A quality gas block is fundamental to a reliable AR-platform rifle build, and the San Tan Tactical .750 diameter low profile black gas block delivers the precision engineering needed for consistent performance. This low-profile design is built to mount cleanly on mid-length or carbine-length AR gas tubes, keeping your setup compact without sacrificing the positive lock and repeatable function you need downrange. Whether you're assembling an AR for hunting, 3-gun competition, or precision rifle work, a purpose-built gas block that holds zero matters more than most shooters realize.
San Tan Tactical manufactures to exacting standards, and this .750 gas block reflects that commitment to durability and reliability. The low-profile profile minimizes interference with optics mounting systems and rail real estate, giving you flexibility in how you set up your rifle. Black anodizing provides corrosion resistance and a clean aesthetic that integrates seamlessly with modern AR builds.
Installation is straightforward for anyone comfortable with basic AR work—it's a core component for custom builders who want parts they can trust. Pair it with quality staking hardware and a properly set gas tube, and you have a gas block that will function reliably through thousands of rounds without creep or shift.

The .750 diameter is the industry standard bore size for mid-length and carbine-length AR-15 gas tubes. Confirm your gas tube diameter before purchase to ensure proper fit.
Low-profile gas blocks are designed to minimize obstruction on top of the upper receiver, leaving more room for optics mounts and Picatinny rail systems than full-height blocks.
This gas block is designed for AR-15 platforms using a .750 diameter gas tube. Verify your rifle's gas tube diameter and length before ordering.
The product record does not specify what hardware is included or required for installation. Contact Bosque Outdoors or San Tan Tactical directly to confirm what fasteners and staking materials you'll need for your build.
