The Timney AR-15 Small Pin Trigger, 4lb, Solid (brand part no. 668S) is a solid, non-adjustable trigger built for standard AR-15 lowers using the mil-spec small trigger pin. It breaks at a fixed 4-pound pull weight, giving shooters a slightly heavier option than Timney’s 3-pound small-pin trigger for those who prefer more margin in a duty or hunting rifle. For AR-15 owners who want a straightforward, fixed-weight upgrade over the factory trigger, this AR trigger is a simple, solid-shoe option.
