Corresponding figure, see Fig. 18.
Procedure:
1. Insert the barrel 400 from below up to the stop
into the clamping device. Ensure that the
barrel is aligned in such a way that the insert
remains easy to move all the time.
2. Place insert 308 from below up to the stop into
the receiver.
3. Turn the barrel until the insert engages in the
barrel groove.
4. Install clamping screw 306a.
5. Lightly tighten clamping screws 306, 306a.
6. Install and close the bolt (see section 5.7.3).
7. Check the bolt action with the gun unloaded.

fixed without tension (alternative: tightening
with a torque spanner: torque 7-8 Nm).
