Mil-spec aluminum magazines, and quality Magpul PMAGs.
What more could you ask for? These two -- STANAGs and PMAGs -- are arguably the best 30-round magazines available for the AR platform. They're rugged, reliable, and can be stored loaded for years without spring fatigue.
All 80% lowers we sell are made to fit standard AR-15 magazines. That means all magazines available here are made to fit any lower you buy and fabricate at home.
Both 300 Blackout (supers and subs) and 6.5 Grendel (up to 26 rounds) will fit in any of our available magazines, ensuring they're compatible with any AR-15 kit you buy and assemble that's chambered in these calibers.
