Frequently Asked Questions

What are the essential tools for disassembling the Ruger SFAR rifle?

For Ruger SFAR disassembly, you'll need a soft-faced hammer, a 3/16" ball-end Allen wrench, a 5/32" Allen wrench, a 1/16" punch, a non-marring punch (like nylon or wood), and safety glasses. The 3/16" Allen wrench is crucial for gas regulator adjustments.

How do you safely begin disassembling the Ruger SFAR?

Begin by ensuring the rifle is completely empty of live ammunition and that your workspace is clear. Engage the safety, remove the magazine, pull the charging handle to the rear, engage the bolt lock, and visually confirm the chamber is empty.

What is the function of the gas regulator on the Ruger SFAR?

The gas regulator on the Ruger SFAR allows you to adjust the gas system's pressure output. It has four settings (0-3) to optimize cycling for different ammunition types, from low-pressure subsonic rounds to higher-pressure loads, and for use with suppressors.

How do you adjust the gas regulator on the Ruger SFAR?

Use the supplied 3/16" ball-ended Allen wrench to adjust the gas regulator. Depress the plunger stop at the front of the regulator, rotate it until the flat aligns with the underside of the hood, and then pull it out. Always use the lowest setting that reliably cycles the action.
