Charging Handle Disassembly / Changing Config
Step 1: Remove your X01 upper module.
1A // Remove the magazine and clear the weapon.
1B // Lock the slide to the rear via the slide stop.
1C // Slide the arm brace to its outermost setting (if applicable).
1D // Open the X01 by depressing the receiver latch in the rear and hingeing open.
1E // Remove the receiver pin at the front of the X01 by depressing the detent.
Step 2: Disassemble the charging handle.
2A // Unscrew and remove the charging handle retention screw with a 2.5mm allen key.
2B // With your thumb on the charging handle forks, press the charging handle carrier nearly all the way to the rear until the charging handle arms are aligned with the largest opening in the charging handle slots.
2C // Remove the charging handle with the straight arm (the side that is on the left when firing) first by sliding it in a perpendicular direction to the bore axis. Also remove the opposite side charging handle in the same manner as shown above.
2D // With the charging handles removed, carefully release the charging handle carrier from its spring tension and allow it to slide forward. Remove it from the assembly.
2E // Remove the charging handle spring and rear latch pin by sliding them forward and out of the X01 upper module. At this point the guide rods can be unthreaded from the carrier and rear latch.
Step 3: Reverse the charging handle forks (if applicable)
3A // Place the charging handle carrier in a vice so that the upper (thinner) area is in the vice and the lower (wider) area is not blocked on either side.
3B // Using a hammer and a punch, flat head screwdriver, or pistol sight removal tool gently tap the charging handle forks directly on the dovetail to either side until they are removed from the carrier.
3C // Reverse the orientation of the forks and re-install into the carrier by tapping them into place.
Step 4: Reinstalling the charging handle assembly
4A // Place the rear latch and rod into the X01 upper module by sliding it into place.
4B // Slide the charging handle spring over the rear latch rod.
4C // Install the charging handle carrier and tube by sliding it into place, being sure that both the rear latch rod and carrier tube mate properly. Note: images below show the assembly outside of the X01 upper module for illustration purposes.
4D // With your thumb on the charging handle forks, press the charging handle carrier nearly all the way to the rear until the gap in the charging handle carrier is aligned with the largest opening in the charging handle slots.
4E // Insert the z-shaped charging handle first and seat it in the charging handle carrier.
4F // Insert the straight-armed charging handle next and seat it in the charging handle carrier.
4G // Release the charging handle carrier so that it slides all the way to the front of its track.
4H // Reinstall the charging handle retention screw.
Step 5: Reinstalling the X01 upper module into the weapon.
5A // Lock your slide to the rear with the slide stop.
5B // Align the X01 upper module with the front hinge hole and reinsert the latch hinge pin.
5C // Close the upper module and sure the rear latch is engaged.
5D // Rack the charging handle all the way to the rear to release the slide. Perform a functions check to ensure your X01 is now operational.
