Expert Review Worked as intended - Atrius Development Forced Reset Selector

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.
