Starting this thread to avoid derailing another thread further....
I would like to hear why you think this is needed.
Why is it important to you to have an adjustable parallax feature on a LPVO considering what their basic space in the tool box is cut out to be?
I have a couple of 1-8x ATACRs mounted on 5.56 rifles used as loaners on certain blocks of class work. They have been performing excellently. Obviously they do not have adjustable parallax.
I just put both rifles in a tripod and tried to see what the observable parallax was at different distances. Both scopes were set at 8x which should have maximized any parallax between target image and reticle. My 2 scopes seem to be factory set for zero parallax somewhere around 100 - 125yds with little or no observable shifting. Maybe someone that knows for sure could chime in with what the factory setting is on these.
When viewing objects in the 50 to 65yd range, there was parallax present but very minor. I'm guessing around 1.5-2 MOA at most (remember that 2MOA is only about an inch at 50yds).
I saw zero reason to check closer than 50yds because I cannot think of even a remote reason why a user would have an LPVO cranked to 8X (or 6X or 10X whatever your top end is) at closer ranges. I don't give a shit what parallax is present in these sights at 1X and inside 50yds.
When viewing objects at 250 to 550yds, the parallax was once again present but seemed to be no more than 1 to 1.5 MOA at most. This is with very exaggerated shifts in head position from one side of the eye box to the other to the point of having no view.
These are LPVOs and meant to ride on carbines, so I didn't attempt to observe anything past 550yds even though I could lase out to 2,740.
To add an adjustable parallax feature into these type scopes, the design would have to incorporate a good bit more moving parts that would increase the cost/sale price, increase potential failure points because of the additional external knob, increase potential vacuum leak points and increase weight.
Having an adjustable parallax on this type scope/rifle combo throws the opportunity for the user to have the damned thing adjusted completely on the opposite end of what is needed if the rifle were needed to be deployed in a hurry (remember it's a carbine/battle rifle not a "sniper rifle".)
All of this in an optical sight that we are already asking to be combat tough, reliable and affordable. To me the ATACR, Razors and NX series of LPVOs are the top of the food chain in delivering a usable optic across wide spectrums of use and abuse. Both families of optics have the covered and low profile turrets, basic reticles and minimalistic exteriors that help keep them bomb proof.
When taken in the context of the text in bold above, I personally don't think the juice would be worth the squeeze in adding an adjustable parallax feature to this class of scope. In fact, I would consider it a negative.
Convince me otherwise...
