San Tan Tactical AR-15 Low Profile Gas Block .750 – Black

The San Tan Tactical Low Profile Gas Block is a drop-in replacement for standard AR-15 gas blocks, designed to sit flush under free-float handguards for a clean, streamlined build. This .750-inch diameter gas block regulates gas flow from the barrel into the gas tube, cycling your rifle's action reliably without adding unnecessary bulk or weight to your setup.

Machined from steel with a durable black finish, this low-profile design eliminates the front sight tower found on standard AR-15 configurations, allowing shooters to run optics or backup iron sights of their choice. Installation requires basic armorer tools and proper alignment with the gas port—gunsmiths recommend using a drill rod or gas block alignment tool to ensure correct positioning. The set screw design provides secure attachment to the barrel.
