CMMG PARTS KIT AR15 MAGAZINE CATCH

Description

The magazine catch is one of those components that draws no attention when it works and causes immediate problems when it doesn’t. CMMG’s AR-15 Magazine Catch Parts Kit gives you everything needed to replace or build out the magazine retention assembly on a standard AR-15 lower receiver — the catch body, the button, and the spring — so you’re not hunting for individual pieces separately.

The catch engages the magazine notch and holds the mag firmly in the well under the tension of the spring. When the button is pressed, it rotates the catch clear of the notch and allows the magazine to drop free. A weak or worn spring, a damaged catch body, or a button that binds in its channel are the most common causes of magazines dropping unintentionally or refusing to release cleanly — this kit addresses all three at once rather than leaving you to guess which part is the source of the problem.

CMMG builds to mil-spec AR-15 dimensions, so this kit fits any standard AR-15 lower receiver that accepts a DPMS-pattern magazine catch. As noted by a verified retailer Q&A, it is also compatible with .308/AR-10 pattern lowers that share the same magazine catch geometry, such as the Aero Precision M5E1. It’s a straightforward replacement for a build or a rebuild, and having a complete spare kit on hand means a malfunctioning magazine catch doesn’t end a range session.
