The trigger and sear engagement is the surface areas of the trigger and the sear that come in contact with one another when the rifle is in the cocked position. The surface area will determine the amount of trigger travel required to fire the rifle and will increase or reduce creep and crispness of the trigger pull. The sear engagement should be approximately .030 of an inch, (as viewed through the inspection hole on the trigger housing); but this measurement is not always the most accurate determination for the adjustment of the trigger engagement surfaces, because the matching surfaces have been hand stoned and may vary.
The best way to determine the proper engagement adjustment is to first loosen the two set screws holding the sear engagement screw (located at the rear ot the trigger assembly housing). With the rifle cocked, turn the screw clockwise until the sear drops past the trigger. Then turn the adjustment screw counterclockwise approximately one-half turn. This will result in approximately .030 of an inch engagement. At this point, snug the set screws, as described earlier, to hold the adjustment screw in place.
WARNING: INADEQUATE DEPTH OF ENGAGEMENT CAN CREATE AN UNSAFE SITUATION WHICH COULD CAUSE ACCIDENTAL DISCHARGE. IT IS VITALLY IMPORTANT TO ENSURE THAT THE SEAR AND TRIGGER ENGAGEMENT IS SUFFICIENT TO PREVENT ACCIDENTAL DISCHARGE IF THE RIFLE IS DROPPED.
To avert this potentially dangerous situation, perform the following check. Hold the barreled action by the barrel with the rifle cocked and the safety off. With a rearward motion, strike the tang of the rifle on something firm, but soft, such as a block of wood or rubber pad Repeat several times to ensure the rifle will not discharge under impact. If the rifle does not discharge the engagement is adequate. If the rifle does discharge, increase the engagement by turning the adjustment screw counterclockwise until the rifle will not discharge when impacted on the tang as described earlier. The standard factory setting is .030 inch. WE STRONGLY RECOMMEND THAT THIS ADJUSTMENT BE MADE ONLY BY AN EXPERIENCED GUNSMITH OR ARMORER.
