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:Â T10 screw, 4/40 thread, selector spring. We recommend 15 in/lbs with blue loctite only.
Please Note:Â 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:Â All modifications should be performed by a qualified gunsmith. Improper installation or unauthorized modification may result in malfunction or unsafe operation.

Brrt
Works great. Some triggers need modification(sanding, filing), even if they’re on the list, in my experience. Using a suppressor is likely going to require a heavier buffer and spring. If you’re fire arm is not cycling and acting as if it’s not gassed enough, it’s more than likely too much gas and causing bolt bounce and the hammer to follow the bolt back into battery, causing a dead trigger. You’ll need a heavier buffer and or spring or adj. gas block.
USSuper Perfect and Super Fun!
I've been waiting to do that for 50 years! It's as awesome as I thought it would be, maybe more. I heard a collective cheer at the range after I shot my first burst. The installation was easy. I changed the buffer weight to H3 for a carbine with a 16" barrel. It worked perfectly. It worked fine in semi-auto with the heavier buffer. The bolt locked to the rear after the last round. Treat yourself and get one.

USPatience
After some trial and error this thing rocks. Got it tuned for my can and it’s unbelievable. You will not be disappointed. Just be patient and you’ll be rewarded. The buddy who helped me with this had no experience with Atrius. He now says he won’t buy anything else.
