This replacement magazine is a factory original from Magpul Industries. Designed to fit the AR-15 rifle.Built to hold (30) rounds of ammunition. Will only hold 300 AAC Blackout rounds. Constructed of next-generation impact and crush resistant polymer. This magazine also comes equipped with a hi-tensile compression steel spring to assure this magazine has minimal to no friction, and smooth feeding responses.The GEN M3 Window incorporates new material technology and manufacturing processes for enhanced strength, durability, and reliability to exceed rigorous military performance specifications.In addition, a redesigned bolt catch notch in the rear of the magazine provides increased bolt catch clearance, while an over-travel stop on the spine helps ensure the magazine will not over-insert on compatible weapons. Low profile ribs and new aggressive front and rear texture gives positive control of the GEN M3 in all environments, and a paint pen dot matrix has been added to the bottom panel of the body to allow easy marking by the end user for identification.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.Dust cover sold separately
