Copied word for word from the owners manual...

Adjusting Trigger Pull Weight

1. Open the bolt and ensure the rifle is completely
unloaded. Remove the bolt as explained on page 14.

2. Remove the two action screws with a 5/32" Allen
wrench (Figure 17).

3. Lift the bottom metal from the stock (Figure 18). It is
not necessary to remove the magazine box, however,
note its orientation should it come out of the rifle.

4. Carefully lift the barreled action out of the stock
(Figure 19).

5. There are two screws in front of the trigger housing.
The screw that is furthest from the action can be
turned to adjust trigger pull weight, and the screw
that is closest to the action can be turned to adjust
overtravel (Figure 20).

6. To decrease the trigger pull weight, turn the
adjustment screw that is furthest from the action in a
counterclockwise direction using a 1/16" Allen wrench.

Notice ! The trigger pull weight screw will fall
out when the trigger has been adjusted to its
minimum pull weight of 3 pounds.


7. To increase the trigger pull weight, turn the
adjustment screw that is furthest from the action in
a clockwise direction using a 1/16" Allen wrench.

Notice ! do not turn the trigger pull weight
screw in too far. Doing so will limit the trigger
travel, rendering the trigger inoperative, and
could damage the pull weight spring.


8. Trigger pull weight can be measured, with the rifle
completely unloaded and the bolt closed, using a very
accurate spring scale or a commercially available set of
trigger pull measuring weights. Most gunsmiths can
also measure trigger pull for you.

Notice ! If trigger pull weight is increased
too much, the trigger cannot be pulled. Turn the
screw counterclock wise until trigger
can be pulled.


9. When finished making the adjustment, place a drop
of serviceable thread locker on the adjustment screw.

10. Place the barreled action back in the stock and
reinstall the magazine box (if necessary) and bottom
metal. Torque the two action screws to 35 inch pounds.

Adjusting Trigger Overtravel

Overtravel is the amount the trigger moves after the
firing pin has been released by the sear. It should not
be necessary to adjust overtravel on your Model 70.
However, should overtravel require adjustment, perform
the following procedure:


1. Open the bolt and ensure the rifle is completely
unloaded.

2. Remove the two action screws with a 5/32" Allen
wrench (Figure 17).

3. Lift the bottom metal from the stock (Figure 18).

4. Carefully lift the barreled action out of the stock
(Figure 19).

5. There are two screws in front of the trigger housing.
The screw that is furthest from the action can be
turned to adjust trigger pull weight, and the screw
that is closest to the action can be turned to adjust
overtravel (Figure 20).
To increase the amount of overtravel, turn the
adjustment screw closest to the action in a
counterclockwise direction using a 1/16" Allen wrench.
To decrease the amount of overtravel, turn the
adjustment screw closest to the action in a clockwise
direction using a 1/16" Allen wrench.

Notice ! If the overtravel screw is turned in
too far, the trigger cannot be pulled far
enough to release the sear and fire the rifle.
Turn the screw counterclock wise until the
trigger can be pulled.


6. When finished making the adjustment, place a drop
of serviceable thread locker on the adjustment screw.

7. Place the barreled action back in the stock and
reinstall the magazine box (if necessary) and bottom
metal. Torque the two action screws to 35 inch pounds.

I have a 308 FW with the MOA trigger. It's advertised as having a pull weight of ~3.5 pounds and adjustability from 3-5 pounds.

The pull weight measures 6 lbs 1oz average over 20 pulls. That isn't acceptable to me.

I've attempted to adjust the trigger following the instructions in the owners manual, but the 1/16" Allen adjustment screws for pull weight and overtravel are covered in a really tough epoxy. I was able to scrape most of it off but I can't get it out from inside the hexes of the tiny Allen screws.

I've been told my only option is to pay a gunsmith for a trigger job. I'm not going to do that for an expensive rifle that is advertised as having an adjustable trigger.

Anyone have any suggestions?

Tac, I was able to get the gunk off the screws by the rather tedious use of dental picks and Goof Off. It was worth the effort in my opinion. Good luck.

Had same problem, tkle a butane lighter and heat the end of the allen wrench, will melt the epoxy. Took several tries on mine before I got enough out to be able to move the screw. At about 3 pounds the screw will still back out but trigger pull doesn't seem to get any lighter. Thread locker is recommended as the screw has almost no tension once it is free to move

Well I was able to get the glue out of the adjustment screw & fiddled around with it for a while. I'll have to wait til I can borrow a trigger pull scale again, but even with the screw all the way out the trigger still feels too heavy. That is, I can hold the barreled action (~5+ lbs with scope) by the trigger, and it won't trip the sear unless I help it. I'll have to see what the scale says, but it seems that the adjustment did nothing. I double checked that I had the right screw ( the one closest to the trigger/furthest from the action). Anyone have ideas on that?

Thanks again for the help!
