The Geissele Super 3 Gun (S3G) Curved AR-15 Trigger is a rapid, hybrid single-stage trigger engineered for ultra-fast splits and aggressive competition use. It features a very short, light take-up and a hard, quick break with an equally fast reset. Works with mil-spec AR-15 lower receivers (0.154″ pins), safety selector, hammer/disconnector interfaces, and standard springs. Fully compatible with AR-15 uppers/BCGs and buffer systems. Ideal for 3-Gun and dynamic shooting where speed is paramount.
