Magpul PMAG AC AICS Short Action .308 Win Polymer Magazine - Black

The Magpul PMAG AC AICS short action .308 Win polymer magazine delivers reliable, high-capacity feeding for bolt-action rifles built on short-action AICS-pattern bottom metal. Whether you're running a Remington 700, Ruger American, or any other modern chassis system that accepts AICS magazines, this is the go-to mag for hunters and long-range shooters who demand dependable ammunition storage without the weight or cost of steel. Magpul's GEN M3 technology and field-proven design make it a workhorse in the field or at the bench.

Built from tough, impact-resistant polymer, the PMAG AC features a flared floorplate that makes magazine changes smooth and retrieval from a mag carrier effortless. The self-lubricating follower keeps rounds feeding cleanly across calibers built on the standard .470-inch case head—that includes not just .308 Winchester, but also 7mm-08, 6.5 Creedmoor, .260 Remington, and .243 Winchester. Magpul included a long-life stainless steel spring and designed the follower with a modifiable leg, so if you need that extra round of capacity, you can clip it to adjust on the fly. The removable floorplate also makes field stripping and maintenance straightforward, no tools required.

Magpul's paint-pen dot matrix on the body lets you mark and color-code your magazines for different load-outs or hunting seasons—practical if you're juggling multiple rifles or ammunition weights. Made in the USA, this magazine represents the balance of proven reliability, thoughtful design, and real-world usability that shooters expect from Magpul. Available in both 5- and 10-round capacities to match your platform and hunting regulations.

Frequently Asked Questions

What bolt-action rifles work with the PMAG AC AICS magazine?

This magazine is designed for short-action AICS-pattern bottom metal, which includes Remington 700 platforms, Ruger American rifles, and modern chassis systems like the Accuracy International Hunter 700 Stock. Because of the variety of aftermarket receivers and chassis, minor fitting may occasionally be required. The Sig Cross also accepts these magazines, though it ships with a Sig-optimized variant.

Which calibers can I use in this .308 magazine?

The PMAG AC works reliably with .308 Winchester and other cartridges built on a standard .470-inch case head, including 7mm-08 Remington, 6.5 Creedmoor, .260 Remington, and .243 Winchester. It is not compatible with smaller case-head calibers (.223 Remington, .300 AAC Blackout) or larger short-action magnums, and it does not work with Accuracy International AE rifles or semi-auto SR25/M110 pattern magazines.

Can I increase the capacity of the 5-round magazine?

Yes. The follower includes a modifiable leg that you can clip to increase capacity by one extra round, giving you flexibility to adapt the magazine to different hunting seasons or range sessions.

Is this magazine easy to take apart for cleaning?

Absolutely. The flared floorplate is removable and requires no tools to disassemble, making routine maintenance and cleaning quick and straightforward in the field or at home.
