Hello, and welcome to the forum. The absence of replies suggests your question is a tricky one; and I have no answer for you, either. I would suggest going to Bud's Gun Shop (
www.budsgunshop.com). At the top of their home page there is a Customer Q and A link for you to ask your question. Buds may have the ability to ship to S. Korea or, maybe, they can offer a referral to you.
Good luck.
