Don't bother with Tanaka's... They are way overrated.
They have too many problems and they break down fairly easy and the biggest drawback is that they have no replacement parts!
I mean other than the hop up area.. Like trigger and parts in the receiver.

I'm sorry to hear you've been fooled, hope to sort this soon.

I haven't seen up close a KJW bolt but that looks amazingly like a non PCS Tanaka.
The Japanese ban happened in the early 2000...
Basically if you drill the nozzle or replace it with an unrestricted you'll have it like the PCS bolt in it's max position.
The bolts are the same internally.

Take your gun apart and check the hop up bucking, also take a look at the impact plate of the magazine and the valve knocker(sear) in the magwell fie wear.

Also take out the 2 small screw on bolts bottom side and check if the screw that holds the striker spring is tight.

Basically these are the only things that can go wrong. My guess is the striker spring screw is loose.
I've seen wear on the sear after quite a few thousand shots!! Installing a new one was real pain... I hope it won't happen to you!
