This barrel set consists of a barrel with barrel shroud, a magazine in the matching caliber and the pellet probe.

Changing the barrel is extremely easy:

1. 1. Loosen the two locking screws on the top so the barrel comes free, and pull it out of the action.
   2. Unscrew the loading pin using the hole that runs through the pin. A thin Allen key works well for this.
   3. Fit the new loading pin.
   4. Lubricate the O-rings on the new barrel with a little silicone grease and insert it into the action.
   5. Tighten the locking screws.
