Description
The factory magazine release on a stock 10/22 gets the job done, but pinching that little latch under the rifle with your thumb and finger slows you down at the range. This genuine Ruger extended release replaces it with a bigger, contoured surface you can work with a single finger, which turns fumbling reloads into a quick, one-motion swap. It's molded from the same heat-stabilized, glass-filled polymer Ruger uses for its trigger housings, so it holds up to real use and blends in like it came on the gun from the factory.
Why the 10/22 Extended Mag Release Earns Its Spot
What sets this one apart from the aftermarket crowd is the balance. It's long enough to reach easily with your trigger finger, but it isn't so oversized that it hangs up on gear or drops your mag by accident. The push pockets are fully ambidextrous, so lefties and righties both get the same clean access, and the flush-fit contour tucks right up against the trigger guard. Folks who run BX-1, BX-25, and the standard Ruger rotary mags consistently find their changes faster, smoother, and more controlled.
Fitting the 10/22 Extended Magazine Release
Installation is a true drop-in job with no modification and no gunsmith required. You pop out the old latch and set this one in its place, which most people knock out in a couple of minutes with a quick reference video if it's their first time. Because it's a Ruger OEM part rather than a third-party knockoff, the fit is dialed in and there's no rattle.
This release fits all 10/22 autoloading rifle models along with the 22 Charger pistol, so whether you're building out a range plinker, a squirrel gun, or a Charger setup, it's a low-cost upgrade that pays off every time you swap a magazine. Made in the USA.

Frequently Asked Questions
Will this extended magazine release fit my 10/22 Takedown or 22 Charger?
Yes. This release is compatible with all Ruger 10/22 autoloading rifle models, including the Takedown, as well as the 22 Charger pistol. It works with the standard Ruger rotary mags plus BX-1 and BX-25 magazines.
Is the Ruger 10/22 extended magazine release hard to install?
Not at all. It's a true drop-in part that replaces the factory latch with no modification and no gunsmithing needed. Most people swap it in a couple of minutes, and a quick reference video makes it even easier if it's your first time.
Is this a genuine Ruger part or an aftermarket copy?
This is a genuine Ruger OEM factory accessory, part number 90598. It's molded from the same heat-stabilized, glass-filled polymer Ruger uses for its trigger housings, so the fit is precise and there's no rattle.
Is this release too long, will my magazine drop by accident?
This one is designed with a balanced length that reaches easily with a single finger without being so oversized it snags on gear or drops the mag on its own. The flush-fit contour keeps it tucked against the trigger guard, and users regularly note it stays out of the way during normal handling.
