated Reticles
"Most Nightforce scopes are equipped with Illuminated Reticles"
The Nightforce catalog states all NXS scopes have illuminated reticles.I am trying to get a pic of it and we just got together for the weekend and shot some 500yd+ tannerite into the darknessSunday night.
I have a 5.5x22x50 NXS and my light works, his side knob looked more like the compact not the NXS ?
most??? he bought it as a used/ pre owned package, 300RUM 210 Berger McMillan stock etc....it was sweet. He thought I was nuts telling him to turn in the reticle?
I didn't have my cheater glasses and it was dark, they left by AM...sorry, that's all I got without a pic.....

Look online and see how to replace battery. If it has a battery, it is lighted. That might also show why you can't pull the knob out. Mattthat's what I needed to know, thank you!
