Frequently Asked Questions

What are the key advantages of the Primary Arms PLX-C RDB LPVO?

The Primary Arms PLX-C RDB is praised for its lightweight design at 17 oz, excellent 1x performance comparable to a red dot, and the crucial 'Red Dot Bright' (RDB) illumination for daylight visibility. It also features an auto on/off 'Shake Awake' function for battery conservation.

How does the Primary Arms PLX-C RDB compare to the Nightforce ATACR?

The PLX-C RDB is significantly lighter and approximately $800 cheaper than the Nightforce ATACR. While the ATACR might offer slightly superior glass quality at higher magnifications, the PLX-C RDB provides better 1x performance and overall value for general-purpose use.

What is the main weakness or quirk of the PLX-C scope?

A notable quirk of the PLX-C is its wide focus range between 1x and 8x magnification. Users may need to adjust the diopter to achieve maximum clarity at high magnification if the scope is focused for 1x performance.

Why is daylight bright illumination important for LPVOs?

Daylight bright illumination is essential for First Focal Plane (FFP) LPVOs because the reticle can become difficult to see in bright sunlight, especially at 1x magnification. It enables faster target acquisition and a more intuitive shooting experience.
