Faxon Firearms GBALP7503 Low Profile Gas Block .750" AR-15 Steel

The Faxon Firearms GBALP7503 Low Profile Gas Block delivers precise gas regulation for AR-15 builds requiring a clean, streamlined appearance. This steel gas block eliminates the bulk of traditional front sight bases while maintaining reliable gas system function. Built to .750" barrel specifications, it provides consistent cycling across various ammunition weights and barrel lengths.

What Makes This Different

Unlike standard A2 front sight bases, this low profile design sits flush beneath free-floating handguards without interference. The machined steel construction provides superior heat resistance compared to aluminum alternatives, maintaining dimensional stability during rapid fire sequences. Precise bore alignment ensures optimal gas port registration, while the compact profile reduces overall rifle weight by approximately 2-3 ounces versus traditional gas blocks.

Key Features

• Machined steel construction for maximum durability and heat resistance
• .750" bore diameter fits standard mid-length and carbine gas systems
• Low profile design compatible with free-floating handguards
• Set screw installation with included hardware for secure barrel mounting
• Mil-spec gas port positioning for reliable cycling
• Black oxide finish provides corrosion resistance
• Compatible with standard .223/5.56 NATO chambered barrels

Field testing demonstrates consistent cycling with ammunition ranging from 55-grain to 77-grain projectiles. The steel construction maintains gas port alignment under sustained fire conditions where aluminum blocks may shift. Installation requires basic armorer tools and torque specifications, making it suitable for home builders and professional gunsmiths alike. The low profile eliminates snagging points while maintaining full compatibility with various muzzle devices and suppressor systems.
