AICS PMAG: the PMAG 10 5.56 AC for Bolt Guns


The PMAG 10 5.56 AC (as in AICS style) magazine has been presented by Magpul Industries as a solution to feeding small cartridge case diameters in rifles with AICS-pattern metal mags. Such calibers in that style of magazine can be problematic.

We have a handy video that explains. It’s hosted by the spring-fed mag cousin of the TVA’s Miss Minutes and should answer any of your basic questions.

Magpul explains the difficulties in more detail thusly:

“The problem with designing a detachable mag for 223 Remington in 5.56 x 45 bolt action rifles with AICS pattern bottom metal is that with small cartridge case diameters and standard bold faces, there is not a lot of room to get the geometry right.

In a conventional magazine design, this can lead to bolt over stoppages, overall length sensitivities, follow or dive, and a generally less than great experience than when feeding larger cartridges.

Magpul’s PMAG 10 5.56 AC solves this little dilemma with a polymer magazine designed for short action AICS pattern bottom metal in cartridges built on a .378 case head, and an overall length of 2.39 in. We based our solution on an offset feed lip geometry that maximizes bolt face engagement and resists follow or dive, guaranteeing reliable feeding in solving pesky bolt face overlap issues.

The PMAG 10 5.56 AC shares many features with its larger siblings in the PMAG line, with the same DNA that makes our GEN M3 PMAG  the most reliable, and most durable magazines in the world…with a unique form factor so you won’t easily mix them up with your other AICS pattern mags.

Compatible with all short action AICS pattern bottom metal, including our own bolt action magwells for the hunter family of stocks. The PMAG 10 5.56 AC sets a new standard for bolt action standard technology.”

PMAG 10 5.56 AC – AICS Short Action

This is the formal description provided by Richard Fitzpatrick‘s crew.

The PMAG 10 5.56 AC is a polymer 5.56×45 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. 

Designed with many of the same qualities that make our PMAGS the most reliable and durable in the world, the PMAG 10 5.56 AC features GEN M3 technology, including a self-lubricating follower, a stainless-steel spring, and constant-curve internal geometry for smooth feeding. It also 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.

Like our other Magpul bolt action magazines, it features a paint-pen dot matrix for visual identification and a flared base plate for positive control and ease of retrieval. Designed from the ground up to solve the challenges of feeding 5.56/.223, the PMAG 10 5.56 AC sets the standard for bolt action magazine technology.

Made in the USA.
