The Timney 668S is a self-contained, drop-in trigger module for small-pin AR-15 lower receivers. It delivers a smooth, crisp single-stage pull with no creep, closer in feel to a bolt-action rifle than a standard mil-spec trigger. The pull weight is set at 4 lb, so no adjustment is needed after installation.
