DISASSEMBLY FOR CLEANING
WARNING: ALWAYS KEEP THE MUZZLE POINTED IN A SAFE DIRECTION.
WARNING: NEVER ATTEMPT TO CLEAN OR DISASSEMBLE A CHARGED OR PRIMED MUZZLELOADING FIREARM. AN ACCIDENtAL DISCHARGE CAN CAUSE IN JURY AND/OR DEATH TO THE SHOOTER OR BY STANDERS AND DAMAGE TO PROPERTY.
WARNING: WEAR SAFETY GLASSES EVERY TIME YOU ASSEMBLE OR DISASSEMBLE YOUR FIREARM.
• NEVER DISASSEMBLE YOUR FIREARM beyond the procedures outlined in this manual. Improper disassembly or re-assembly of your firearm may be dangerous and can lead to serious injury or death.
To disassemble the Hawken™ muzzleloading rifle;
• Remove the ramrod - set it aside.
• Pull out the wedge pin. It may be necessary to tap it partially out from the other side in order to grasp the pin and pull it the rest of the way out.
• Lift the barrel up as shown (Figure 35) and pull it forward away from the lock assembly. Pull the barrel forward, thus pulling the breech plug out of the breech plug slot in the tang.
• Next in the cleaning process; fill a pan with hot soapy water. Submerge the muzzle end of the barrel in the water and push a wet patch down the barrel (from the breech end) on the end of your ramrod with a jag in stalled. Pump the ramrod and patch up and down in the barrel. This will draw water into the bar rel and flush out the fouling. When the barrel is clean - allow it to dry.
