Browning x-bolt rifle adjusting?

Martin Mapa Answered question September 7, 2022

The first step necessary to replace the X-Bolt trigger spring is to remove the trigger assembly from the receiver. Do this by driving out the 2 pins seen at the top of the trigger housing. These pins have serrations on the ends. Therefore, they must be driven out from the other side.

The punch is shown driving out the front trigger housing retaining pin. Drive both the front and the rear pin out from this side.

When X-Bolt trigger assembly is sufficiently disassembled to replace the trigger weight of the pull spring.

After removing the trigger assembly from the receiver, remove the sear and the cone-shaped sear spring, by driving out the sear pivot pin. This pin is just in front of the safety button.

Near the center of the trigger housing, you will see the actuator pivot pin. Drive this pin out just far enough to release the actuator, but not all the way out of the trigger housing. Now it will be necessary to move the actuator slightly to the rear and down so that better access to the trigger spring can be had. After making this move, a small part of the actuator can be seen protruding from the bottom of the trigger housing, just in front of the trigger.

The new spring is pointing at the hole in the housing through which it must be inserted. The lower end of the spring must fit down into the housings spring pocket, which is located directly above the Allen head weight of the pull adjusting screw.

Complete the installation of the spring by moving the actuator back into its original position, above the upper end of the newly installed trigger spring, and with its pivot hole aligned with the pivot pin. Tap the pivot pin back into place, and install the weight of pull adjusting screw. Verify that the actuator is now powered by the trigger spring and moves smoothly.

Trigger assembly being installed on receiver, Tap trigger assembly retaining pins in from this side, with the serrated end of pin up. With the rifle assembled, but un-loaded, check for reliable function of the trigger, the safety, and the bolt lock.


There are a few things that could be causing your trigger to feel “heavy”. It’s possible that the bolt is not seating all the way forward into the battery, which would put extra tension on the trigger. You can try gently tapping the butt of the rifle on a solid surface to ensure that the bolt is fully seated.

It’s also possible that you have too much gun oil or grease on your firing pin, which can create friction and make it harder for the trigger to move. Try cleaning off as much of the oil or grease as you can, and then see if it feels better. If it doesn’t, you may need to have a gunsmith take a look at it to see if there’s anything else that can be done.
