Alright, here is the update, surprisingly he gave me a full refund this morning. I would take your advice and try to buy optics from USA.
Do I need to pay taxes for buying optics from USA? If the answer is yes, then how am I supposed to pay it?
Thank you, I just emailed him that I changed my idea, and ask for a full refund. I barely dodged him this time.
I have to admit I am a lucky person. Just asking, where did you guys bought your optics? Is there any store you guys would like to recommend to me?
Thank you for replying my message, Xtreme Tactical emailed me this night said his contact in USA couldn't found available stock, and he suggested for a refund, so I decied to take my money back. I also ordered a holosun hm3x magnifier with the sig red dot and light. He said the magnifier is coming, should I keep the magnifier? I brought it during black Friday discount sales.
