14 STAINLESS STEEL COMPONENTS The trigger housing and all internal components of the M.O.A. Trigger System are constructed of durable, corrosion-resistant stainless steel. Trigger Piece Actuator Sear Trigger Housing 1 READY POSITION Take-Up Spring Overtravel Adj. Screw Pull Weight Adj. Screw Sear Return Spring 2 RELEASED POSITION 2X X C A B C A B ZERO TAKE-UP Take-up is the distance the trigger piece travels prior to the sear moving toward release and the shooter feeling resistance. The M.O.A. Trigger System uses a spring to eliminate take-up by keeping the trigger piece in constant contact with the actuator. Unlike competitors’ designs, the unique geometry of the M.O.A. pre-loads the entire trigger system to bias out normal manufacturing tolerances. ZERO CREEP Creep is the perceptible movement of the trigger prior to the release of the firing pin and has a negative influence on accuracy, causing inconsistency and uncertainty during the pull of the trigger. Creep contributes to jerking the trigger, thus adding to movement of the gun during firing. The 2:1 mechanical advantage created by the M.O.A. Trigger’s unique design geometry has virtually eliminated creep in the Model 70®. ZERO OVERTRAVEL Overtravel is the rearward movement of the trigger after the firing pin has been released. It can actually jar the gun away from its intended point of aim and is very distracting to the shooter. The M.O.A. Trigger System on the Model 70® is set at the factory to have no perceptible overtravel. When the sear drops, the trigger stops. Where you aim is where you shoot. (1) M.O.A. TRIGGER SYSTEM The M.O.A. Trigger System featured on the Model 70® works on the simple principle of the pivoting lever. Pictured above are the trigger piece (A), actuator (B), and sear (C). The housing and all internal parts, pins and springs are precision crafted from stainless steel. In addition, an electroless Nickel Teflon™ coating is on the sear and actuator for added corrosion resistance and smoother operation. (2) 2:1 MECHANICAL ADVANTAGE The M.O.A.’s trigger piece offers a wide, smooth face to better distribute finger pressure for a lighter, more sensitive feel. Because of its geometry and 2:1 mechanical advantage, the trigger piece travels only half the distance of the actuator (2X). Since this distance is cut in half, the perception of creep and overtravel are virtually eliminated.
