Armaspec ECB Magazine Release Button

The Armaspec ECB Magazine Release Button, Black (brand part no. ARM204-BLK) is a direct upgrade for the magazine release button on a standard mil-spec AR-15 lower receiver. Armaspec built the ECB for shooters who want extra texture on the release for faster, more positive magazine changes without stepping up to a bulky, oversized paddle. The button keeps a small, low-profile footprint that will not snag on gear or catch inadvertently, while still giving a shooter’s thumb something to grab under stress or with gloved hands. It is a simple drop-in swap for the factory magazine release button on a mil-spec lower.

Key Specifications

• Adds a textured release surface over the smooth factory button for faster, more positive magazine changes.
• Keeps a low-profile footprint, avoiding the snag risk of an oversized paddle-style release.
• Built as a direct replacement for the magazine release button on a standard mil-spec AR-15 lower.

Frequently Asked Questions

Does this replace the whole magazine catch assembly? No, it replaces just the button, dropping into a standard mil-spec magazine catch assembly.

Why choose a low-profile button over a paddle release? It adds grip texture for faster mag changes while keeping the same small footprint as the factory button, avoiding snag risk.
