Fixing Charging Handle Resistance & Slide Realignment

My charging handle is not cycling properly or is hard to charge during use. How do I fix this?

Check to see that the firearm is aligned so the top of the slide is parallel to the floor.
Ensure the firearm is fully engaged in the front of the chassis before closing the rear chassis gun door.

  • Step 1 (Check Accessory Rail): Check that the accessory rail of the firearm is fully engaged with the rail inside the chassis.

  • If you insert the firearm and miss the chassis rail, the firearm will not be aligned correctly.

  • Pull out the firearm and visually look into the chassis while inserting it to ensure the rail engages properly.

  • Step 2 (Check Beavertail): The beavertail of the firearm should fit snug with the beavertail surface of the gun door.

  • If it does not, the firearm will be misaligned.
