Overview
The WMD Guns Nitromet AR-15 Bolt Catch is a standard-type bolt catch made from durable steel and finished with a nitride coating for enhanced corrosion resistance and durability. This component plays a crucial role in the operation of your rifle by holding the bolt open after the last round is fired, allowing for quick and efficient reloading. This bolt catch is commonly found in mid-length gas system builds chambered in 5.56 NATO, making it a reliable choice for those setups.
