Black Rain Ordnance
Overview
The Black Rain Ordnance Bolt Catch is a durable steel component designed to securely hold the bolt in the open position after the last round has been fired, allowing for easier magazine changes. Its phosphate finish offers enhanced corrosion resistance while maintaining a sleek black appearance that fits seamlessly into any build. This bolt catch is commonly found in carbine gas system builds chambered in 5.56 NATO, making it a reliable choice for those configurations.
