The reticle on FFP scopes might be difficult to see and utilize at low power settings, according to one critique. With some reticles, this is certainly the case. Scope makers have attempted to solve this in a couple of ways. One way is to make the crosshairs thicker outside of the center area. At lower power levels, that larger line is easy to pick up, which is especially useful in low light.
Illuminating the reticle is another option. This adds weight and cost to an optic, yet it can save a shot in certain situations. Between each level of illumination, the best illumination systems have a "off" setting. This allows the shooter to instantly turn off the illumination, regardless of the illumination level.
FFP reticles are measured in milliradians (mils) or minute-of-angle (min-of-angle) (MOA). It is up to the shooter to decide which system to utilize. In the following article, we'll go over the basics of mil and MOA reticles.
