How to Use Your Military Surplus French ARF-A (Based on the Polish MP-5) Gas Mask

THIS IS A FRENCH ARF-A, not an MP5. Hi folks, thanks for the correction on the mask model. This was sold to me by the vendor as an MP5 and I'm just getting started in my milsurp collection so I was not informed enough to call them on it. Appreciate all the good info added in the comments! Don't need any further corrections on the mask model thanks, we got the title of the video changed and everything. We're all set.
