I bought some of the camo tape and made my own,it peels right off with no problem. I only use it from the breach to the end of the choke because the butt is covered up. I think as has been said if you keep still thats what really matters.
I must admit I was glad I used the camo tape because the two birds I had a chance at came in real close to me at 10' and 8 feet,so the extra camo did not hurt a bit.
