Most Helpful Positive Review super safe and decision causing
Works fantastic with a RISE 140 trigger. Ive used it with both a auto bolt carrier and non Auto bcg and works the same either way. With an h3 buffer weight and good mags you're ready to rock. My only issue with it is that I have to decide wether I want to conserve ammo while the gremlin in the back of my head is constantly telling me to mag dump just one more time.

Atrius ADG-FRS-AMBI-OD

by Danno, Verified Owner from AL, United States Written on September 15, 2026
Installed correctly and all function/ safety checks were flawless, fired several rounds in semi with no issues. Flipped to FRT and it didn’t make it through the first mag before the reset arm snapped in half. Pot metal. Have been attempting to warranty and no responses as of yet. Very disappointed in this product. I have ran FRT’s on several rifles and never had any issues until now.

love it after some mod.

by Kyle, Verified Owner from NH, United States Written on September 7, 2026
I finally pulled the trigger � and bought one for myself. It says you have to use a "flat" or "squared" rear trigger and cannot use a relief cut one (pish posh). It works fine... after modification. *One the cam on the frt dove tail needs to be sanded down. (Use a flat knife sharpener and then 600 grit !keep it flat faced! And just enough to almost match the cam.) *Two the rear top of the trigger needs to be brought down and slightly rolled more. (Same technique as cam !keep it flat and even!) NO More Than A 10's At A Time!! It's a pain but check it every adjustment till theres no more drag. Watch a you tube video if needed.

Too much hand fitting required

by Scourge, from OH, United States Written on September 2, 2026
I wanted to love it and I may still eventually love it, but I'm into my third attempt at hand fitting and I just feel like this product is not yet ready for prime time. If you don't mind removing metal from a tiny $200 part, then this may be for you, but just remember that you can remove metal but you won't be able to put it back if you don't get it just right.
Pros:
  • OPMOD version is priced a bit lower.
  • Love the OD Green option
  • Appears to be well manufactured
Cons:
  • Fitting and more fitting required
  • Still sort of expensive
Best Used for:
  • fun
  • EOTWAWKI
  • Aggressive home defense
Would recommend: No

Atrius Frt

by otter, Verified Owner from VA, United States Written on July 9, 2026
Finally got my hands on one and after a little bit of fitting it fuctions exactly as expected. I put mine in a psa 11.5 with an h3 buffer and it fuctions without issues.
Pros:
  • cheapest 3 position on the market
Cons:
  • safety cam required a bit of polishing function
Would recommend: Yes

Easy install, great price!

by Rob D, Verified Owner from GA, United States Written on June 28, 2026
Highly recommended item at a great price! Near drop in install, with a slight learning curve. Be sure to install the upper receiver assembled to ensure a proper test of the system (otherwise it was seem as double safety in the third position). Great price for a great product. A+
Pros:
  • Quality
Cons:
  • Learning curve
Best Used for:
  • Range
