Description
The Odin Works XMR Extended Magazine Release is one of those small upgrades that changes how your AR feels the very first time you run it. The stock button on most lowers is tiny and takes a deliberate reach, especially with gloves on or under any kind of pressure. This paddle is built roughly four times larger than a factory button, giving you a big, easy-to-find target so reloads stay smooth and your support hand never has to leave its spot on the rifle.
What Makes the XMR Mag Release Worth Bolting On
Odin machines this piece from billet 6061 aluminum, so it holds up to years of thumb abuse without wearing out or flexing. The face is contoured and textured for positive depression, which is a fancy way of saying your thumb lands where it should and doesn't slide off when you press. It weighs almost nothing at about a tenth of an ounce, so you're getting a real ergonomic gain with zero meaningful weight penalty. The Flat Dark Earth finish looks sharp on a tan or multicam build and pairs nicely with other FDE furniture.
Fitment and Install on the XMR Extended Release
This drop-in release works with AR-15 lowers and plays nice with plenty of AR-10 style receivers too. It's compatible with KNS anti-walk pins if you run those, and everything you need to swap it in comes in the package. Install is a few-minute job with the included hardware and hex wrench, no gunsmithing required. Worth noting up front: this original XMR is not recommended for use with the Magpul B.A.D. lever, so if you run one of those, look at Odin's newer Gen 3 instead.
Bottom line, if you compete, train hard, or just want faster, more repeatable reloads, this is a cheap and easy win that punches way above its size.

Frequently Asked Questions
Will the Odin Works XMR fit my AR-10?
It's designed primarily for AR-15 lowers but also works with many AR-10 style receivers. Fitment on the AR-10 side can vary by manufacturer, so it's worth confirming your specific lower before ordering. Some larger-format lowers may need an add-on button, so check your receiver's dimensions if you're unsure.
Does this extended magazine release work with a Magpul B.A.D. lever?
No, this original XMR is not recommended for use with the B.A.D. lever. If you run a bolt-action-device style lever, Odin's newer XMR Gen 3 was engineered to play nice with it. For a standard setup without a B.A.D. lever, this one is a great fit.
How hard is it to install the XMR mag release?
It's a genuine drop-in job that most people knock out in a few minutes. You swap your factory button and paddle for the Odin parts using the included screws and hex wrench. No gunsmithing, permanent modification, or special tools beyond what comes in the box.
Is it compatible with KNS anti-walk pins?
Yes, the XMR is built to work with KNS pins, so you can keep your anti-walk setup if you already run them. That's a nice bonus for builders who want to lock down their trigger and hammer pins without giving up the extended release.
