Pistol grip installation

BEFORE PERFORMING ANY DISASSEMBLY OR ASSEMBLY PROCEDURE:

a. Move the safety button fully rearward to the "ON" (SAFE) position and keep muzzle pointed in a safe direction.

b. Open the action, visually and physically check chamber, elevator and magazine tube to be certain the firearm is unloaded.

To Remove Buttstock:

1) Loosen the top screw holding the recoil pad or buttplate on stock. Note: Most models use Phillips head screws.

2) Loosen and remove the bottom recoil pad or buttplate screw.

3) Swing the recoil pad or buttplate around the top screw which will allow access to the stock bolt through the stock butt hole.

4) Check stock bolt head configuration. Some models use a slotted head,others use a 1/2 in. hex head.

5) Loosen and remove stock bolt by turning it counterclockwise. The stock may now be removed from the receiver.

Installation of Pistol Grip:

1) Align mounting hole in pistol grip with threaded hole in rear of the receiver.

2) Slip washers on bolt. Insert bolt through pistol grip into hole in receiver. Finger tighten bolt to insure threads are properly engaged. If you encounter difficulty, unscrew both and repeat procedure.

3) Using Allen wrench supplied, tighten bolt very snugly.

Upon firing, recoil force will cause the firearm to move rearward and upward. Never hold the firearm at eye level and attempt to sight down the barrel. To avoid possible injury, grip the firearm securely with one hand on the forearm and one hand on the pistol grip. Pistol grip models are designed to be held at waist level when firing.

SPEEDFEED® STOCK

BEFORE CLEANING OR REMOVING THE SPEEDFEED® STOCK:

a. Move the safety button fully rearward to the "ON" (SAFE) position and keep muzzle pointed in a safe direction.

b. Open the action, visually and physically check chamber, elevator and magazine tube to be certain the firearm is unloaded.

The stock springs and followers should be removed periodically and the tubes and parts cleaned to remove debris. Do not lubricate these parts.

The recoil pad on the speedfeed stock is under spring pressure. Remove rounds from storage tubes to minimize the spring pressure. Use caution when removing recoil pad screws to prevent injury to yourself or others around you.

a) Loose and remove the two recoil pad screws by turning them counterclockwise.

b) Remove recoil pad, springs and plastic followers. Place on a clean dry surface. TO REASSEMBLE

1) Insert one plastic follower into each magazine tube in the stock. Be sure the hollow portion of the follower is facing toward the rear of the stock.

2) Insert one spring in each of the two magazine tubes. The springs will fit inside the cupped end of the followers inserted in the previous step.

3) Screw the recoil pad screws into the recoil pad until the screw points come through the opposite side about 1/8 of an inch. Place the pad against the springs so that the end of each spring rests against the recessed area on the pad.

4) Compress the springs into the tubes by pushing the pad flush against the stock. Adjust the pad until you feel the points of the screws fit into the pre-drilled holes in the stock.

5) While maintaining pressure on the pad, tighten the recoil pad screws securely. Do not overtighten screws.

6) Check for free movement of the followers by pushing them into the magazine tube with your finger and allowing them to snap back into position under spring pressure.

HEAT SHIELD

^^ BEFORE PERFORMING ANY DISASSEMBLY OR ASSEMBLY PROCEDURE:

a. Move the safety button fully rearward to the "ON" (SAFE) position and keep muzzle pointed in a safe direction.

b. Open the action, visually and physically check chamber, elevator and magazine tube to be certain the firearm is unloaded.

HEAT SHIELD INSTALLATION =

NOTE: The heat shield can only be installed on 12 ga., plain barrel models. The heat shield will not fit on barrels with Ghost Ring® sights.

1) Follow barrel removal procedures as described in this Owner's Manual.

2) Carefully remove front sight by turning it counterclockwise. Take precautions to insure you do not damage the barrel finish.

3) Slide heat shield onto barrel from the muzzle end. The large ring on heat shield must be positioned towards the rear of barrel.

4) With the heat shield on the barrel, use a small padded "C" clamp or a vise, to close the forward clamp of the heat shield.

5) Position the appropriate length plastic spacer or optional bushing style spacers between the forward clamp. Insert the two screws and start the two hex nuts on the screws using a 7/64" hex key wrench and a 5/16" open end or box wrench. DO NOT FULLY TIGHTEN THE TWO SCREWS YET (Fig. 17).

6) Reassemble barrel to action.

A When securing heat shield, the barrel must be attached to shotgun. Barrels with heat shield secured are not interchangeable without proper refitting of heat shield to firearm as described in the above procedure.

Make sure takedown screw or magazine cap is secure and the barrel is fully seated before proceeding to the next step.

7) Position heat shield so that the rear (large ring) butts up against the front of the receiver.

8) Using a 7/64" Allen wrench and a 5/16" open end or box wrench, tighten the clamp screws to securely hold the heat shield in place. DO NOT OVERTIGHTEN THE SCREWS.

9) Reinstall front sight.

Whenever the heat shield barrel is removed from the shotgun, repeat the above steps 5-8 to insure that the shield is not preventing the barrel from being seated fully.

Whenever the heat shield barrel is removed from the shotgun, repeat the above steps 5-8 to insure that the shield is not preventing the barrel from being seated fully.

ACCU, ACCU-MAG CHOKE TUBES

BEFORE REMOVING OR INSTALLING ANY CHOKE TUBE:

a. Move the safety button fully rearward to the "ON" (SAFE) position and keep muzzle pointed in a safe direction.

b. Open the action, visually and physically check chamber, elevator and magazine tube to be certain the firearm is unloaded.

Do not use bent or deformed choke tubes as these may result in tube or barrel damage upon firing which may cause serious personal injury. Inspect choke tubes periodically to insure they are properly installed and in good condition. Pay special attention to the threaded end of the choke tube to be certain it is not deformed or dented.

Never fire this firearm without a choke tube properly installed. Failure to do so will damage the precision threads on the inside of the barrel. Firing this firearm with loose choke tubes may lead to damage to the choke tube and barrel, as well as serious personal injury.

CARE & CLEANING: The precision threads on your choke tube should be kept clean and lightly oiled at all times.

During cleaning of the barrel, be certain a choke tube is properly installed. This will avoid residue build-up on threads.

Extra-Full choke tubes are not recommended for use with buckshot or slugs. The "Improved Cylinder" choke tube will usually produce the best accuracy with most slugs. ^=ACCu-CHOKE™ TuBEs

AACCU-CHOKE™ TUBES - are designed for use with LEAD or STEEL shot. Each durable choke tube is clearly marked, as a guide, with the pattern it will produce.

TO REMOVE CHOKE TuBE: Loosen with choke wrench provided, turning it counterclockwise. When the choke tube is loosened, remove it completely with your fingers. Place choke tube on a clean, dry surface.

TO INsTALL CHOKE TuBE: Screw the tube clockwise into barrel by hand and then tighten the tube until snug with the choke wrench. Flush fitting tubes fit completely inside the barrel when properly installed. Do not use excessive force when installing. Tube tightness should be checked periodically.
