How to adjust Remington 700 Xmark trigger?

1. Make sure the gun is unloaded! Remove the stock; this is very important because you can’t adjust the trigger with the stock in place.
2. Place the cap on top of the bolt and flip it over so that the trigger is facing up. The trigger’s adjustment screw is in the middle of the trigger assembly, just behind where you grip the gun. There is only one adjustment screw, and it’s a 1/16″ Allen key.
3. Clean any epoxy or other materials that may be preventing the screw from coming out.
4. To reduce the trigger pull, turn the screw counterclockwise. Turn the screw clockwise to boost the pull weight. It would be beneficial to keep track of how many turns you made so that if you want to return to the previous pull weight, it is simple to do so. My trigger pull was reduced by roughly 4 pounds 2 ounces (counterclockwise). Note: If the trigger pull is too light, the bolt will not cock; therefore, increase it (clockwise) by approximately 1/4 turn at a time until the bolt cocks.
5. To avoid your gun slam-firing, follow these steps. First, clear the gun of ammo and snap the bolt closed as forcefully as possible. Second, cycle through the safety a few times. If a dried fire doesn’t occur and everything appears fine, you’re all set!
6. To finish, back the trigger adjustment screw out 2 full turns (counter-clockwise), and clean the screw and trigger assembly front with acetone or another degreaser. Apply blue Loc-Tite or other removable thread-locker to the screw a very scarce amount. Then retighten the screw 2 times, and remove any excess.
7. Test the bolt for slam fires again. Put the stock back on, and drop the rifle from about 6 or 7 inches a couple of times to make sure it won’t slam-fire again. If not, you’re all set! Congratulations!
