Description
The mag catch is one of those small parts most people never think about until they're staring at a lower parts kit, but it's what holds your magazine locked in place until you want it gone. Fortis machines this one from a solid piece of 6061-T6 aircraft-grade aluminum instead of the stamped part you'd normally get, then finishes it in an OD Green hardcoat anodize that plays nice with the rest of a earth-tone or green build. The catch rod is 303 stainless steel for extra durability where it counts. This listing is the mag catch only, so it's the piece that swaps into your existing setup rather than a full button-and-catch combo.
Where the Fortis Billet Mag Catch Fits In
This is a direct replacement for the standard AR-15 magazine catch. It threads into your existing mag release button and works with standard AR-pattern magazines, so you keep the same function and the same manual of arms. If you're assembling a lower from parts, or you want to color-match a catch that got left out of a two-tone build, this is the piece that fills that gap. Installation is quick and uses the same process as a mil-spec catch.
Why Go Billet Over Mil-Spec
Billed construction and a proper hardcoat anodize hold up better against wear and the elements than a stamped and phosphated part. At roughly 5.5 grams with the rod, it stays feathery light, which matters if you're chasing every ounce on a lightweight build. It's a modest upgrade in the grand scheme of a rifle, but it's the kind of detail that makes a hand-built lower feel finished.
Made in the USA
Fortis builds these stateside, and the fit and finish reflect it. The threading is clean, the tolerances are tight, and it goes together without fuss. For anyone who cares about the small parts matching the quality of the big ones, this is an easy call.

Frequently Asked Questions
Does the Fortis mag catch come with the magazine release button?
No, this listing is the mag catch only. It's the latch that engages the magazine, along with its 303 stainless catch rod, and it threads into your existing mag release button. If you want the matching billet button too, Fortis sells a separate catch-and-button combo.
Will this Fortis billet mag catch work with my standard AR-15 lower?
Yes. It's a direct replacement for the mil-spec magazine catch and works with standard AR-pattern magazines and release buttons. It installs the same way the factory catch does, so there's no permanent modification to your lower.
Is the OD Green finish anodized or coated?
The aluminum catch gets a hardcoat anodize in Olive Drab Green, which is durable and holds up well to wear and the elements. It's a nice match for earth-tone and green builds where you don't want a black part sticking out.
How hard is it to install the Fortis mag catch?
It's a straightforward swap that uses the same process as a standard mil-spec catch, so most folks can knock it out in a few minutes. You'll compress and thread it through the lower the same way the factory part goes in. No special tools beyond what you'd already use for basic AR lower assembly.
