Geissele Super Gas Block .750" Steel Black Nitride AR-15 AR-10

The Geissele Automatics Super Gas Block delivers precision gas regulation for AR platform rifles with enhanced durability and corrosion resistance. This low-profile gas block features premium steel construction with black nitride coating for extended service life.

What Makes This Different

Unlike standard gas blocks that rely on basic steel construction, the Geissele Super Gas Block incorporates precision machining tolerances and black nitride surface treatment. The nitride coating provides superior corrosion resistance compared to phosphate or bare steel alternatives. This gas block maintains consistent gas pressure regulation across temperature extremes and high round counts.

Key Features

• Precision-machined steel construction with black nitride finish
• .750" diameter fits standard AR-15 and AR-10 barrel profiles
• Low-profile design clears most free-float handguards
• Corrosion-resistant nitride coating extends component life
• Set screw installation with proper torque specifications
• Compatible with carbine and mid-length gas systems
• Maintains proper headspace and timing alignment

Field testing demonstrates reliable cycling across various ammunition weights and environmental conditions. The nitride coating resists fouling buildup and maintains smooth operation through extended firing sessions. Competition shooters and duty users report consistent performance in high-volume applications where gas system reliability becomes critical.
