Aero Precision Extended Magazine Catch Button For .308

Product Description

The Aero Precision Extended Magazine Catch Button For .308 is a replacement magazine release component designed for AR-10 pattern rifles chambered in .308 Winchester and 7.62x51mm NATO. This extended button offers a larger contact surface than standard magazine catches, making it easier to activate the magazine release without adjusting your firing grip.

The extended profile is especially useful for shooters wearing gloves, those with larger hands, or anyone who prefers faster magazine changes during competition or training. It installs using the existing magazine catch assembly in your AR-10 lower receiver.

Because this component is caliber-specific to .308 AR-10 builds, it is not compatible with standard AR-15 lowers. The geometry is tailored to work with the larger magazine well and thicker lower receiver found on .308 platforms.

AR-10 Magazine Catch Compatibility

This magazine catch button fits AR-10 and .308 pattern lower receivers, including those from Aero Precision, DPMS, and other manufacturers following DPMS-pattern dimensions. It does not fit AR-15 lowers due to differences in magazine well size and catch geometry.

The extended button replaces only the button portion of your magazine catch assembly. The paddle, spring, and threaded catch body remain in place. If you are building a new lower or replacing the entire magazine catch, you will need the complete assembly rather than just the button.

Why Choose an Extended Magazine Catch

A standard magazine catch button can be difficult to reach without breaking your grip, especially if you have shorter fingers or are wearing heavy gloves. The extended button projects further from the lower receiver, reducing the distance your trigger finger must travel to drop a magazine.

This modification is popular among competitive shooters who need every advantage in reload speed. It also helps newer shooters develop consistent magazine change mechanics without fumbling. The larger surface area means less precise finger placement is required to activate the release.

Installation and Fit Considerations

Installing this button requires disassembling your existing magazine catch. You will need a punch or similar tool to depress the catch from the right side of the receiver while unscrewing the threaded portion from the left. Once separated, the old button slides off and the new extended button slides on in its place.

Our gunsmith can walk you through the process or handle the installation if you prefer.

Frequently Asked Questions

Q: Does the Aero Precision extended magazine catch work with AR-15 rifles?

A: No, this extended magazine catch button is designed specifically for .308 AR-10 pattern rifles and will not fit AR-15 lowers. The AR-10 magazine well and catch dimensions are larger than those on an AR-15 platform, so the components are not interchangeable.

Q: Can I install this magazine catch button myself?

A: Yes, most shooters can install this button with basic tools including a punch and possibly a screwdriver or magazine catch tool. You will need to remove the existing magazine catch assembly, swap the button, and reassemble. If you prefer professional installation, Western Sport offers gunsmithing services.

Q: Will this extended button work with all AR-10 lower receivers?

A: This button is designed for AR-10 and DPMS-pattern .308 receivers. Most AR-10 lowers follow similar specifications, but variations exist. Send us a message if you need to confirm compatibility with your specific lower receiver before ordering.

Q: How much further does the extended button stick out compared to a standard catch?

A: The exact extension dimension is not provided. The button is noticeably larger than a standard magazine catch, making it easier to reach without adjusting your grip.

Q: Is the Aero Precision extended magazine catch button ambidextrous?

A: No, this is a standard right-side magazine catch button. It installs on the left side of the receiver and is activated by the shooter’s right-hand trigger finger. For ambidextrous or left-handed operation, you would need a complete ambidextrous magazine catch assembly.

Q: Does this button require any permanent modification to my lower receiver?

A: No, the extended magazine catch button installs using the existing magazine catch hole in your AR-10 lower receiver. It is a drop-in replacement for the button portion of your magazine catch assembly and can be swapped back to a standard button at any time.
