•For Use with Aftermarket AR-15 Magazines

Last year Mossberg rocked the rifle world with the introduction of its MVP rifle. In case you don't know, the MVP is a bolt-rifle in .223 Rem. that feeds from a detachable box magazine. The kicker is it's not just any magazine; the MVP uses AR 15 magazines. Whether five, 10, 20 or 30 rounders does not matter. If you have a magazine that will work in an AR 15, it will work in a Mossberg MVP.
