The difference between 100M and 200M with M855 from a 14.5" barrel is right around 2moa so it's not gonna hurt you too much to just be somewhere in the chevron up close (I never got along with using the crotch as an aimpoint and just held over at 200 anyway). What I do is zero the optic (TA31RCO) at 300M (using the 300M aimpoint) and confirm where it hits at 200, 100, 400, 500, or wherever I can.
I do that because the chevron is somewhat imprecise and close enough for 1-200M work. The game starts to change out at 300 and beyond where small errors become big misses. Tune the sight up for the long shots and the close shots will take care of themselves.
