How-to | Remove the breach from the Stormrider, Chaser, or Bandit

You may need to remove the barrel assembly to switch receivers or repair the bolt or handle on your Diana air gun.  Use this how-to guide to remove the old breech and bolt-probe.

1. Start by loosening the barrel band.
2. After you loosen the barrel band, remove the three screws from the front of the breach and pull the barrel out.
3. Remove the stock or grip.
4. Remove the small screw in the top of the breech where the single shot tray/magazine would sit.
5. Remove the second screw holding the breach to the lower tube, located underneath the rear of the tube.
6. You can now lift the receiver off of the lower tube.
7. Underneath the receiver, locate the cocking screw that protrudes from the bolt probe - remove that screw.
8. Un-thread the bolt handle from the bolt probe.
9. Pull the bolt probe from the breach.

Reverse the process to re-install the replacement breach. 

When mounting the breach into the lower tube, make sure the cocking screw from step 5 is in front of the tube's striker screw (the bolt handle must be fully forward).
