The way I see it, the mag might be legal in it's own right, but centerfire semi-auto rifles are limited to 5 regardless which mag it uses. In the case of pistol carbines they fall in between... when it runs rifle mags it's a semi-auto rifle, when it runs pistol mags it's a long barelled handgun. The mag can maybe made legal but it would not be legal to use in the AR-15. My 0.02$
