The TPS Arms AR-15 Mag Catch Assembly (Model AR-1031) is a precision-manufactured replacement or upgrade component for AR-pattern rifles. If your rifle's mag catch is worn, damaged, or you're building a new upper or lower, this black assembly handles the straightforward job of keeping your magazine seated and ready. TPS Arms focuses on durability and tight tolerances—the kind of no-nonsense parts that let you focus on shooting instead of worrying about whether your gear will hold up.
Whether you're assembling a rifle from scratch, swapping parts on an existing build, or maintaining a rifle that's seen hard use, a quality mag catch assembly is a small detail that matters. It's the interface between your magazine and receiver, and loose or damaged catches lead to feeding issues and frustration. TPS Arms' approach here is straightforward: solid construction and precision fit so it does its job reliably, year after year.
This is a common maintenance and upgrade item for AR builders and owners who demand parts that work without drama. Stock up, rebuild, or upgrade—this assembly is ready to go into your build.
