Soviet Underwater Firearms 10 years ago
Re: the last gun in the article:
The rifle’s effective firing range underwater is about 25 meters at a depth of 30 meters and 18 meters at a depth of 20 meters, according to Russia Today.
Earlier in the article they associate an increase in depth with a lessened range, but with this one it's the reverse? Is that a typo or a nuance of the technology?
