I use a 11-87 SP which I have not camoed at all and have never had a problem with it spooking birds.

Now as for the black stock think of this.

It is tucked into your shoulder for the shot - and you are pointing straight onto the bird - how the heck will camo help you?

All hunkered down for the tha shot the bird at best MIGHT see the barrel - but I bet not, as it is MOVEMENT they pickup on.

Just my 2 cnts.

and food for thought
