Description
Your mag release is one of those parts you touch on every single reload, yet most factory rifles ship with the roughest, cheapest one in the parts kit. The Fortis Billet Mag Catch & Button Combo fixes that for less than the cost of a range trip. It's a matched two-piece upgrade, a billet 6061-T6 aluminum button paired with a serrated stainless catch and rod, so the whole assembly works together instead of you mixing and matching random components.
What the Fortis Mag Catch & Button Combo Does Differently
The front of the catch and release lever gets aggressive serrations, which is the part your finger actually feels. That texture gives you positive, no-look mag drops when your eyes are downrange and your gloves are on. The button keeps the same low profile as a mil-spec unit on purpose, so you get a cleaner press without accidentally over-throwing the catch and hanging up your reload. It's a small detail that makes a real difference once you've run a few mags through it.
Built From the Right Materials
Fortis machines the button from a solid piece of 6061-T6 aircraft-grade aluminum with an anodized finish, while the catch and rod are 303 stainless steel for durability where the wear happens. The catch also runs full-length threaded internals, so it threads on securely and holds up to hard use. The whole assembly is genuinely lightweight, which is a nice bonus if you're chasing ounces on a build.
Dropping the Fortis Combo Into Your Lower
Installation is about as simple as AR upgrades get. It's a direct drop-in swap for the mag catch and button in a standard mil-spec lower, no permanent modifications and no specialty tools beyond what you'd already have on the bench. Most folks have it done in a couple of minutes. If you're building a lower from scratch or refreshing an older rifle, this is one of the easiest quality-of-life improvements you can bolt on.

Frequently Asked Questions
Will the Fortis mag catch and button combo fit my rifle?
It's designed as a direct replacement for the magazine catch and button in a standard mil-spec AR-15 lower receiver, and it also works with AR-308/AR-10 pattern lowers that use mil-spec dimensions. If your rifle takes a standard mag catch, this drops right in. There are no proprietary cuts or oddball measurements to worry about.
Is the Fortis mag catch and button combo hard to install?
Not at all. It swaps in the same way as any mil-spec mag catch, so most people have it done in a couple of minutes with basic tools. You'll depress the catch, back the button off, and thread the new assembly in to your preferred engagement, then set it flush and test with an empty mag.
What's the difference between this and a standard mil-spec mag release?
The Fortis combo keeps the same low profile as mil-spec so you don't over-throw the catch, but it adds aggressive serrations on the release lever for positive no-look mag drops. The materials are also a step up, with a billet aluminum button and stainless catch and rod for durability. It's a cleaner, more precise feel every time you touch it.
Does the Fortis mag catch and button combo come as a complete set?
Yes. This is the full combo, so you get the machined button, the magazine catch, the catch rod, and the spring in one package. Everything you need to replace the factory unit is in the box.
