Assuming you're talking GNAS - Rule 206/206a does not prescribe D-shape, only that
"The bow shall correspond to the traditional form of a longbow which means that when strung the string may not touch any other part of the bow but the string nocks".
So as long as they don't touch the limbs - could be American Flatbow.
...but it is a hybrid...
NFAS would not accept it as AFB - hasn't got D-shaped limbs! Would go in one of the
recurve styles
depending on arrows, hook/release, ...
Think IFAA also would reject as
longbow due to limb shape.
