Introducing the Strike Industries AR Modular Bolt Catch, a game-changing component for AR-15s. For many shooters, the bolt catch is simply a control they have to deal with, but this modular bolt catch gives you the ability to customize your setup to your liking. With four different buttons included in the kit, you can choose between Standard, Oversized, Left Extended, and Right Extended, providing options that suit your needs. The bolt catches are made of a durable polymer with a textured surface on a steel base, making them lightweight and easy to use.
 
Installation is a breeze with the provided hex key. Just remove the set screw holding the current bolt catch in place, slide it off its base, and replace it with the button of your choice. You won't even have to mess with the roll pin in your lower receiver. The full kit includes everything you need, even the bolt-catch roll pin and spring, making the installation process as simple as possible. Say goodbye to dealing with the bolt catch you settled for and hello to a custom configuration that works best for you.
