Nehemiah Bianchi's Review of Magpul Industries PMAG GEN M3 AR-15 .300 Blackout 20 Round Rifle Magazine

It's magpul, same quality and reliability but optimized for .300 blackout. There's not much more to say about it, other than if you want/need a .300 blackout specific 20 rounder then look no further.
