For AR-15 and pistol-caliber carbine enthusiasts living in capacity-restricted states, Mean Arms developed its AR-9 Endomags, which are limited to 10 rounds and designed for use in traditional AR-15 magazine wells. Thanks to this design, these enthusiasts can top their standard AR-15 lower with a 9mm upper receiver and plink away or join the fast-growing PCC clubs across the country. Built using either a Gen 2 or Gen 3 Magpul PMAG, the Mean Arms AR-9 Endomag fits all standard AR-15 magazine wells and is compliant as an unmodifiable, 10-round magazine due to the fixed baseplate. The magazine is designed for use with Glock- or Colt-pattern bolt-carrier groups. The product functions with all standard 9mm ammunition and will fit with all accessories designed for use with Magpul PMAGs.
