There are some Glocktalk people in England. Additionally, change the title to "Shipping Gunstock to United Kningdom" or better yet the part of the UK the person is in. Some parts of the UK have different regs than others.
One day, I shall come back. Yes, I shall come back. Until then, there must be no regrets, no tears, no anxieties. Just go forward in all your beliefs and prove to me that I am not mistaken in mine.
