Right, but there is a difference between a detachable box magazine and a big, chunky, sharp-edged detachable box magazine.
My P-Scout has a detachable box magazine. That doesn't mean it has a monstrosity of a magazine on it.
I'm familiar with what a scout rifle is......I'm asking what the attraction to a large magazine like the Ruger GSR is. I don't know if it's just a poor feature, or if there is an actual reason/advantage to it.
