P39Q had the N-3A or B gunsight which was shipped with a 70Mil ring and dot, and a fixed reflector head mounted to it. Later in the war some were upgraded with the A1 tilt able head for bombing but, the reticle was still a 70Mil ring and dot. You could now tilt the head raising or lowering the reticle.
That's why I include the N-3 30Mil and 70Mil with ladder ramps because we don't have an active tilt head for any of our gunsights. The 5Mil ticks represent the tilt dial's selections from turning it to tilt the reflector plate by fractions of degree. Turns out they were about 5Mil movements in real life.
I'm sorry but, the historic gunsights are not point and click. In ww2 they never were. Each pilot had to practice using the given gunsight enough to get good shooting with it. Even the active reticle K14 had to be practiced with and it was not a 100% kill solution. It simply improved the ability to actively predict the point to shoot for in low G turns. That was one of the hardest skills to learn for 80% of fighter pilots in ww2.
You may have noticed shooting past 200 yards in this game has many down sides requiring practice to over come them.
PS,
Offline flying at 300 IAS auto level on full zoom. Using the 70Mil with ladder. Bring up the target and fire at the ranges you are interested in. Take screen shots. Then take a copy of the N3B70rmp and add numbers next to the tick marks related to your shooting at the offline target. This is ideal for air to ground with the 37mm. Air to Air at least you will have an idea of the drop, not the lead which practice against the drones will help. Just remember your convergence for the 37mm will matter after you modify the gunsight. I used to create custom K4 gunsights for individuals. I learned the hard way to ask them what their convergence was before doing this testing. One persons personal gunsight is a personal reflection of how they perceive what they are seeing. Practice will always be required to make it a point and click solution.

Sometimes when you goto full zoom on maps your gunsight structure disappears into the target. Night time works better to see the target and your gunsight structure.

I use 01:00. 12:00 resets to noon.
