Well, I put a lot of work onto this scope, and I hope you all enjoy it a lot!
The top of the scope has a range estimator set up for 30, 60, 90, and 120 blocks respectively. Just set up the flattest block within vision to fit within the corresponding block measures and you will have a very accurate estimate of how far you target is in block distance!
Next is the small circle to the bottom right-hand corner of the crosshairs. That is the "margin of error" for the current rifle trajectory decay. As long as the target you are aiming at can fill that circle completely, your shots will NOT miss. This way you can play it safe and guarantee your shots will land perfectly every time instead of taking a risky shot from being slightly too far from the target!
The crosshair itself is red to stand out easily a midst the most common colors you will find on the battlefield, and slightly transparent to guarantee it doesn't completely block out the smaller object you might be aiming at.The reticle is also only 2x2 pixles, ensuring the maximum amount of visibility within aiming while retaining perfect alignment with the rifles trajectory. The top of the crosshairs are left open so you can scan the battlefield without anything to obstruct your vision, and the small half circle is for easy target acquisition within shorter distances.
Lastly a second range estimator specifically aimed at enemy size and distances (both height and width), can be easily paired with the "margin of error" tool located above to help you further estimate the best way and time to attack your target. It can also be used as a distance estimator in retrospect if aiming at a relatively flat surface without any blocks to use as size indicators.
I have personally tested the accuracy and distances on a private server in a controlled environment with my size model (fiance) so I can GUARANTEE you all of these measurements are PIXEL PERFECT. That's an "Operator" Guarantee!
