The Strike Industries Modular Magazine Release (brand part number ARMMR) is a steel magazine release built for AR-platform rifles, with a polymer button finished in black. Strike Industries designed it around modularity: the kit includes Standard, Extended, and Oversized buttons so you can match the button size to your hand and shooting style, and swapping between them takes seconds without ever removing the mag catch from the lower. A simple push with any object that fits the gap pops the button free for a fast, tool-light swap. It’s a complete, drop-in upgrade for shooters who want to fine-tune reload speed without a full trigger-group teardown.
