The PMAG 10 5.56 AC is a polymer 5.56x45 NATO (.223 Remington) magazine designed for short-action Accuracy International Chassis Systems (AICS)-pattern bottom metal, including the Bolt Action Magazine Well for the Magpul Hunter family of stocks.
It features GEN M3 technology, including a self-lubricating follower, a stainless-steel spring, and constant-curve internal geometry for smooth feeding of 10 rounds.
Designed from the ground up to solve the challenges of feeding 5.56/.223, it incorporates offset feed lip geometry that maximizes bolt-face engagement, guaranteeing reliable feeding and solving the bolt-face issue common to other AICS-pattern magazines for 5.56-based cartridges.
