Description
If you're running a bolt-action rifle with AICS-pattern bottom metal, this 10-rounder gives you practical extra capacity without weighing down your setup. It's built on Magpul's proven polymer platform that's been refined through countless field hours.
PMAG 10 AC Polymer Design
Magpul's GEN M3 construction means this magazine can take a hit and keep feeding rounds. The impact and crush-resistant polymer body, stainless steel spring, and self-lubricating follower work together to handle whatever conditions you throw at it. The magazine accepts cartridges up to 2.86 inches in overall length, so you've got room to seat longer bullets if you reload for precision. That's a big deal if you're chasing tighter groups with custom loads.
Handling and Maintenance Features
The flared, removable floorplate makes it easy to grab and load one-handed in the field. It disassembles in seconds without tools, so cleaning and spring replacement are straightforward. A paint-pen dot matrix on the base lets you mark your loads at a glance. Textured surfaces and ribbed design keep the mag locked in your grip, even with cold or wet hands.
Short Action AICS Compatibility
This magazine works with short-action AICS-spec bottom metal on rifles chambered in .308 Winchester, 7mm-08 Remington, 6.5 Creedmoor, .260 Remington, .243 Winchester, and other cartridges built on a 0.470-inch case head. It's compatible with Magpul Hunter stocks that use the Bolt Action Magazine Well. Keep in mind that since AICS bottom metal varies across different manufacturers and chassis, minor fitting may be needed depending on your specific setup.

Frequently Asked Questions
Will the PMAG 10 AC fit my bolt-action rifle?
This magazine fits rifles with short-action AICS-spec bottom metal. Common compatible platforms include Remington 700 short-action, Magpul Hunter stocks with Bolt Action Magazine Well, and many chassis systems. Since aftermarket receivers and bottom metal vary, minor fitting may occasionally be needed. If you have a specific rifle in mind, check with the manufacturer or test fit before committing to multiple magazines.
What calibers does this magazine support?
The PMAG 10 AC is optimized for .308 Winchester and works reliably with other 0.470-inch case head cartridges including 7mm-08 Remington, 6.5 Creedmoor, .260 Remington, and .243 Winchester. It is not compatible with smaller case head cartridges like .223 Remington or .300 AAC Blackout, or with larger short-action magnums.
Can I use this magazine if I reload?
Yes, this is a solid choice for handloaders. It accepts cartridges up to 2.86 inches in overall length, which gives you room to seat bullets longer than factory loads. Many precision reloaders appreciate this mag because it lets them optimize seating depth for accuracy without being constrained by magazine length.
How do I maintain and clean this magazine?
The floorplate removes without tools, making field cleaning simple. Take out the spring and follower, wipe down the internals, and reassemble. The self-lubricating follower means you don't need to add anything special. If the spring ever wears out, it's an easy swap. Magpul designed these mags to be user-serviceable in the field.
