What type of adhesive is commonly used to attach the Velcro pads on a bbl for a shield? At some point ( when it won't shoot 1/4 moa) I will remove the pads from the blued bbl and I don't want to damage the bluing. I did a search and found a post saying high temp rtv will hold these on a hot bbl , but thought perhaps someone here could give me some advice on what to, and what not to use in my case.
