UTG AR15 Micro Gas Block – .750" Low Profile with Set Screw Lock

The UTG Micro Gas Block is a low-profile replacement gas block for AR-15 rifles with .750" diameter barrels. This component regulates gas flow from the barrel into the gas tube to cycle the bolt carrier group. Upgrading to a micro gas block allows for free-float handguard installation and a cleaner sight picture compared to traditional front sight base assemblies.

Machined from steel with a matte black finish, this gas block features dual set screws for secure barrel attachment. Installation requires basic tools and careful alignment of the gas tube port—while straightforward for experienced builders, those unfamiliar with AR-15 assembly should consider professional installation to ensure proper gas system function. Includes mounting hardware.
