Not quite True bud,
I've the N550 and i Prefer it to the NS and nitehunter offerings as it's more natural like a scope to shoot with,
Also both My Rapids have weaver rails so no Messing about re-zeroing with the Day scopes off in seconds and changed over
and the only difference between My two rapids is the Calibre .177 & .25 so a quick scroll on the side wheel menu and i've changed both axis Y= and X=
which is your Up and down on Your reticle which is written down for both cals, also i like the option of changing reticle types which is a bonus.
