Faxon Firearms Adjustable .750 Low Profile Gas Block 3-Screw GBA-LP-750-3

Short Product Description

The Faxon Firearms Adjustable .750" Low Profile Gas Block features a three-screw mounting system, 14 tactile adjustment settings, and a design that meters gas by moving the gas tube rather than placing the adjustment screw directly in the gas path. This configuration is designed for barrels with a .750" gas journal.

Machined from 4140 chromoly steel and finished with flash nitride, the low-profile gas block measures 1.000" long, .639" wide, and 1.350" overall height. It accepts standard AR gas tubes in pistol, carbine, mid-length, or rifle lengths, which are sold separately.

Product Highlights

The Faxon adjustable gas block uses a patent-pending adjustment system that moves the gas tube to control the amount of gas entering the tube. Its adjustment screw is kept out of the gas stream, while a spring-loaded detent provides 14 tactile settings that hold the selected position.

The low-profile design is intended to fit under most free-float handguards, and the three set screws provide three points of contact around the .750" barrel gas journal.

Benefits

• 14 tactile settings provide repeatable gas adjustment
• Adjustment screw stays outside the gas path
• Three set screws provide multiple mounting points

• 4140 steel construction provides the specified material strength and composition
• Flash nitride finish provides the specified surface treatment
• Compatible with standard AR gas tubes in multiple lengths
• Mil-spec gas tube height supports compatibility with standard AR gas systems

Considerations

• Gas tube is sold separately.
• Designed for barrels with a .750" gas journal.
• Requires at least 1.000" of journal length ahead of the barrel shoulder.
• Allow approximately 1.350" of clearance beneath the handguard.
• Verify barrel gas-journal diameter and handguard clearance before installation.
• Compatible with direct-impingement AR platforms using a .750" gas journal.

Ideal Use

Ideal for AR-15, AR-10, LR-308, and other compatible direct-impingement AR platforms using a .750" gas journal and a standard AR gas tube.
