TROY Industries .875 Gas Block – AR-15/M16 Low-Profile

The TROY .875 gas block is a precision-machined component designed to regulate gas flow in AR-15 and M16 pattern rifles with .875-inch diameter barrels. This low-profile design sits beneath most free-float handguards, providing a clean installation without the bulk of a traditional front sight tower. Upgrading to this gas block allows shooters to run extended rail systems and mount optics or backup sights at their preferred positions.

Machined from steel with a durable black finish, this gas block is built to withstand the heat and pressure of sustained firing. Installation requires removal of the existing gas block and basic gunsmithing tools, though professional installation is recommended for those unfamiliar with barrel components. The low-profile design ensures compatibility with modern handguard systems while maintaining reliable gas system function.
