Double check your compatibility.
Below are the minimum firearm requirements:
- Low shelf or Full Profile Trigger Pocket lower receiver
- Full Profile BCG
- H2 or H3 buffer
- Trigger from our compatibility list below
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.
