Magpul's New 5.56 AICS Mag is a Boon for .223/5.56 Long Range Trainers

Precision shooters that like to save cash by training with .223/5.56 in place of their pricey 6mm cartridges, but there aren't many choices for reliable AICS pattern mags in that caliber. The PMAG 10 5.56 AC offers up a highly engineered solution to the problem of reliably feeding the 223 Rem cartridge and its notoriously stingy bolt face presentation.
