Made in the USA, the PMAG 10 5.56 AC is a polymer 5.56x45 NATO 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.
