The Odin Works XMR Extended Mag Release is a drop-in replacement magazine release for AR-15 pattern lower receivers, designed to provide a larger activation surface than factory magazine releases. The black finish matches most standard lower receivers.
An extended mag release reduces finger travel and increases the surface area you press during reloads. That matters most when you wear gloves, shoot with support-hand manipulation, or simply want to shave fractions of a second off magazine changes.
The XMR installs in place of your factory magazine release using the same detent and spring. It works with standard and oversized magazine release buttons.

How the Odin Works XMR Fits Your Build
The Odin Works XMR extended mag release installs into any mil-spec AR-15 lower receiver. It replaces the factory magazine release that threads into the right side of your receiver.
You will reuse your existing magazine release spring and detent. The XMR threads into the same hole as the factory part, so no modification to your lower is required.
This component is classified as a lower part and does not require an FFL transfer when purchased separately.

What to Know Before You Buy
An extended magazine release increases the chance of accidentally dropping a magazine if you rest the rifle against barricades or grab the lower near the magazine well. Some competition shooters accept that trade-off for faster reloads under the clock.
If you run a very short or aggressive grip angle, test-fit the XMR to confirm your trigger finger does not contact the extended surface during normal firing. Most shooters find the XMR profile adds reach without interference.

Frequently Asked Questions
Q: Does the Odin Works XMR extended mag release fit all AR-15 lowers?
A: The Odin Works XMR fits any mil-spec AR-15 lower receiver that accepts a standard threaded magazine release. It replaces the factory magazine release and uses the same detent and spring already in your lower.
Q: Is the Odin Works XMR a firearm part that requires an FFL transfer?
A: No, the Odin Works XMR is classified as a lower part accessory and is not a firearm. You do not need an FFL transfer to purchase this component separately.
Q: How does the Odin Works XMR compare to a standard magazine release?
A: The Odin Works XMR provides a larger activation surface than factory magazine releases, which reduces finger travel and makes magazine drops easier when wearing gloves or shooting with your support hand. The trade-off is a slightly higher risk of accidental magazine release if the rifle contacts objects near the magazine well.
Q: Can I install the Odin Works XMR extended mag release myself?
A: Most builders install the Odin Works XMR at home using a standard magazine release tool or screwdriver and needle-nose pliers. The part threads into the same hole as your factory magazine release and reuses the existing spring and detent. If you prefer professional installation, Western Sport offers gunsmithing services.
