Wilson Combat TRLPGBM Low Profile Gas Block .875" Black Nitride

The Wilson Combat TRLPGBM Low Profile Gas Block delivers precise gas regulation for AR-15 builds requiring maximum accuracy and reliability. This .875" diameter gas block features black nitride coating over 4140 chromoly steel construction for enhanced corrosion resistance and extended service life.

What Makes This Different

Unlike standard gas blocks that can interfere with free-floating handguards, this low-profile design sits flush beneath most rail systems. The precision-machined 4140 chromoly steel construction provides superior strength compared to standard carbon steel alternatives. Black nitride treatment penetrates the steel surface, creating a finish that resists wear and corrosion better than traditional Parkerizing or phosphate coatings.

Key Features

• Low-profile design fits under free-floating handguards without interference
• 4140 chromoly steel construction for enhanced strength and durability
• Black nitride finish provides superior corrosion and wear resistance
• .875" journal diameter fits standard AR-15 barrel profiles
• Precision gas port alignment ensures consistent cycling
• Set screw retention system for secure barrel attachment
• Compatible with standard .750" gas tubes

This gas block maintains consistent gas pressure across temperature extremes and high round counts. The low-profile design eliminates the bulk of traditional front sight base assemblies while maintaining reliable function in competition, tactical, and hunting applications. Black nitride coating withstands exposure to cleaning solvents, carbon fouling, and environmental moisture without degradation.
