This computer simulation depicts the operation of the Army’s Improved Magaine.
The Army has begun fielding the new 5.56mm 30 round Improved Magazine that delivers a significant increase in reliability for the battle-tested M16 and M4 weapons systems. Bolstering the already high reliability ratings of the M16/M4 systems, the Improved Magazine effectively reduces the risk of magazine-related stoppages by more than 50 percent compared to the older magazine variants. Identified by a tan-colored follower, over 500,000 of the improved magazines have been fielded to units in Iraq, Afghanistan and in the U.S.
Pretty big oversight when the Army forgets the extraction of the casing in their video. Even if they got the extraction right, the entire video would still be 100% useless.
