A drop-in trigger module replaces the standard mil-spec trigger group components — trigger, hammer, disconnector, and springs — with a self-contained unit that installs directly in the standard trigger and hammer pin holes of any mil-spec AR-15 lower receiver without modification. The drop-in design eliminates the need to individually fit and time trigger components, making installation consistent and repeatable regardless of lower receiver manufacturer. The RA-140 SST is designed for competitive shooting and precision applications where a light, clean trigger pull is critical to performance. The short reset allows the shooter to release the trigger only far enough to reset before the next shot, enabling faster follow-up shots during rapid fire stages. Verify local regulations and intended application before installing a reduced-weight trigger — very light pull weights may not be appropriate for all defensive or duty uses.
