Type 99 Deactivation

[Doco overboard]

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.

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.

I would suggest doing what I've done for 35+ years in displaying my rifles......don't put any live ammo in it and it will not hurt anyone!

That's the best advice ever!

Just have him get one of these and you don't even have to worry about dust.

If you need matching trigger locks look me up at one of the shows or email me I have a few cases of them,
It would be better for a display firearm to put a used broken firing pin in place of the good one, If used one can not be found buy a repo an cut that.
Of all the parts ai sell every weekend the firing pins spring an extractors are that big demands. Some being next to imposable to find.
Collectors are buying up everything they can, Shooters are smart in my mind to take there good original ones out an use the repos.
We are faced every weekend with securing are bolts so none are stolen because of the shortage,especially the japs,

Thank you to all for your feedback. I'm still engaged in the project, but I've been off line for a while.

Thanks again.

turn a bushing to go around the shank of the tip of the firing pin. may take a little trial and error but should prevent possible firing

[USMA79]

I've been thinking about replacing the firing pin with a section of dowel rod. However, I won't have access to the rifle until the day I meet with my friend, and I've been unable to locate the dimensions of a Type 99 firing pin. (Lots of photos, but no measurements.) Does anyone who is following this thread have a schematic with dimensions?

Thank you again for all of the input.

dowel wont maintain the safety to the bolt

I would take that piece of dowel rod and epoxy it into the chamber with a low strength epoxy. Like the others have mentioned, firing pins are expensive and this way the bolt can still be worked, using a snap cap or spent caae would be hard on the extractor.
