Cmmg Parts Kit Ar15 Magazine Catch

The CMMG Parts Kit AR15 Magazine Catch is a precision-engineered component designed for AR-platform rifle maintenance, repair, and custom builds. This magazine catch assembly handles the critical function of securing and releasing AR magazines with consistent mechanical reliability. Built to CMMG's manufacturing standards, the part delivers the repeatability and durability required for duty rifles, competition platforms, and serious sporting builds where component failure is not an option.

CMMG's approach to parts manufacturing emphasizes tight tolerances and quality control at every stage of production. The magazine catch plays a subtle but essential role in the rifle's ergonomic and functional performance—it must engage and disengage magazines smoothly under various conditions, from rapid tactical reloads to slower precision transitions. The compact design (5 x 0.5 x 3 inches) fits standard AR lower receiver geometry, and the lightweight construction (0.06 lbs) contributes nothing to overall rifle weight while maintaining full mechanical integrity. The existing finish resists corrosion and handles both dry-fire practice and live-fire training without degradation.

This CMMG magazine catch replacement is intended for builders and gunsmiths performing AR15 lower receiver assembly, as well as operators maintaining patrol rifles, training platforms, or precision builds. It serves as a direct replacement when original catches wear, break, or require upgrade as part of a parts kit build. The part's compatibility with standard AR15 magazine designs makes it suitable for any shooter working with common 5.56 NATO, .223 Remington, or intermediate cartridge AR configurations. Whether restoring an older rifle or finishing a new build, this component ensures reliable magazine retention and release throughout the rifle's service life.
