No idea why Magpul called their stock a “Hunter” stock - it ain’t a hunting stock. But... It absolutely makes sense for Ruger to name their rifle USING that Magpul stock the American + “whatever Magpul calls their stock.” Can’t call it the Ruger American Magpul, ‘cuz that lines too closely beside the similar Remington option.
Regardless of taxonomy or etymology, the Ruger American Hunter is made to compete with the 700 Magpul, and the Ruger is probably a better option than the 700 at this point. So sure, why not. If you need an inexpensive, mid-weight barrel, DMB, bench/prone/improvised support fired, threaded muzzle rifle, then the Ruger American Hunter and Rem 700 Magpul might be good options.
Not many hunters need those parameters. But the RAR base model does meet the average hunter’s needs already.
