Update : Edited this post, apparently I made a mistake, its NS-30, not NS-30A, sorry guys.
It was produced by Korean company, but looks like they're now producing military stuff only.
Google results don't show many details, only found a brochure of it's specification attached below.
Any comments or words about this SA will be appreciated.
