The button features deep serrations and an ergonomic shape to facilitate positive engagement with the finger, and its design makes the button easier to find in dark or adverse conditions for a tactical advantage. At a gross weight of just 0.6 ounces, this magazine catch assembly is perfect for your next lightweight AR build. Each assembly comes with a release, enhanced magazine catch and spring.
