Modular Action Wrench for Aero Precision Solus

The Modular Action Wrench for Aero Precision Solus is a professional-grade, heavy-duty wrench built for gunsmiths, precision rifle builders, and enthusiasts who demand maximum strength, precision, and flexibility. This modular design lets you service not just the Solus action, but a growing lineup of bolt-action platforms — all with a single tool.

Machined from 4140 steel, the Modular Solus Wrench is designed to withstand the torque and stress of repeated barrel installations and removals. The phosphate coating enhances corrosion resistance and surface hardness, ensuring years of reliable use in both shop and field environments.

At one end, the Solus Action Wrench integrates multiple fastening interfaces: a 7/8″ hex for standard action nuts, a 1/2″ socket drive for direct use with breaker bars or torque wrenches, and wrench flats compatible with adjustable or open-end wrenches. This triple-purpose design makes the tool incredibly versatile — equally suited for precision assembly, maintenance, or field adjustments.

The opposite end of the Solus modular Action Wrench features a robust modular interface that accepts interchangeable bolt-head adapters. Each adapter head is secured with precision alignment to ensure consistent torque transfer and perfect engagement with the action. The wrench ships standard with the Aero Precision Solus Action head, while additional heads for popular platforms such as Tikka, Bergara, and Remington 700 are in development. This modular approach saves both cost and storage space — giving builders one universal wrench body with swap-in heads for multiple rifles.

Built for Durability and Control

The Modular Action Wrench for Aero Precision Solus is engineered for smooth, repeatable torque application. Use the 1/2″ socket drive with a calibrated torque wrench to achieve the manufacturer-recommended torque spec, or use the wrench flats for quick hand-tightening when adjustments are needed on the fly.

The 4140 steel construction provides excellent tensile strength, fatigue resistance, and dimensional stability under heavy loads. Combined with a phosphate finish, it resists wear, galling, and surface corrosion even under heavy shop use.

Modular Compatibility and Future Expansion

As more modular heads are released, this Solus modular Action Wrench becomes an investment that grows with your armory. Rather than buying new wrenches for each action type, you can simply attach a new bolt-head adapter — reducing tool redundancy and maintaining precise fit across different platforms.

This modular wrench design simplifies workflow for professional gunsmiths and hobbyists alike, offering compatibility, repeatability, and confidence during each installation or teardown.

Practical Use and Recommendations

When using the Solus Action Wrench, always verify torque requirements for your specific rifle action. The integrated 1/2″ socket drive allows for direct torque wrench use, while the 7/8″ hex and wrench flats support flexible setups in any workshop environment. For best longevity, lightly oil the phosphate finish after cleaning to protect against oxidation.
