In order to produce the perfect tube for your barrel, 2 measurements are required: Exact barrel diameter at the muzzle, and exact barrel length.
To determine your exact barrel measurements please follow the following procedure:
MEASURING
Exact barrel length & diameter
- Make sure your rifle is safe.
- Insert an empty shell to the chamber and close the bolt.
- Insert a cleaning rod from the muzzle end until it stops.
- Mark the rod right at the muzzle.
- Take the rod out and measure it from the end till the mark.
- That’s your exact barrel length.
