Timney AR-15 Large Pin Trigger, 3lb, Pre-2005 Colt

The Timney AR-15 Large Pin Trigger, 3lb, Pre-2005 Colt (brand part no. 667L) is a solid, non-adjustable trigger built specifically for older Colt AR-15 rifles made before 2005, which use a large-diameter .168 to .174-inch trigger pin rather than the .156-inch small pin found on most modern AR-15s. It is a 100% true drop-in trigger with no adjustments necessary and no pin rotation, breaking at a fixed 3-pound pull weight. Built from all-steel construction, it installs directly without gunsmithing. For owners of an original pre-2005 Colt AR-15 with a large-pin lower, this AR-15 trigger is matched to that older pin diameter.
