One Horse Low-Profile Steel Gas Block, .750in

The One Horse Low-Profile Steel Gas Block (part no. OHGB01) is machined from steel with a .750-inch bore to fit standard .750 barrel journals. One Horse keeps the profile low enough to clear most free-float handguards, and it clamps on with set screws rather than a pinned or clamp-on collar design.
