The Magpul PMAG Gen M2 MOE didn't become the default AR magazine by accident. Thirty-round capacity, impact-resistant polymer construction, and consistent feed reliability across a wide range of AR-15 and M4-pattern platforms chambered in .223 Rem / 5.56 NATO. These have been run hard by everyone from competition shooters to military units for good reason. Black, 30-round, five-pack — stock up while they're here.
