WMD Guns Disconnect Semi NiB-X Nickel. The NiB-X provides for a cleaner more reliable disconnect by preventing any ricochet or snag when firing. It also reduces trigger over-travel and drag when the disconnector is inserted too far. The NiB-X disconnector has a larger contact surface and radiuses trigger pulls improving tactile feedback to the shooter. It can be installed by the shooter in seconds and does not require any gunsmithing to install. However due to the exceptionally heavy buffer springs used in some of the more powerful firearms the NiB-X needs to be installed by a competent and qualified gunsmith in order to avoid damage to the shooter or the firearm.
