Timney Trigger Calvin Elite Trigger Features The Timney Triggers Calvin Elite Trigger is a drop-in replacement for the AR platform that pairs a 5-pound hammer spring with a factory set 1.5-pound trigger pull for a crisp zero creep break. Quick reset lets shooters follow up fast strings of fire without waiting on the trigger to fully travel forward again. The wear components are built from A2 tool steel heat treated to Rockwell 58 and finished in Teflon-nickel a combination chosen for long-term durability under heavy round counts. Sear engagement pull weight and overtravel are all adjustable letting the shooter fine tune the feel to their own preference rather than accepting a fixed factory setting. The trigger housing is CNC machined from lightweight 6061-T6 aluminum and anodized in Timney s Elite Gold finish giving it a distinct look along with corrosion resistance. Four interchangeable trigger shoes curved flat heeled and knurled ship with the unit so shooters can match the shoe shape to their grip and shooting style. This small pin design fits most AR-15 rifles using the standard .156 inch Mil-Spec trigger pin covering the vast majority of the AR platform. For AR shooters seeking a precision fully adjustable trigger with real finish and material quality the Timney Calvin Elite is available for sale at GrabAGun.
