Jun
Looking for the best forced reset trigger for your AR-15? The honest answer is that the right one depends on your build and how much setup you want to do. Below are the forced reset triggers we stock and stand behind in 2026 — all of them fire one round per trigger pull and keep your rifle semi-automatic — plus how to pick between them.
We sell these every day at FRT Triggers USA, so this is a buyer’s guide based on what actually works on customer builds, not a paid ranking.

How to choose a forced reset trigger
Three things decide it: how plug-and-play you want it (a complete drop-in cassette is the easiest), platform compatibility (AR-15 vs other hosts), and whether you want to keep your own trigger (selector-based systems work with an existing fire-control group). Price follows from there.
Our top forced reset triggers
1. Partisan Disruptor FRT — best drop-in. A true drop-in 3-position cassette (Safe, Semi, Enhanced Semi) with no gunsmithing. Tool-steel and 4140 chromoly wear surfaces, 3.75–4.1 lb pull. The simplest path for most AR-15 owners. $265.
2. AS Designs ARC-Fire Ambi Kit — best multi-platform. Ambidextrous Active Reset Clutch system that fits AR-15, MCX, MPX, MP5, G3/91 and more (some need a platform kit). Ships with a pre-cut trigger. $230.
3. Atrius Forced Reset Selector (Super Selektor) — best if you want to keep your trigger. A selector-based system (Safe, Semi, Full-Semi) machined from heat-treated 4140 steel that works with many mil-spec triggers. From $180.
The brand that pioneered the category, Rare Breed, is also worth knowing — see our Rare Breed FRT triggers and our full forced reset trigger brands guide.

What your build needs
Whatever you pick, plan on a full-auto bolt carrier group and a heavier H2 or H3 buffer for reliable cycling, especially on 16-inch or shorter carbines. Selector-based systems may also need an FA-pocket lower and a trigger with a super-safety cut. New to all this? Start with what a forced reset trigger is.

Frequently asked questions

A true drop-in cassette like the Partisan Disruptor is the most beginner-friendly because it installs without gunsmithing or fitting.
Are these forced reset triggers legal?
They are legal under federal law after the May 2025 DOJ settlement, but some states restrict them. Confirm your state and local law before ordering.
Do I need a special bolt carrier for an FRT?
A full-auto bolt carrier group and a heavier buffer are strongly recommended for consistent cycling and reliable reset.
