FULL CREDIT GOES TO AICAT101 AND HIS MOD HERE, I JUST MADE MINOR EDITS

in essence, while AIcat101's P90 integrated red dot sight mod is good, the reticle itself is incorrect with a few minor-ish mistakes alongside a unfortunately god awful turquoise filter
i've taken the liberty of not only fixing said sight with this mod here based on and referenced from several real life photographs, but also including several accurate/historical reticles for the sight

the reticles you can choose from are the following:

Red
-Fully red sight (circles and posts)
-Red inner circle and dot; black posts and outer circle
-Red posts; black inner circle, dot, and outer circle
-Red posts; REMOVAL of inner circle, dot, and outer circle (not accurate irl but some games depict it that way so i thought i'd add it as well)
Green
-Fully green sight (circles and posts)
-Green inner circle and dot; black posts and outer circle
White
-Day sight with white inner circle, dot, and outer circle; black posts
