The LBE mag catch assembly did its job. It engages the magazine reliably and releases it when pressed. I didn't have any fitting issues during assembly on my AR pistol lower. It's just a functional piece, nothing fancy, which is what I needed.

The LBE mag catch assembly did its job. It engages the magazine reliably and releases it when pressed. I didn't have any fitting issues during assembly on my AR pistol lower. It's just a functional piece, nothing fancy, which is what I needed.
Used this on a recent 5.56 build. No issues with mag seating or release. It's a basic part but functions exactly as it should. Good for a standard setup.
