Worked As Intended

by Esho, Gear Expert from IL, United States Written on June 18, 2026
Got out to the range to try the standard (non-ambi) Atrius Development Group forced reset selector in a pretty basic setup and figured I’d share what happened.

Rifle was a Smith & Wesson M&P15 running a Rise Armament RA-240 trigger with an H3 buffer.

Going into it I wasn’t sure if I’d end up needing to start swapping parts around or tuning things to get everything happy together, but that never happened. Loaded mags and just started shooting.

The biggest thing that stood out was how uneventful the whole session was—which honestly is exactly what you want. The rifle stayed consistent the whole time and never gave me a reason to stop and mess with it. No chasing problems, no adjustments between strings, no “maybe this next mag will tell the real story.”

By the end of the range session I had put 6 full magazines through it and realized I hadn’t had a single issue the entire time. For this particular combination, the M&P15 + RA-240 + H3 buffer seemed to work together really well. Once I got into the rhythm, it just stayed there and kept running.

I know every rifle can behave differently and results can depend on the exact parts used, but if anyone is curious about this setup specifically, my experience was straightforward: install it, take it out, and shoot it.

Final tally for the day: six magazines downrange and nothing to complain about.

Ensure you have a low shelf lower, a H2 or H3 buffer and follow the installation instructions/online videos on how to do a proper function test after reassembly. (order more ammo while when you place your order---you'll need it!!)
Most Helpful Negative Review Unfortunate
I really wanted to like this. Got it installed, moved freely. Went to rack it to check tolerance and it shattered. Not mortaring not racking hard, just trying to check clearance and score as per Atrius directions. Shattered in like 10 pieces. Theres no way this would handle the bolt cycling. Like I ...

Awesome!!!

by Adam Coles, Verified Owner from OH, United States Written on September 14, 2026
I was hesitant after watching videos on these things occasionally breaking. The only thing I can say is don't just throw this thing in and try to run it. Take your time and function test. There are plenty of videos on YouTube demonstrating this. It's very simple. All I had to do was fine tune the top/back 1/4" of the trigger. Granted I had the trigger in and out of the lower 9 or 10 times to make sure I took just enough off to function. Well worth the time and money.

Buyer beware

by Chris Arnold, Verified Owner from IN, United States Written on September 8, 2026
I received the selector and installed it on my riffle it was defective detent holes machined in cam are not at 0-90-180 they are off at least 25 degrees when selector is in normal semi mode rifle will not fire. you have to manually hold selector at 90 degrees before it will fire. Contacted Atrius told them it was defective and even though they say there is a 1 year warranty from defects, they said I have to return it to Optics Planet and optics Planet says these items are final sale and not eligible for returns or exchanges. So now I'm out $199.00 and no one will do anything. I would not buy this product !!!

A must have for the build enthusiast

by AggOwl, Verified Owner from TX, United States Written on August 30, 2026
Easy to install and tune. A great alternative to an FRT that is compatible with many mill spec and drop in cassette triggers.
Works with Rise Armament Rave 140, Blitz, RA-434, LE145 and others as well as Schmid Tool Combat Trigger and Dirty Bird Single-Stage Nickel Teflon trigger.
Pros:
  • Easy Insallation
  • compatibility list
Cons:
  • not drop in cassette
Would recommend: Yes

go brrrrrrrraaaaattttt

by cubanhitman, Verified Owner from TX, United States Written on August 29, 2026
This thing works great. Just make sure you have an H2 or H3. H2 will be a little more finicky towards the 55 grain. (In my experience) Also make sure that your set will work with this. (Trigger group ect..) but when this thing goes it goes. Prepare to burn through some ammo.
