The Magpul BEV Block is a bolt-engagement accessory for AR-15 and M4 style rifles that helps you work the rifle with a bolt catch design in mind. Magpul is known for polymer innovations that make modern rifles faster and more comfortable, and this small black part fits into that philosophy by improving how you interact with your magazine and bolt release. Installation is typically simple and tool-light. It is a useful upgrade for shooters who train frequently and like to refine their rifle for smoother manipulation.
