INSTALLATION

The KID Match Trigger assembly is tuned and adjusted at the factory for optimum performance.

It is recommended that only standard and high velocity ammunition be used with the KID Match Trigger assembly.

To install the KID Match Trigger assembly:

1. First make sure your rifle is unloaded and pointed in a safe direction.
2. Remove the barreled action from the stock.
3. With the bolt forward, extract the two retaining pins and remove the existing trigger assembly.
4. Place the cocked KID trigger assembly into position in the action and insert the retaining pins.
5. Install the barreled action into the stock.

The KID Match Trigger assembly is now ready for service.

SAFETY

The safety button (106) is located at the front of the trigger guard. Depression of the safety button on the left side of the trigger guard locks the trigger and sear rendering the trigger assembly safe for carry or transport. Depressing the safety button on the right side will expose a red ring. This signifies that the safety has been released and the trigger assembly is ready to fire.

CAUTION! It is advised that you never transport a loaded weapon. See the included RULES FOR SAFE FIREARM HANDLING. If you have questions regarding the safe handling or operation of the KID Match Trigger, contact

OPERATION

The KID Match Trigger is a two-stage semi-automatic trigger assembly. As the trigger is pulled, it travels in a smooth rearward arc. This travel is called ‘slack’. Slack is the engagement of the hammer (122) and sear (128), which establishes the first stage. The slack is interrupted by the second stage pressure piece. This interruption establishes the ‘let off engagement’. The let off engagement is the point where slack (engagement) has been reduced to a minimum just prior to releasing the hammer. When sufficient pressure is placed on the second stage pressure piece, the hammer will be released, firing the rifle and cycling the action. Releasing the trigger (110) resets the assembly and allows it to be fired again.

NOTE: Never dry fire the KID Match Trigger when it is not installed in the Ruger 10/22 tm rifle. Dry firing without proper support for the hammer can cause damage to the assembly.

BOLT HOLD OPEN

The bolt hold open (152) is located in the forward section of the trigger guard. The bolt hold open manually retains the bolt in the rearward position.

To hold the bolt open, pull the bolt handle to the rear most point while depressing the lower portion of the bolt hold open. Slowly release the bolt handle until the bolt catches on the bolt hold open. To release the bolt hold open, pull the bolt handle to its rear most position and release. The bolt will move forward into battery.

CAUTION! The bolt hold open does not lock the bolt on the KID trigger assemblies. Retracting the bolt will release the bolt hold open and allow the bolt to move forward into battery. This is to facilitate loading in match situations and is not recommended for field use. It is recommended that the safety be in the ‘ON’ position at all times when the bolt is held open.

MAGAZINE LATCH

The magazine latch (153) is located at the foremost area of the trigger guard. When depressed the magazine latch releases the magazine for removal. When loading or unloading the magazine in the rifle, the bolt should always be locked open and the safety should be in the ‘ON’ position.

SLACK (FIRST STAGE)

The slack travel and weight are preset at the factory for optimum performance and should only be adjusted by a knowledgeable gunsmith.  Turning the hex screw in the center of the first stage pressure piece clockwise will increase the first stage pressure.  Turning the hex screw counter clockwise will decrease the first stage pressure.  Caution must be taken when decreasing first stage pressure as the sear is operated by this plunger and too little pressure will render the sear inoperable. 

LET OFF ENGAGEMENT (SECOND STAGE ENGAGEMENT)

Let off engagement is the point where slack has been reduced to a minimum just prior to releasing the hammer (122). This engagement is determined by the second stage pressure piece (134).

To increase let off:

1. Loosen the second stage pressure piece lock screw (150),
2. With a blade screwdriver, turn the second stage pressure piece clockwise. This will establish creep and should only be adjusted in ‘1/8’ turn increments.
3. Tighten the second stage pressure piece lock screw.

To decrease let off:

1. Loosen the second stage pressure piece lock screw,
2. With a blade screwdriver, turn the second stage pressure piece counter-clockwise. This will eliminate creep and should only be adjusted in ‘1/8’ turn increments. Too much counter-clockwise adjustment will eliminate second stage let off completely.
3. Tighten the second stage pressure piece lock screw.

Great care should be taken in this adjustment, and should only be performed by KID or a qualified gunsmith.

LET OFF PRESSURE (SECOND STAGE WEIGHT)

Let off pressure is the pressure required to release the hammer (122) from the sear (128) in turn firing the rifle. This pressure is determined by the second stage pressure piece (134). Turning the hex screw in the center of the second stage pressure piece clockwise will increase let off pressure. Turning the hex screw counter-clockwise will decrease let off pressure. Adjustments should be made in ‘1/4’ turn increments until the desired pressure is achieved. The let off pressure has been preset at the factory for optimum performance and should only be adjusted by KID or a qualified gunsmith.

OVER-TRAVEL

Over-travel is the rearward travel of the trigger (110) past the point of let off. This travel is determined by the over-travel screw (108).

To increase over-travel:

Turn the over-travel screw counter-clockwise. Adjustments should be made in ‘1/8’ turn increments until the desired over-travel is achieved.

To decrease over-travel:

Turn the over-travel screw clockwise. Adjustments should be made in ‘1/8’ turn increments until the desired over-travel is achieved.

The over-travel is preset at the factory for optimum performance and should only be adjusted by KID or a qualified gunsmith.

TRIGGER BODY POSITIONING SCREW

The trigger body positioning screw (116) determines the position of the trigger body and its relationship to the safety. Turning the trigger body positioning screw clockwise will move the trigger body rearward. Turning the trigger body positioning screw counter-clockwise will move the trigger body forward.

CAUTION! If the trigger body is positioned too far rearward, it may interfere with the operation of the safety button, causing a dangerous situation. This screw is preset at the factory for optimum performance and NO ADJUSTMENTS OR MODIFICATIONS SHOULD BE ATTEMPTED.

TAKE UP AND SEAR POSITION

Take up is the play between the trigger bar (124) and the sear connecting pin (130). The trigger bar must have a bit of take up in order to operate properly. The sear (128) position is determined by the sear positioning screw (151). This screw is used to position the sear in relation to the trigger bar.

Should the take up ever need adjustment, use the following instructions. With the trigger assembly out of the rifle, depress the hammer (122) until the trigger bar disconnects from the sear connecting pin. With the hammer still depressed, pull the trigger (110) to the rear. Release the hammer to the cocked position. Slowly release the trigger and note the action of the trigger bar. As the trigger reaches its foremost point, the trigger bar should rise and connect with the sear connecting pin. If the trigger bar fails to rise and connect with the sear connecting pin, the sear (128) is too far forward. Turn the sear positioning screw clockwise in ‘1/8’ turn increments until the trigger bar rises to connect with the sear connecting pin. Should the trigger bar rise and connect before the trigger reaches its foremost point, the sear is positioned too far rearward. Turn the sear positioning screw counter-clockwise in ‘1/8’ turn increments until the trigger returns to its foremost position.

If the trigger is not allowed to return to its foremost position the safety button may become inoperable causing a dangerous situation. The trigger bar and the sear relationship is preset at the factory for optimum performance and should only be adjusted by KID or a qualified gunsmith.
