So, for more flexibility with using higher powered optics especially in low light conditions, a 50mm objective lens is the best choice. Move the scope up and down to see how the disc goes in and out of focus.
Thankfully at 10x even some of the cheapest scopes on the market will resolve a 1. For regularly sized targets, lower magnification is not an issue.
The Nikon optics is preferred by most shooters because it can give you that high definition visual even at distances up to yards. The black FX-Moa reticle that the Nikon rifle scope has is also advantageous for our dedicated shooters. Typical ranges for steel targets are from to yards, and they are engaged from prone and improvised positions, often under extreme time pressure.
These are also generally the more expensive of the two options. In a nutshell, the purpose of AO is for precision. If you are just out doing some target shooting or like to do shooting sports or hunting within a range that can be met by a fixed parallax scope, this would be the cheaper and simplest option. However, if you are a tactical shooter like a sniper, or like to do long-range hunting or range competitions, then you would probably want to go ahead and purchase an AO scope with a good parallax adjustment.
Cutting back on that parallax effect is absolutely crucial when trying to achieve those long-range one-shot bulls-eye shots. Personally, I like having the side adjustment knob over the adjustable objective simply for the ease of use, but they are usually more expensive, so for budget purposes, the adjustable objective would be a good decision. Both serve the same purpose of eliminating the parallax effect.
Although it is not really considered a purpose of AO, having parallax adjustment capabilities also innately turns your scope into a range-finding scope. The adjustment has yardage numbers on it so you can set and remember approximately where you need to adjust for parallax at certain distances.
You should now have a pretty good grasp on what AO means for scopes, and if this is a feature that is necessary for your shooting needs or if you can live with a fixed parallax setting.

There are actually two optical systems in a rifle scope. The objective front lens focuses the target image on the reticle cross-hairs ; the eyepiece rear lens focuses the eye on the reticle.
Most eyepieces have a lock ring. Unscrew the lock ring a turn or two so that the eyepiece can be screwed in and out. Adjust the objective for infinity very far, often a small 8 symbol.
