Mag Catches

AR15 Magazine Catch Buttons for AR-15 Lower Builds

The magazine catch is a small but essential part of the AR-15 lower receiver. It secures the magazine in place and releases it when you press the mag catch button. This category covers AR15 magazine catch buttons built for the AR-15 platform, supporting builders assembling a lower from the ground up as well as those replacing a worn part during routine maintenance.

Our AR15 Magazine Catch Button comes anodized in a five pack — a practical option for builders working on multiple lowers or keeping spares on hand. When choosing, consider platform compatibility for the AR-15, the quantity you need, and the anodized finish for a consistent look on your lower receiver.

Pair these mag catch buttons with other lower controls and stock up on pins and springs to complete your build or maintenance kit.
