Works with Atrius Super Selektor

by S. Templar, D.D., Verified Owner from WV, United States Written on November 20, 2025
I have now installed 3 of these Rise RA140 "join or die" triggers on three different AR-15 lowers. Lowers from Colt, BCM, and Chelsea Firearms.

All three were absolute drop in perfection. No fitting, no futzing, no challenges at all. Dropped them in, installed the Atrius safeties, BAM! Done and done.

They instantly passed all the benchmark tests. I couldn't be happier about it.

I know there a lot of ideas floating around about one trigger or another. These Rise 140's are three for three, for me.

If you are looking for a drop-in trigger for your Atrius build... look no further. For around $100 you can get an aerospace grade trigger that absolutely rocks with the Atrius.

Definitely recommend. AAA+++

I love this Trigger

by Tony, from TN, United States Written on March 8, 2025
I love the smooth transition when firing. It’s not like the regular factory trigger. It rests faster so you can shoot right away again.

Drop-In Trigger

by BuffMan, Verified Owner from VA, United States Written on November 12, 2024
This is my fourth Rise Armament “ cassette “ trigger. They feel great, like a thin glass rod, no creep or grit at all. The ease of installation combined with the included anti-walk pins makes for a great addition to my AR-10 platforms. Turned a cheap BCA lower into a quality tool that’s easy to tinker with.
Pros:
  • Complete Unit
Cons:
  • None
Best Used for:
  • AR-10 and AR-15
Would recommend: Yes

Solid Buy!

by Nafton Colder, Verified Owner from FL, United States Written on September 21, 2024
Dropped this into my PSA lower (300 blackout). Worked perfectly. Incredibly clean break, made precision shots, a lot easier than the factory trigger.
