As more of today's shooters build or buy guns equipped with chassis systems designed to accept detachable box magazines, they're encountering some issues related to feeding, particularly as it relates to ACIS-pattern stocks and chassis mated with .378" case-head-diameter cartridges like the 5.56 NATO/.223 Rem. To address these issues and provide an affordable option for precision shooters using these calibers, Magpul rolled out its unique PMAG 10 designed for use with 5.56 NATO-sized cartridges and those based on the 5.56 NATO.

The unique shape of the Magpul PMAG 10 5.56 AC has to do with this detachable box-magazine compatibility issue. The top portion of the magazine body is sized to fit standard AICS-pattern magazine wells that were initially designed with short-action rifle cartridges like the .308 Win. in mind, most of which feature a .473" case-head diameter. The magazine also features an offset feed-lip geometry, which helps to solve the bolt-face issue encountered with other AICS-pattern magazines designed for use with 5.56 NATO-based cartridges.

Each Magpul PMAG 10 5.56 AC is constructed using the company's GEN M3 technology, which features a self-lubricating follower, a stainless-steel magazine spring and a constant-curve geometry incorporated into the magazine body that provides seamless feeding and function. Like all of the company's magazines, this PMAG 10 5.56 AC is constructed with polymer, which is designed to provide crush- and impact-resistant protection. One of the other features found in the magazine is the inclusion of a paint-pen dot matrix, which allows users to keep track of multiple magazines for competition and range use.

Magpul's PMAG 10 5.56 AC holds up to 10 rounds of 5.56 NATO or other cartridges with a .378" case head, and the magazine can accept cartridges with a maximum overall length of 2.39". The PMAG 10 5.56 AC measures 5.01" high, 3.05" long and .97" wide. Total weight of the magazine, unloaded, is 2.71 oz. Suggested retail pricing on the PMAG 10 5.56 AC is $39.95.
