How to Change a Savage Model 110 Stock

Lay a towel or a cloth on your work area to prevent scratching your Savage 110.
Check to make sure that your rifle is not loaded. Remember gun safety rules, and even though your rifle is not loaded, do not let the barrel point towards yourself or others.
Lay the rifle on the towel. Turn the rifle so that the bottom is facing up, and the sights (if present) are laying on the towel.
Remove the hex screw on the forearm of the rifle. It would normally be positioned on the bottom of the rifle, but because the rifle is upside-down, it will be facing up. Use the appropriate size Allen wrench, as different year models of the Savage 110 may have different screw sizes and tolerances. As the hex screws are removed, pay very close attention to which hole they came out of. The hex screws are not interchangeable, and must be replaced in the same location.
Remove the hex screw from the front (towards the barrel) of the trigger guard. Leave the hex screw at the rear of the trigger guard in place.
Remove the rifle stock. It will pull off easily in one piece, with the trigger guard attached.
Remove the hex screw at the rear of the trigger guard, and remove the trigger guard. Some replacement stocks come with a new trigger guard, but if yours does not, then you will be re-installing yours on the new stock.
Place either your existing or new trigger guard in place on the new stock. Using either the hex screw you had removed from the rear of the trigger guard--or the new one supplied with a new trigger guard--screw the rear hex screw of the trigger guard into place until the screw is seated snugly. Do not over-tighten any of the hex screws.
Place the replacement stock in position on the metal body of the rifle.
Using either the hex screw you had removed from the front of the trigger guard, or the new one supplied with a new trigger guard, screw the front hex screw of the trigger guard into place until the screw is seated snugly. This screw pulls the new stock and the metal body of the rifle together.
Take the hex screw that was removed from the forearm of the rifle. Position it in place, and screw it in until it is snug. Your new Savage 110 stock in now attached.

How to Remove an SKS Stock (10 Steps)

Flip the switch on the right side of the rifle to a vertical position and pull the pin outward.
Remove the receiver cover and buffer assembly by gently pulling backward.
Pull the charging handle back to remove both the bolt assembly and the charging handle.
Turn the rifle upside down and set it on a smooth surface.
Use a Phillips screwdriver to press down the button behind the trigger loop. This will cause the trigger assembly to pop up. Be careful: The trigger assembly is spring-loaded.
Turn the rifle over and lift the barrel assembly out of the stock.
Flip the lever in front of the rear-sight post to release the gas tube assembly.
Remove the gas piston.
Using a small nail or hole punch, push the retaining pin out of the back of the rear metal cover of the handguard.
Remove the wooden handguard. You can now attach the new stock.
