good morning sirs;just want to ask if this spring ( the longer one is a gng striker spring) i have seen some samples in the net that the gng spring is a little thicker;the long one in the pic came with the set that i bought second hand;by the way the shorter one came from my tanaka bolt;stock

 

[Wolfgeorge]

I'm not sure... If I remember correctly the G&G and stock had about the same size.
I couldn't install the G&G spring in my bolt, the spring came from the power pack, I've read that if you buy it separately then it works in all bolts.

I think my spring was very similar in lenght,but thicker.
i know you are ment to get better results with these but I changed back as it also made the bokt handle harder to lift , which was oe of the things I love aboyt my tanaka.

The one on top, even if bent terribly , looks like a G&G Striker Spring, I have both that one and the King Arms Striker Spring. The latter is by far the sturdiest, strongest spring for Tanaka rifles, but the G&G one is pretty strong as well, compared to the stock spring.

Actually, the stock spring in my possession has another auxiliary spring, shorter and very thin, that needs to be placed before putting the stock main spring.

For some reason the G&G Striker Spring scratches against the inside of the bolt and does not slide correctly..maybe applying some serious greasing would help but I opted out for the moment and - since I was restoring the rifle from over a one year break - I installed the stock spring.

I don't know if this can help you, but here is a picture of my G&G Striker Spring and King Arms Striker Spring.

I have a new one here, the short thick one is the G&G the longer thin one is stock:

thank you sirs for replying looks like what i have now is the stock spring then;the long one in my pics was the piece included with the powerpack parts;which i got second hand;( longer spring );thank you sirs will be looking for a gng striker spring soon

followup question sirs:
when you installed the g&g striker spring;what was the fps in greengas with the standard .2 bbs< just for comparison purposes;
same question with the kingarms striker spring;and did you pair this with the stock bolt assembly or did you buy the g&g power bolt already?thanks

I didn't chrono the difference (no chrono around for the moment, sorry!) but all the info and details I gave are related to the stock bolt, not the G&G Power Bolt..

*begin OT*
..which I heard being very sturdy and reliable but with less features than a PCS bolt and maybe slightly out of spec with the nozzle length (needs further verification, these are just details I read here and there on these forums).
*end OT*

I noticed that when I would gas the mag with the stock spring I would get a weak shot, then progressively stronger, then weaker as the mag went on.

This led me to believe that the stock spring was not strong enough to push the valve fully open when the mag was full of gas, so I got the upgrade spring which is significantly stronger.

After that my first to last shots were much closer fps wise, but I don't recall them being higher than stock.

I would also recommend switching to the G&G Striker spring or the King Arms version.

Bear in mind that, since this is the chain of events:
1. Striker Spring releases tension ..
2. .. pushes the valve knocker (inside the trigger) against the impact plate (on the magazine) which..
3 ..opens the magazine valve (on top of the magazine) and lets gas flow out

By using a reinforced spring you are putting the entire firing mechanism under more stress. It is not mandatory but it might be a good idea to replace these parts with steel upgrades. Remember that once you use one steel upgrade, you will tear down the non-steel upgrades that hit on or get hit by the steel ones. If you can, go full steel.

Nothing "mandatory" but check for signs of wearing so that your rifle doesn't break down on the field.

Upgrades worth checking (for reference, in random order):
- G&G Steel Valve Knocker
- King Arms Magazine Steel Impact Plate
- G&G Power Set

Notice that the G&G Magazine upgrades sometimes leave the magazine valve open..so the King Arms Impact Plate is a better solution. The G&G ones worked great on my stock Tanaka magazine but for some reason I wasn't able to install the properly on the long magazine, so I used the King Arms Steel Impact Plate.

nice;will also look into this sirs;so far what i have installed are the powerpack set;will check the steel impact plate also for better reinforcement;thanks sirs

If you installed the G&G Power Pack on a magazine, you don't need the King Arms Impact Plate. They are different approaches for the same purpose

On my long magazine, the G&G Power Pack would keep the valve open so when I filled it the gas would go out immediately from the valve on top of the magazine..so I installed the King Arms Impact plate and it worked perfectly.

My stock Tanaka magazine has the G&G Power Pack and behaves perfectly..go figure!

this instance happened to me a while ago;
stock tanaka m700 mag with installed gng plunger from the powerpack;the knocker arm that came with the gng ;i did not install;just the plunger;if i placed a lot of gas in the mag;i can hear the gas coming out from above the mag the outlet where the gas comes out

what could be the problem sirs?

 

[Wolfgeorge]

It looks like the o ring needs replacing.
Or the spring under the valve got softer!

I couldn't either install the Power pack in my AICS, I only installed the impact plate.

For some reason some of the G&G Power Set pieces, when assembled in the magazine, produce a slight offset that keep the valve open. I myself would fill the gas in the magazine and see it come out directly up front from the main valve..eheh.

Since it is very hard to look inside the magazine while testing it, it became challenging for me to find the culprit of this problem..

The King Arms steel impact plate does not have this problem since it works differently, basically it does not interfere with the internals of the magazine, it just replaces the external plate with a steel version.

nice posts sirs;it answers a lot of my questions;kudos to all of you

As usual, glad I could be of assistance!
