It is more of a cool factor than anything else.
In reality, scent, movement, sky-lighting will spook animals more than a non-camoed gun.
Glare refection from an optic usually does more harm than the color of the rig if I was to guess.
Chuck keeps threatening to paint one of mine in pink camo, but had not thought of neon!
I love that is camo! You will reach so far out there on targets and game it could be neon and they wouldn't spook!
That is one bad looking boy...
