Trigger Housing For Tc Thunderhawk

Make sure that the firearm you are working with is uncharged and unprimed prior to making any trigger adjustments. FAILURE TO HEED THIS WARNING COULD RESULT IN ACCIDENTAL DISCHARGE WHICH MAY CAUSE INJURY AND/OR DEATH TO THE SHOOTER OR BYSTANDERS AND DAMAGE TO PROPERTY.

Adjustment of the ThunderHawk trigger requires that the receiver/barrel be removed from the stock. To do this, follow the takedown instructions found in the assembly and disassembly section of this manual.

Important: The ThunderHawk should not be dry fired without a nipple protector. To avoid damage to the nipple caused by the striker contacting it, install a 3/8" long piece of rubber hose over the nipple.

Important: Any adjustment to the sear engagement adjustment screw (Screw "1" in the diagram on page 27) should always be made first. Only after this adjustment is made should the shooter adjust the over-travel screw (Screw "2" in the diagram on the page 27).

TO LESSEN THE AMOUNT OF SEAR ENGAGEMENT, FOLLOW THESE INSTRUCTIONS:

Step 1. Ensure that the striker handle is in the "Fire" position and that there is a nipple protector in place on the nipple.

Step 2. Loosen the 1/4" lock nut on Screw #1 (See diagram on page 27) by turning it counter-clockwise as viewed from the rear of the trigger housing.

Step 3. Using a .050" hex wrench, turn Screw #1 clockwise slowly until the striker handle falls forward to the "Fired" position (keeping fingers clear of the striker and striker handle as it falls).

Step 4. Turn the .050" hex wrench one-third (1/3) turn counterclockwise. THIS IS THE ABSOLUTE MINIMUM SETTING FOR SEAR ENGAGEMENT.

Step 5. Return the receiver/barrel assembly into the stock. Draw the striker handle rearward into the "Cocked" position. Shoulder the rifle and dry fire it to check the "feel" of this adjustment. If this adjustment is satisfactory remove the receiver/barrel assembly from the stock.

Step 6. After sear engagement adjustment is finalized, retighten the 1/4" lock nut, making sure that sear engagement adjustment screw (Screw #1) remains in the same position.

Step 7. Reassemble the rifle.

To increase sear engagement from this minimum setting, , the .050" hex screw (Screw "A") should be turned counterclockwise further than the one third minimum turn stated above.

Trigger adjustment for Over-travel (Screw "B" in diagram on page 29)

TO LESSEN THE AMOUNT OF TRIGGER OVER-TRAVEL, FOLLOW THESE INSTRUCTIONS:

Step 1. Ensure that the striker handle is in the "Fire" position and that there is a nipple protector in place on the nipple.

Step 2. Loosen the 1/4" lock nut on Screw #2 (See page 27) by turning it counterclockwise as viewed from the front of the trigger housing.

Step 3. Turn the hex screw #2 with a .050" allen wrench clockwise until it meets resistance (stops). Then, while holding the trigger back, turn the screw counter clockwise until the striker falls to the "fired" position. Back the screw up (counterclockwise) from this position one-quarter (1/4) turn. THIS IS THE MINIMUM SETTING FOR OVER-TRAVEL. Retighten the lock nut.

Step 4. Return the receiver/barrel assembly into the stock. Draw the striker handle rearward into the "Fire" position. Shoulder the rifle and dry fire it to check the "feel" of this adjustment. If this adjustment is satisfactory remove the receiver/barrel assembly from the stock.

Step 5. After the over-travel adjustment is finalized, retighten the 1/4" lock nut, making sure that the over-travel adjustment screw (Screw #2) remains in the same position.

Step 6. Reassemble the rifle.

To increase trigger over-travel, the .050" hex screw (Screw #2) should be turned counterclockwise further than the one quarter minimum turn.
