The Izhmash Biathlon 7-3 Bolt Action Rifle will be used as an example for cleaning. Removal of the action is specific for every firearm model, but the general cleaning procedures remain the same.
Field-Stripping consists of removing the main component of the firearm, in other words, the action. Field-Stripping a firearm for cleaning should be done on a regular basis, before firing a weapon that has not been used for a long time, and subsequent to every 500 rounds fired.
1. Ensure that the firearm is unloaded.
2. Remove the Bolt.
3. Clean rifle using patches cut to fit the rifle's bore. Use patches in the following order:
I. Dry patch or patch with Nitro Solvent (to remove any residue and carbon build-up); until the patch runs through and no longer appears to be soiled.
II. Oiled patch (to lubricate desired area); once or twice.
III. Dry patch (to remove any excess oil); until the patch is dry after being run through.
4. Clean the bolt with patches, paying particular attention to the face, extractor, and ejector.
5. Insert patches in the appropriate order (see step 3) with a cleaning rod down the bore to clean it. Note: always clean the bore from the breech to the muzzle.
6. [OPTIONAL] Clean the chamber with an old toothbrush or dentist tool. Do not use sharp objects (eg: dentist tools) in the bore; clean only around the bore where the extractor and bolt face rests when the bolt is closed.
7. Reassemble firearm.
8. Pour a drop or two of gun oil onto the closed bolt and cycle (open and close bolt) a few times to lubricate the entire bolt area.
9. Lubricate other metal surfaces of the firearm with a patch, wiping off any excess oil.
HAPPY SHOOTING!
