White Label Armory WLA-LOW-1010-01 AR15 Magazine Catch Kit, Black Steel

Description

The magazine catch is one of those small AR15 parts that nobody thinks about until it stops working right. White Label Armory built this kit to Mil-Spec dimensions so it fits standard AR15 lowers without any fuss, whether you're finishing a fresh build or swapping out a worn part that's started letting mags wobble or drop early. You get the three pieces that make the whole system tick: the catch, the spring, and the release button.

What Goes Into the WLA-LOW-1010-01 Mag Catch Kit

The catch itself is steel with a phosphate finish, which is exactly what you want for a part that takes constant pressure and repeated engagement. The release button is machined from 6061-T6 aluminum and anodized black to match the rest of your lower, and the spring keeps steady tension so the button springs back every time you thumb it. All of it is made in the USA and cut to Mil-Spec tolerances, so there's no fitment guesswork or hand-filing to get things seated.

Why This Magazine Catch Kit Earns Its Spot

A sloppy mag catch shows up at the worst times, usually on the range mid-reload. Going with a properly machined and heat-treated part means your magazines lock in solid and release clean, which matters whether you're running steady bench sessions or faster drills. Compared to the cheaper imported catches floating around, this one holds its dimensions and holds up over a lot of mag changes.

Installing the WLA AR15 Mag Catch

Swapping a mag catch is a straightforward job for anyone comfortable working on their lower. The catch drops through the receiver, the spring seats in the button, and you thread it together by pressing the button in and turning the catch until it's flush. No special tools beyond a punch and a steady hand. If you're building a lower from scratch, this pairs naturally with the rest of your lower parts kit components.
