Trigger Tech Duty AR-10 Single Stage Curved Rifle Trigger - The design of our new Duty Line was driven by feedback from military and law enforcement operators. They wanted our patented Zero Creep Technology and proven stainless steel internals, but with a more tactile feel. To achieve this, we more than doubled the pull weight and length of the first stage. The AR Duty line is the latest in TriggerTech triggers that offers robust reliability without compromising performance. Inspired by active MIL / LE Operators these triggers offer a longer take up (on two-stages) and a more forceful reset. Features Pull weight of 3.5 lbs; Curved Trigger; 440C Stainless Steel; Compatible with AR-10 platforms; Single Stage Trigger;
