With all these fires going around and the potential of house fires a quick question about gas masks.
Is the RD40 40mm thread EN-148-1 the same as the STANAG 4155 Nato thread?
Would a draeger rd 40 filter fit a MP5 Gas mask ? Or a military nbc filter fit a draeger x-plore-6300?
Edit: Just want to know if the civilian and mil spec threading is identical.
I’ll he cross posting the question. Last resort would be reddit 🙈
Why not try ChatGPT, and then try to google ChatGPT’s answer? That’s what I do these days. Google is hard to search these days and ChatGPT alone cannot be trusted as a source of truth. Together, you can get a reasonable idea.
Or try calling an army surplus store?
