The new Timney 2-Stage trigger is the latest model in that series. The pull weight is factory calibrated for a eight-ounce first stage and one -pound second stage (the second stage is adjustable from 8-ounces to 2.5-pounds of pull weight) The 2-Stage trigger features machined and hardened steel work surfaces milled from A2 tool steel and all three sears are Teflon-nickel coated for added lubricity. The trigger housing and shoe are CNC machined using state-of-the-art robotics and the sears are EDM cut from high-grade solid steel. The trigger housing utilizes an anodized aluminum body and the trigger shoe and safety are carbonitrided which dramatically increases the surface hardness and wear-resistance properties of the metal. The Timney 2 Stage Straight Trigger is easily installed with no screws, drilling, or tapping required. By simply removing existing pins, replacing trigger, and inserting existing pins anyone can replace a trigger on their Remington 700. The Timney Calvin Elite Series Triggers now feature Carbo Nitride Coating, which allows us the opportunity to provide you with the highest quality trigger available anywhere. The thermochemical process simultaneously diffuses nitrogen and carbon into the surface of ferrous metals. This coating is substantially harder than hardened tool steel and increases the long-term wear, provides exceptional corrosion resistance, far surpassing the military salt water corrosion standards and increases lubricity to your trigger. This provides your Timney with a lifetime of smooth edges because we understand the importance of, Every shot counts. The Calvin Elite Series of triggers are named for Calvin Motley, Timney s design genius, who is responsible for such award-winning triggers as the Timney AR drop-in trigger, Remington 700 with unique trigger blocking safety and loads of other critically acclaimed replacement triggers.
