How old is that article? It says,
"Browning has done something that was so obvious that it’s really quite remarkable that it hadn’t been done before."
That is an odd statement considering that _Browning_ did it before. As jackmountain said, they called it the Acera.
I find straight-pull bolt guns very interesting. If one finds semi-autos unreliable, or potentially unreliable, or scary because they _might_ be unreliable, then this addresses that concern in a proven design that's faster, easier, and smoother to operate than a turnbolt action. I imagine that not everyone would be interested, just as not everyone is interested in every particular rifle on the market.
The difference is that the Acera operated much like any other straight pull: pull back, push forward. On the Maral you don't have to push forward. The bolt is driven closed by springs, so you pull back and let go.
It seems very much built for jurisdictions where self-loaders are restricted, but people want a fast repeater, and one which holds a fair few rounds of something powerful. 10+1 rounds of 9.3x62 should be just the ticket for knocking down a mob of running pigs, I think.
