Atrius Forced Reset Selector (Single Side)

The Atrius Forced Reset Selector (Single Side) from Atrius Development Group replaces the standard safety selector in a compatible AR-pattern firearm. It does not replace the whole trigger or fire control group. It works with a compatible fire control group you already have.

The selector has three positions: SAFE, SEMI and Super-Semi. Super-Semi is the forced reset position. As the bolt carrier cycles, the selector returns the trigger to its ready position after each shot. The single side version has one selector lever, like a standard AR-15 safety selector.

Atrius designed the FRS as a drop-in part, but forced reset depends on the whole rifle working as one system. Plan on a compatible lower receiver and trigger pocket, a compatible fire control group, a full-profile bolt carrier group, proper gas delivery and a tuned buffer and spring. Most problems come from the parts around the selector, not the selector alone. Need a lower with room for it? One Horse AR-15 lowers are low shelf lowers that accept multiple forced reset style devices.
