1. The internal set screw comes with thread locker pre-applied but for
best results remove the internal screw and apply additional thread
locker and re install the set screw inside the large screw. Make sure
to screw down the internal screw all the way in so that the tip just
protrudes.

Remove the factory grip screw and lock washer from the grip of your
rifle. Mind the spring and detent for the safety as they may bounce out
if you remove the grip completely.
3. With the hammer cocked and
the gun on safe, insert the Trigger Adjustment Screw into the grip and
tighten the large screw with a 3/16” hex wrench until he pistol grip is
secure.
4. Using the included hex wrench, finger tighten the
internal screw inside the 3/16” screw until the it stops. DO NOT OVER
TIGHTEN. Backout the internal screw 1/4 turn at a time until the
safety lever can by actuated. Verify that the trigger, disconnector,
hammer and safety function correctly. Let your additional thread locker
dry before putting your rifle to use.
