WMD Guns
Overview
The WMD Guns NiB-X AR-15 Bolt Catch features a Nickel Boron finish that enhances durability and provides smooth operation, making it easier to engage and release your bolt during reloads. This finish also helps reduce friction and wear, which is particularly beneficial for high-use builds. You’ll often find this bolt catch in mid-length gas system builds chambered in 5.56 NATO, where reliability and performance are key.
