Advanced Technology Micro .750 Low Profile AR-15 Gas Block - Matte Black Steel

The Advanced Technology Micro .750 Low Profile Gas Block is a direct-fit replacement for the AR-15 platform, designed to seat cleanly on .750" diameter barrel gas journals. Its low-profile housing tucks under free-float handguards without the bulk of a fixed front sight tower, freeing rail space for optics, lights, and accessories.

Machined from steel and finished in a non-reflective matte black coating, this gas block seals against the barrel gas port and channels cycling gas into the AR-15 gas tube. It installs with two mounting screws and ships as a no-front-sight replacement, making it a clean solution for modern flat-top upper builds and gas-system service work.

Engineered for AR-15 pattern rifles with a .750" gas journal, the Advanced Technology Micro Low Profile Gas Block delivers a streamlined, low-profile fit for custom builds, rebuilds, and replacement of damaged or worn gas system components.
