Atrius Forced Reset Selector – Super Selektor

The Atrius Forced Reset Selector (Super Selektor) is a forced reset selector device for the AR-15 that gives the shooter three selector positions — Safe, Semi (traditional), and Full-Semi — while firing one round per trigger pull. A standout in our Super Safety trigger lineup, it installs in place of your factory safety selector and is built to work with mil-spec AR-15 fire control groups chambered in .223/5.56 and .300 BLK.

The Atrius Forced Reset Selector fires one round per trigger pull and, after the May 2025 DOJ settlement, forced reset triggers of this type are not classified as machine guns under federal law. State and local laws vary, so confirm yours before buying. You must be of legal age and eligible under federal, state, and local law to purchase.

Specifications and fitment

What you need for reliable operation

The Super Selektor is designed for mil-spec triggers without a relief cut — the rear of the lower half of the trigger must be squared off with no U-notch. Your lower receiver needs an FA pocket or low shelf, and you should run an FA bolt carrier group. An H2 or H3 buffer weight is strongly recommended. Installation is a drop-in swap of your factory safety selector, though some fitment may be required and certain platforms such as AR9 variants may need professional gunsmithing.

Built from heat-treated steel

The selector is machined from heat-treated 4140 steel and given a corrosion-resistant finish, so it holds up to repeated cycling and field conditions like the rest of the AR-15 triggers at FRT Triggers USA. The 90-degree throw gives a crisp, positive engagement at each position, and the textured, chamfered lever lets your thumb find the selector quickly. Both ambidextrous and SEF single-sided versions are offered.
