Atrius FRS by BothanSpy, Verified Owner, April 12, 2026
Had to use a Dremel on the trigger tail and polish a bit but I got it running smooth. You gotta use a H2 or higher buffer weight. Lots of videos on how to get it running so please do some research, especially if you have never built an AR. It's reall...

Product Info for Atrius Development Forced Reset Selector

The Atrius Forced Reset Selector, also known as the Atrius Super Selektor, upgrades your AR-15 safety selector to provide three firing modes: Safety, Semi (standard single shot), and Full-Semi. This third firing mode allows these Rifle Parts to interact with your trigger group, quickly resetting your trigger to allow for faster engagement and follow-up shots. The Atrius Development Super Selector is an excellent alternative to the Forced Reset FRT trigger as it greatly reduces wear on your rifle. Drop-in installation allows you to swiftly swap your safety in minutes with an extremely durable FRS that performs in the harshest conditions.image

The Atrius Super Selector is compatible with Mil-Spec AR-15s chambered in .223, 5.56, or .300 BLK and doesn’t require any other modifications. With incredibly smooth engagement and aggressive ergonomics, manipulating your AR-15 safety has never been easier. Upgrade your AR today to greatly increase your trigger pulls and deliver faster shots on target.
