For some reason, I feel obligated to warn you:
This site is generally not the place to post you airsoft questions, although there are members here who participate and they may reach out to you. Generally speaking, it is best to spend your first few months (or years) here reading through the various topics and enlightening yourself on not only the format, but the content before posting; unless the topic is very specific and you can provide the relevant parameters.
"Plate carriers and armor" is probably one of the most discussed topics on this site, so there is a ton of info available to you at your fingertips, should you chose to look. You aren't likely to get many responses, based on your initial post. Many people here wear armor for a living, so any response you get (or lack thereof) will be filtered through that lens. I see that you joined our ranks today. I hope you made your post in the new member thread (per you initial email on instructions) before you shot this RFI out. Good luck.
