Type 99 Deactivation

[USMA79]

A friend has asked me to help deactivate his Type 99 rifle for display. He doesn't want to do permanent damage to the rifle, but wants to ensure it cannot be fired. I was thinking of removing the firing pin, but I'm concerned that without the firing pin in place, the reassembled bolt may not stay in one piece. (I've run into a problem when removing the striker from the U.S. Model 1903 rifle.)

Does anyone have any suggestions for deactivating a Type 99 for display without doing permanent damage to the rifle? Thank you.

Keeping in mind that this is NOT deactivation according to the United States government and you want something reversible....
I'd just get a Snap Cap of the appropriate caliber, slather it in epoxy, and insert it in the chamber. A propane torch would provide plenty of heat to reverse this whenever you wanted but it would prevent anyone from immediately firing the rifle.

EDIT: You could also simply clip the end off of the firing pin. That would take an even more determined individual to reverse. But it does alter the current pin permanently.

Why not use a trigger lock that slips into the trigger guard and renders the firearm safe from manipulation but doesn't change or damage it at all...about $12 CDN, US would be cheap I should think. Here's one...

I would melt cerro-safe into the chamber and bore a little bit up to an oily patch. I would not break the firing pin they cost to much to replace.

What's wrong with the trigger lock?

Trigger lock looks like crap if you are hanging it on the wall. Down here the police and fire departments give the things away if you ask for one. It is probably a very good solution however. Take a part out, you are going to lose it. Snap cap glued into the chamber seems like a viable option also.

You could also just wedge something like a small piece of mixing cup stick or shim stock in between the sear and the receiver. Towards the front in between the sear pivot pin and sear spring. If you increase the height of the interlock stud same thing but it will make it hard to open and close the bolt.
