LPVOs and prism scopes both have the same restrictions with eye relief and an eyebox. The difference is that one optic (LPVO) has variable power magnification, and the other (prism) does not. At that point, you have to consider whether it’s actually worth your time to even bother with a prism scope when there are so many quality LPVO options on the market that do a better job. At least that’s my opinion on the matter, and why I run LPVOs.
I have used Trijicon, Leupold, NightForce, Kahles, and a myriad of other LPVOs, and I’ve also run prism scopes ranging from the garbage Leupold Prismatic 1x to the Trijicon ACOG TA01 4x32 I carried in Iraq on an M16A2. I’ve also tried options like the Leupold HAMR and other optic styles like the Elcan SpectreDR. Prismatic scopes served a purpose once, but now they’re obsolete with all the LPVO options in every price/quality category.
For the LPVO, I also don’t buy Chinesium scopes. The LPVO needs to have daylight bright illumination (RDS bright, or pretty close to it). After that, the glass comes second, then magnification, then everything else. I don’t care who makes the scope- if I can’t use the illumination in broad daylight with bright sunlight, I don’t want it and I won’t use it.
The best LPVO I’ve owned is the Kahles K16i 1-6x.
The best LPVO I’ve ever tried is the Vortex Razor HD Gen3 1-10x.
The best LPVO for the money is the Trijicon TR24 AccuPoint 1-4x
