Armaspec B1 Extended Magazine Release – Black | AR-15 Upgrade

Upgrade your AR-15 with the Armaspec B1 Extended Magazine Release in Black. Designed as a direct drop-in replacement for the standard mil-spec mag release button, the B1 features an extended profile that allows for faster, more positive magazine changes — a critical advantage in competition, training, and tactical applications. The extended surface area gives your thumb or fingers a larger contact point, reducing fumble and improving reload speed without requiring permanent modification to your lower receiver.

Built to Armaspec’s renowned quality standards, this extended mag release offers a durable, corrosion-resistant black finish that blends seamlessly with most AR-15 builds. Its compact dimensions (0.80″ x 3.25″ x 5.55″) make it a low-profile upgrade that won’t snag on gear or interfere with your shooting grip.

Compatible with standard AR-15 lower receivers. Please note: This item is NOT available for direct shipment to California.
