The Ed Brown low profile magwell offers a larger and improved opening to aid in faster mag changes, while being low profile enough for daily carry, and competition legal. Installs easily with a rigid mounting system that will hold it in place for thousands of reloads. Profiled to look like factory equipment, and fully machined from aluminum and black anodized for a lifetime of service. Complete with the Ed Brown logo. Designed for M&P® 2.0™, and compatible only with Ed Brown M&P® mag basepads. May not work with the stock mag bases, or other aftermarket bases.
