This Ruger Tech Tip provides instructions on adjusting the gas regulator on the Ruger SFAR rifle. It details the function of different settings (1, 2, and 3) and outlines a method for testing and selecting the optimal setting for reliable cycling, especially when using suppressors or varying ammunition types. The process involves using a 3/16" hex wrench and observing the rifle's cycling behavior.

Quick Summary

The Ruger SFAR gas regulator allows tuning for optimal cycling. Setting three is for lower-powered ammo, setting two for faster unsuppressed loads, and setting one is ideal for suppressed use. Test by firing two rounds; the second should lock the bolt back on an empty magazine, indicating the slowest reliable gas setting.

Frequently Asked Questions

What is the purpose of the gas regulator on a Ruger SFAR?

The gas regulator on the Ruger SFAR controls the amount of gas that cycles the rifle's action. Adjusting it allows you to fine-tune the rifle's performance based on ammunition type, whether it's suppressed or unsuppressed, ensuring reliable cycling without over-gassing.

What is the recommended gas setting for a suppressed Ruger SFAR?

For suppressed shooting with a Ruger SFAR, gas setting one is generally recommended. This setting allows the least amount of gas to flow through the system, which is ideal for managing the increased back pressure caused by a suppressor.

How do I test the correct gas regulator setting on my Ruger SFAR?

To test your Ruger SFAR's gas setting, load two rounds. Fire the first round and confirm it ejects and reloads. The second shot should result in the rifle locking back on an empty magazine. This indicates the lowest reliable gas setting has been found.

What tool is needed to adjust the Ruger SFAR gas regulator?

You will need a 3/16" ball-end hex wrench to adjust the gas regulator on your Ruger SFAR. This tool may have been supplied with your rifle, or you can use a standard one from your toolkit.
