Faxon Firearms GBLP7503 Low Profile Gas Block .750" 4150 Steel

The Faxon Firearms GBLP7503 Low Profile Gas Block delivers precise gas regulation for .750" barrel builds while maintaining a clean, streamlined profile under handguards. This 4150 steel gas block eliminates the bulk of traditional front sight bases, creating optimal clearance for modern free-float rail systems.

What Makes This Different

Unlike standard A2 front sight bases that add unnecessary height and weight, the GBLP7503 sits flush against the barrel with minimal vertical clearance. The machined 4150 steel construction provides superior durability compared to cast alternatives, while the precision-drilled gas port ensures consistent pressure regulation. This low-profile design allows shooters to mount optics at proper eye relief without interference from protruding gas blocks.

Key Features

• 4150 steel construction for enhanced durability and heat resistance
• .750" inner diameter fits standard medium contour AR-15 barrels
• Low-profile design clears free-float handguards and rail systems
• Precision-machined gas port maintains consistent pressure regulation
• Set screw installation with dimpling capability for secure attachment
• Nitride finish resists corrosion and reduces maintenance requirements
• Compatible with standard .093" gas tubes and carbine/mid-length systems

Field performance remains consistent across temperature extremes and extended firing sessions. The 4150 steel material withstands the thermal stress of rapid-fire sequences without dimensional changes that could affect gas system timing. Competition shooters benefit from the reduced reciprocating mass, while tactical users appreciate the unobstructed sight picture and accessory mounting options.
