I am thinking of putting some black silicone in some holes that were left by barrel sights in a barrel of mine...? Anyone feel the need to tell me this is a stupid idea? I'm thinking of doing it because I dint want the hole to fill up with junk and if need be down the road I should be able to get the silicone out of the hole fairly easily. The threads in the hole are stripped for those wondering why I'm not putting a flush screw in the hole.
