Action and Safety Systems
Rolling Block Action and Hammer Spur Safety
The rolling block action can be opened to install and remove primers.

The hammer spur safety provides protection from accidental discharge by changing the
shape of the hammer nose so as to allow or not allow contact with the firing pin. This
is achieved by pivoting the hammer spur downward to the safe position any time the
hammer is cocked or de-cocked. When the rear of the spur is pushed down the forward
portion of the hammer nose is rotated upward, preventing contact with the firing pin. For
the rifle to fire, the spur must be moved to the raised position before the trigger is pulled.

If for any reason the hammer spur does not pivot into either position with a positive
click, or fails to move to the down (safe) position any time the hammer is cocked or decocked,
immediately discontinue use of your rifle.

Trigger Blocking Cross Bolt Safety
This safety mechanism blocks the movement of the trigger to the rear (fire) position. This
safety bolt consists of a red plastic ring embedded in the bolt to indicate the position of
the safety. When the red ring is visible, the safety is off and when the trigger is pulled the
hammer will fall and a loaded gun will fire.

The trigger blocking cross bolt safety prevents firing of the rifle from
the cocked position only. Do not allow the hammer to rest on the firing pin with the
hammer spur safety in the up (fire) position when the rifle is primed! An accidental
discharge can occur from impact to the hammer or dropping the rifle even with the
trigger safety engaged. Never transport, carry, or handle your rifle in this condition.

Disassembly and Assembly

Be sure the muzzleloader is not loaded or primed before disassembly or
Study the rifle schematic and acquaint yourself with the different parts and terminology
of your muzzleloader before assembling or disassembling. Letters and numbers in parentheses
refer to labels on each rifle schematic for each model.
It is advisable to use a padded vise to remove and reinstall the breech plug. Place small
parts in a pan to avoid losing them.
1. Remove the trigger assembly. Press the release button located just behind the trigger
guard. Swing the action away from the rifle and pull it out of the receiver.
2. Remove the breech plug. Insert the combo tool (socket end first) into the receiver,
engage the plug (I) and turn it counterclockwise until it slides out of the receiver. This
may require more force. (A hole in the combo tool allows for the use of a rod, for
added leverage.) Put the plug in a jar of Knight solvent for a few minutes while cleaning
the barrel and receiver.

3. Remove the forearm stock. By using the screwdriver end of the combo tool, take out
the stock screw (S9) located on the underside of the stock. The stock and barrel easily
4. Remove the barrel. Using the socket end of the combo tool, take out the bolt (S6)
that is located in the forearm stock chamber. Unscrew it counter clockwise, until it
slides out of the receiver. Pull the barrel up and out to release it from the receiver.
1. Install the breech plug. Fill the threads of the plug with Knight Breech Plug Grease to
help prevent the breach plug from sticking in the receiver. Using the breech plug end
of the combo tool, insert the breech plug (I) into the rear of the receiver and handtighten
the plug into the receiver until it is firmly against the back of the barrel. Be
sure the breech plug is screwed all the way into the receiver. Do not over tighten the
plug or it will become difficult to remove.
2. Install the trigger assembly.
3. Install the barrel and stock. Replace the stock screw (S9) and bolt (S6.).
