Better M16 Rifle, M4/M4A1 Carbine Magazine AvailablePosted: 2012/26/01
A better magazine has been available for the M16 rifle and M4/M4A1 carbine for a couple of years now. The new 30-round magazine, NSN 1005-01-561-7200, has a redesigned follower and a stronger spring that should provide greater reliability and fewer malfunctions. You can ID the new magazine by its tan follower. The old magazine, NSN 1005-00-921-5004, is being phased out, but you should continue to use them until they need replacing.
