WMD Guns NIB-X Gas Block Low Profile .750

The WMD Guns NIB-X Gas Block is a low-profile .750" diameter gas block designed for AR-15 platforms with standard barrel profiles. This component regulates gas flow from the barrel to the gas tube, cycling the bolt carrier group. The low-profile design sits beneath most free-float handguards for a clean, streamlined appearance without the bulk of traditional front sight base assemblies.

Coated with WMD's proprietary Nickel Boron-X (NIB-X) finish, this gas block offers exceptional hardness and lubricity compared to standard phosphate or nitride finishes. The NIB-X coating resists carbon buildup and heat, simplifying cleaning after extended shooting sessions. Installation requires set screws to secure the block to the barrel—proper torque and alignment with the gas port are critical for reliable function. Most builders with basic tools can install this gas block, though first-time builders may benefit from a gunsmith to ensure correct gas port alignment.
