Gas Block Genie Gas Block - Alignment Tool For Ar-15

The Gas Block Genie Gas Block Alignment Tool for AR-15 solves one of the most common accuracy and reliability issues encountered during platform assembly and maintenance. Whether you're a gunsmith, armorer, or serious competitor, proper gas block alignment directly impacts bolt carrier group cycling, suppressor performance, and overall system reliability. Misaligned gas blocks—even by a fraction of an inch—create uneven gas port contact, leading to short-stroking, carrier tilt, and accelerated component wear. This specialized tool eliminates guesswork by ensuring your gas block sits perfectly centered on the barrel journal before installation.

Engineered by Two Two Three Innovations, the Gas Block Genie uses a precision-fit design that accommodates standard AR-15 barrel profiles and common gas block configurations. The tool's compact dimensions (2.7 x 1.25 x 4.2 inches) and minimal weight (0.05 lbs) make it lightweight enough for field use while maintaining the rigidity required for accurate centering. By mechanically aligning the gas block perpendicular to the barrel axis before tightening set screws, this tool prevents the radial misalignment that typically occurs when blocks are hand-fitted or installed without reference geometry. The result is consistent gas tube alignment, optimal pressure regulation, and repeatable bolt lock times across high round counts.

Ideal for AR-15 builders, professional armorers, law enforcement gunsmiths, and rifle competitors, the Gas Block Genie is essential for any build where precision and long-term reliability matter. Use it during initial assembly to verify alignment before final torque, or deploy it as a diagnostic tool when troubleshooting short-stroke or over-gas issues on existing rifles. The tool works with standard 0.750-inch diameter gas blocks and fits all common AR-15 barrel profiles, making it a universal solution across mil-spec and match-grade builds. Installation is straightforward: slide the tool over the barrel journal, position your gas block, and verify centered contact before permanent installation.
