Thanks to Miles for sharing this photo. Does anyone know who makes this rather potent looking AR mag? It is rather long and curves a bit to the right lol Joking aside would this be a 100 rd magazine? I am curious about the logistics of this magazine. I don’t see how they carry these huge things on them. You can just stick them in a pocket or a pouch. Are they stowed on the side of a pack? Why not just use a drum or the SureFire quad stack magazines?
