Faxon Low Profile Gas Block - .750 Dia 3 Screw Nitride

The Faxon Low Profile Gas Block - .750 Dia 3 Screw Nitride is a precision-engineered barrel accessory designed for serious rifle builders and operators who demand reliable, repeatable performance in custom AR-platform builds. This low-profile gas block is engineered to regulate propellant gases with minimal visual signature and weight penalty, making it ideal for tactical, competition, and precision rifle applications where traditional full-height blocks compromise sight lines or add unnecessary bulk. The three-screw design provides redundant securing points, ensuring zero movement under sustained fire conditions.

Manufactured from high-strength steel and finished in corrosion-resistant nitride, the Faxon gas block is built to withstand the thermal cycling and mechanical stress inherent in modern rifle operation. The .750-inch barrel diameter specification ensures proper fitment on mid-length and rifle-length gas system configurations common in modern AR-15 and AR-10 builds. The skeletonized, lightweight design reduces overall rifle weight while maintaining structural rigidity, and the three set-screw fastening system—without roll pin dependency—allows for tool-free field adjustments and removal. Nitride surface treatment provides superior corrosion resistance compared to bare steel, ensuring long-term reliability in harsh environments.

This gas block is ideal for precision rifle builders, military and law enforcement armorer-led custom builds, and competition shooters who prioritize accuracy and reliability over off-the-shelf convenience. Its low-profile design integrates seamlessly with optic mounting systems and rail-mounted accessories without interference, making it particularly valuable in modern combat rifle platforms. Proper installation requires verification of correct barrel diameter and set-screw torque specifications; consult your rifle manufacturer's guidance or a qualified armorer to ensure optimal performance. Compatible with .750-inch diameter barrels on mid-length to rifle-length gas tube systems.
