Which magazine do people think would be better for my DPMS 5.56 Sportical rifle, the DPMS 30 round teflon coated magazines or the 30 round Colt AR mags. I see the COlts are more expensive and maybe better quality, but I don't know. However, would the DPMS mags be better suited for the DPMS gun, since they are same brand, and I would think, made for the DPMS guns?
