Smith & Wesson M&P10 Magazine 308 Winchester 5-Round

This Smith & Wesson metal magazine is constructed of steel. This replacement magazine is a factory original from Smith & Wesson. Factory replacement parts are manufactured to the exact same specifications and tolerances and use the same manufacturing materials as the original parts which guarantees excellent fit and reliable operation. Keeping a few extra factory magazines around is never a bad idea; extra magazines save loading time at the range and also serve as a backup for those days when you simply cannot remember where you put your primary magazine.
