Frequently Asked Questions

1. Is this safety selector compatible with my standard AR-15?
Yes, it fits mil-spec AR-15 platforms chambered in .223/5.56 or .300 BLK without requiring fire control group modifications. For best results, use an H2 or H3 buffer and ensure your BCG is properly tuned.

2. What does the SUPER-SEMI position do?
The SUPER-SEMI mode enables a forced reset mechanism, allowing for faster follow-up shots in semi-auto configuration, simulating rapid fire while remaining fully compliant with standard firearm operations.

3. How easy is installation?
Installation is straightforward as a drop-in replacement. Use the included T10 screw with blue Loctite, torque to 15 in-lbs, and test for proper function—typically completed in minutes without special tools.

Compatibility Notice:

• Certain platforms, such as AR9 variants, may require professional gunsmithing to ensure proper function of the selector lever.

• Firearms modified to “Super Safety” specifications may not be compatible with components designed for our FRS system, as the Atrius Safety Device features a solid lever cam design.

• The Super Safety system incorporates a 15-degree tolerance due to its dovetail construction, which may allow for limited over-travel before the cam surface disengages from the trigger bar.

Selector Screw and Torque Spec: T10 screw, 4/40 thread, selector spring. We recommend 15 in/lbs with blue loctite only.

Please Note: This Atrius FRS will not work with AR-10(LR308)/SR-25 platforms without significant gunsmithing. In the near future we will be coming out with a model specifically catered to these platforms.

Important: All modifications should be performed by a qualified gunsmith. Improper installation or unauthorized modification may result in malfunction or unsafe operation. Use and modify at your own risk. The manufacturer assumes no liability for damages or injuries resulting from incorrect installation or use outside of intended specifications.
