Guntech AR-15 Adjustable Steel Low Profile Gas Block

The AR-15 Adjustable Steel Low Profile Gas Block (.750 Diameter) is engineered for builders who want precise control over their rifle’s gas system without sacrificing durability or compatibility. Designed to fit .750″ diameter barrels, this gas block is ideal for tuning rifles chambered in 5.56, .308, and 9mm where managing gas flow is critical for reliability and recoil reduction.

Manufactured in the USA from steel, this gas block offers excellent heat resistance and long-term durability. The fully adjustable set-screw design allows the user to fine-tune gas flow to match their specific setup—making it especially useful for suppressed rifles, over-gassed builds, or performance-focused configurations.

The low-profile design fits under most free-float handguards, while the black oxide finish provides corrosion resistance and a clean, non-reflective appearance. Compact dimensions and lightweight construction ensure strength without unnecessary bulk.
