Anyone know how to take down Nambu

First, remove the magazine and assure it is unloaded, then pull the trigger to drop the firing pin. At the cocking piece, push in the button in the center, hold in and unscrew the cocking piece, removing it and the firing pin guide, spring and firing pin. You will have to pull the trigger and tilt the gun muzzle up to get the firing pin to fall out. If it doesnt, dont worry you can get it out later.
Next, remove the grips. Then push in the mag release button and push the muzzle against a hard surface to push it back slightly, then slide the trigger group downward and remove. The barrel and receiver group can now be removed. Slide out the bolt with the springs and if the firing pin is still in it slide it out too. The locking block should be on the receiver and it can now be removed also.
After everything is thoroughly cleaned and oiled, it basically goes back in reverse. Put in the firing pin, spring and guide last and pull the trigger as you put them in to let the pin go forward. Make sure when you put on the cocking piece you get the notch in the guide to fit into the corresponding notch in the cocking piece, then screw it in. Just before you get it screwed in, push in the guide (button) and hold in while you tighten up the knob. Then back it off till the guide "pops" into place. You will see what I mean as you assemble it.
The trigger group may be tight when you try to remove it. Just give a tug to it downward and dont hit it or pry it. Make sure the mag release button is pushed in when you do because that is what holds it in. Soak it in solvent or a penetrant if it still refuses to budge. Many of these Nambus were used in tropical climates and have alot of rusting and pitting so sometimes its hard to get them apart if they havent been apart for years.
Dont take it apart further unless you know what you are doing. It is easy to break the safety lever or lose little springs and parts so just dont do it.
