Spike's Tactical Micro Gas Block .625" – AR-15 Low-Profile Steel Block with Set Screws

This Spike's Tactical micro gas block is a low-profile, set-screw design for standard AR-15 barrels with a .625" diameter gas journal. It replaces bulky front sight assemblies or worn gas blocks, giving you a clean profile under free-float handguards while maintaining reliable gas system function. The compact design reduces weight and keeps your build streamlined without sacrificing durability.

Machined from steel with a corrosion-resistant finish, this gas block uses two set screws to secure it to the barrel. Installation is straightforward for builders with basic tools and mechanical familiarity, though proper alignment of the gas port is critical—verify positioning before final tightening. Includes set screws for attachment.
