Description

The factory magazine release on most ARs is a tiny little nub, and if you've got shorter fingers or you're running gloves, reaching it means shifting your whole hand. The Odin Works XMR Extended Magazine Release fixes that. It bolts onto your standard mag catch post and gives you a paddle that's roughly four times the surface area of a mil-spec button, so a quick tap drops your mag while your grip stays put.

What Sets the XMR Apart

This one is machined from billet 6061 aluminum and finished in a matte black hard-coat anodize, so it holds up to real use without adding any real weight. The whole unit, paddle, button, and screws included, tips the scale at about 0.15 ounces. The face is contoured with serrations that give your finger positive grip and reduce slip, which matters when your hands are sweaty or cold. It takes a deliberate press to release, so you get the extra reach without worrying about bumping a mag loose by accident.

Fitting the XMR to Your Build

Installation is genuinely a few-minute job. You pull your existing mag catch button, thread this one on in its place, and you're done. No special tools, no fitting. It works on both AR-15 and AR-10 pattern lowers, which makes it an easy pick whether you're upgrading a 5.56 carbine or a .308 rifle. Folks running Aero M5 and similar wide .308 receivers sometimes pair it with an extended-shaft catch for the best reach.

A note on compatibility worth knowing up front: the original XMR plays nice with many KNS anti-rotation pins, though clearance can vary by pin generation, so check your setup if you're running anti-walk pins. It's also not the version to grab if you run a Magpul B.A.D. Lever. If BAD Lever compatibility is a must, the XMR 3 is the one built for that. For most standard mil-spec lowers, this flagship XMR remains one of the most popular reload upgrades out there for good reason.

Frequently Asked Questions

How hard is the Odin Works XMR to install?

It's a drop-in swap that takes just a few minutes. You remove your existing mag catch button and thread the XMR on in its place using the included hardware. No special tools or gunsmithing needed, and everything you need comes in the package.

Will the XMR mag release work on my AR-10 or .308 lower?

Yes, it's designed to fit both AR-15 and AR-10 pattern lowers. On wider .308 receivers like the Aero M5, some builders pair it with an extended-shaft mag catch to dial in the reach, so it's worth checking how your particular lower is set up.

Does the Odin Works XMR clear KNS anti-rotation pins?

It's built to work with many KNS anti-rotation pins, and plenty of users report zero interference. That said, clearance can vary depending on the pin generation and other lower components, so it's smart to verify with your exact setup. If you want guaranteed BAD Lever compatibility, look at the XMR 3 instead.

Is there a risk of dropping a magazine by accident with a bigger button?

Not really. While the paddle is roughly four times the size of a mil-spec button, it still takes a deliberate press to release the mag. The extra surface area just makes it easier to reach without shifting your grip, not easier to bump loose.
