And Why you should Get One
First off if you’re not familiar with the Vortex Scopes it is a high end piece that goes well with anyone that’s into long range shooting. The Vortex Viper PST 2.5-10×32 is a FFP scope, there are some differences to a second FFP. In this segment we’ll keep it real simple.
Frontal Focal Point – First focal plane scopes are specifically designed for “tactical shooters and hunters” where the distance to target changes and is often unknown. FFP scopes place the reticle in front of the erector.
The first focal plane reticles do not grow or shrink in size as magnification increases, but it appears they do. The reticle is being magnified to match the magnification of the target. The reason this is important to tactical shooters are many. First and foremost tactical shooters and hunter tend to use mil scales to calculate bullet drop and wind calls.
The basics of a first focal plane scope, the mil scale is the same at 2x as it is on 10x. So the scale is always the same. Tactical shooters are also speed based shooters – either need to follow up quickly or engaging the target immediately. So it means they may not have time to calculate the difference in magnification and the difference it makes in mil scales.
Vortex Viper PST 2.5-10×32 FFP Cool Stuff
Reticle focus is at the rear
Another feature that seems to stand out is the reticle brightness stands out more than other PST scopes. This may be due to the smaller lense bringing in less light so that it allows the reticle to light up more. (based on HighJaker86 Youtuber observation)
