You can adjust an old Remington 700 trigger by first removing the screw that holds the safety in place. Once the safety is removed, you can then remove the trigger assembly by pulling it straight out.
To adjust the trigger, you’ll need a screwdriver to remove the screws that hold the sear and striker assembly in place. Once these screws are removed, you can then adjust the tension on each of these assemblies by turning the adjustment screws. Be careful not to over-tighten these screws, as this can damage the parts.
Once you’ve made your adjustments, reassemble the trigger assembly and replace the safety screw. Test your rifle to make sure that it fires correctly and reset any screws that have been moved too far.
