Remington 700 trigger adjustment
The three adjustments are:
1) The trigger stop (over travel).
2) The trigger weight (pull).
3) The sear engagement.
On the front side of the trigger mechanism are two screws held in place with an epoxy coating. The top screw, nearest the barrel, is the Trigger Stop Screw. The bottom screw, furthest from the barrel, is the Trigger Weight Screw.
Remove the epoxy coating from the screws.
First set the trigger stop. Turn the Trigger Stop Screw IN 1/4 of a turn at a time. After each 1/4 turn, try the trigger. Keep doing this until the trigger will not fall. Then back the screw OUT 1/8 turn at a time until the trigger will fall again. Add 1/8 more turn OUT.
Next, set the trigger weight. Back the bottom screw OUT 1/8 turn at a time; test the trigger after each adjustment, until you're happy with the weight of pull.
Sear engagement is an optional step; there is usually very little or no creep from the factory. Proper Sear Engagement Is Critical To Safety! Make only very minor adjustments at a time. I have found that 1/32 of a turn makes a major difference. Back the screw out for less engagement.
Test for potential misfiring by pounding the butt of the rifle against the floor with the barreled action installed and the firing mechanism cocked.
Finally, give the screws and front edge of the mechanism two coats of nail polish to keep the screws from loosening.
