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.

WMD NiB-X bolt catch is 10/10 for a NiB themed build. The slick NiB coating matches my WMD BCG. Mechanically perfect with smooth pivot action. Drops in any milspec lower with the standard catch spring.
WMD NiB-X bolt catch has the slick nickel boron finish thats slightly more shiny than the photos suggest. Function is correct, drops in any milspec lower. The NiB coating wears well over time and cleans easily.
