Hei

Just bought a used 416D NGRS. was told the recoil was broken but the rest was good.  Not the case. I am a technical type of person but have not worked on airsoft guns before.  My problem is finding out whats wrong without taking apart the gearbox.. 

Question one. Does the gun function if the NGRS does not work? 

Question2: The Gaspiston thing on the outerbarrel. Is it connected to somtehing ? Or does it just enhance the recoil?

Pic 2,3,4,5  shows the gearbox with the NGRS thing  I dont know what to look for to se if anything is broken but the parts move freely and smooth

Question 3   The littel gismo that is on the back of teh recoil thing (part 416-26) has a chip in it, but it stays on when i fire the rifle

Question  5:

The one thing i have found that i think might be fawlty is the nozzle. When i shoot semi the nosel does not come back to the same position. Its  a couple of mm off every other shot.... I got a youtube video showing the problem

 Nozzle movment video (youtube)

The 416 sounds a bit wrong on auto also

funny sounding auto

OK that was a lot of questions and a lot of pics  but i need som serious help.

Im in Norway so there is not a lot of techs around 

Thx in advance.

PPS Sorry for not knowing the  name of al the parts . The only exploded parst view i have found is not in english

Firstly matey who did you buy this off and did they mention those faults before you bought it? It’s totally unacceptable if the seller sold you any rifle and didn’t tell you. I’d have not opened it up and demanded a refund! Period. 
 

Having said that all is not lost. The recoil platform is very simple to work on. 
 

Q1 - the recoil mechanism has  a number of components. The main recoil unit is in the buffer. This is what gives you the recoil. On top of the receiver you have the dust cover recoil affect. This does not affect the main recoil. It’s there for immersion and looks. From your pics you have a spring missing. This is my 416’s charging handle recoil unit. See the difference?

The way the top recoil works is via the piston. You’ll see a gap at the back of the gearbox. This is where the hook of the upper recoil unit goes into and when the piston Is pulled back so is the top recoil unit. It’s a clever and effective mechanism. 
 

I’m actually taking my 416 apart this weekend as I’m upgrading it. I’ll take pics if I can. However from your video that clanking sound ain’t right. Take the buffer tube off and show me the spring guide. Also does your spring come out without you taking the gearbox apart. If it does this means the spring has more than likely been upgraded. The clanking sound may be the piston head is loose from the piston. This can happen if the person who did the upgrade didn’t screw it back to the piston properly. 
 

Also check out the Eagle6 disassembly videos. They are really good. Also Dave’s custom does a great video too and also Kingdom of Airsoft. 

 
@SgtO2 I can’t see clearly but I thing the nozzle is incorrectly located, there is a little notch in the end of the nozzle and this has to point downwards/toward the magazine.

Post a better pic of the nozzle.

I saw this advertised as having a hop/feed issue.

If what I have suggested is the fault then you will have to strip down the gearbox to remedy it.

So you may want to have a word with the seller first.

@AlphaBear Save having to start a new thread - do you know the size of the star washer for the recoil bar?

It's a starlock washer I do believe... I'm afraid I don't know the size... Probably best to measure the recoil bar with callipers and then buying a pack..... however it's not essential for the recoil bar truth be told... It's an easy one to lose too... I'm sure it's missing from one of my recoils too...

 
Hi again. Sorry for not posting in a while but we have the longest Easter hollyday in the world here in Norway ?  And i have tried to contact the seller but no luck  

 I think the nozzle is the right way but ill post some pic’s.  Next on the agenda is removing the buffer tube to see if the spring is loose.  Can i do that without removing the deans? Do i need a special tool to remove the large Nut or is a wrench OK?

I can’t really tell if the nozzle is fine. It does look a bit battered though. I’ll post a picture of a Marui nozzle later today. 
 

To remove the buffer tube but you need a correct wrench. Don’t use a normal wrench as you will ruin the nut. You can also unscrew the buffer tube without taking the deans off but and this is a big but you have to do it carefully so that the barrel nut does not cut the wires when you unscrew it. I suggest looking at the Eagle 6 videos first. 
 

They show how to disassemble a Marui recoil SOPMOD.

This is what a stock Marui nozzle looks like. And the first photo shows a small indent at the bottom of the nozzle head. This must be facing downwards towards the gearbox. 
 

Your nozzle is attached correctly. In fact it’s difficult to get that wrong to be honest as it’s clicks into the tappet plate.

I finaly got the castle nut off. ?

THe spring does com out when i remove the buffer tube.   Here is some new pic's

View attachment 72193View attachment 72194View attachment 72195

So this means i the spring has been changed.   Do i need to open the buffer tube? 

THe piston has a little nob inside, right at the bottom.  

 
Got the buffer tube open .

 View attachment 72198

Looks OK to me . A bit of lube and ill close it up again.

Im a bit unsertain about the order of the washers. I think the ballbearing one should be in the middle.

Hi again

Have managed to open the gear box. The motor is a bright orange nupol so thats not stock i think.  Im not sure i can identify what is causing my problem but i got some pic ?

The gear looks like it has been filed down on purpuse, one thooth is missing.

View attachment 72552 View attachment 72557

The other gears looks fine to me.

View attachment 72555View attachment 72554

The tapper plate looks fine but the piston looks realy worne out. 

View attachment 72559View attachment 72560View attachment 72561View attachment 72562View attachment 72563

Any tips on whats to throw out and buy new?

to put it back to stock you need a new piston and a selector gear. The piston is dead but you can easily find a replacement (prometheus being a good choice). The selector gear looks to have been grounded out to play around with the AOE but to get the AEG up and running its best to get a new replacement.

the whole gearbox needs a very good clean and re-lub to be honest.

Once you have it back to stock and working then you can go crazy with the upgrades (replacing the trigger contacts with a Titan is highly recommended as the NGRS platform goes up an notch when you add a better trigger system).

Also because the gearbox looks dirty I'll really check out the inside of the inner barrel and give it and the hop rubber a really good clean.

 
Something like this?  My spring fell out before i too the gearbox apart. Should it not be attached to the piston?  Should i go stock £30 or prom £60 (35+25) ? Looks like the TM is both head and piston for 30 pounds.

If your spring fell out because it’s non standard.

The gear has not been filled like that, it’s knackered.

What are your goals with it?

Run it stock-ish or you want to mod it loads?

I have all the standard internal parts in good condition if you are interested.

Gears, motor, piston complete.

Otherwise, I would go Lonex gears, Prommy piston.

 
Im trying to get this thing up and running. Stock is is great for me.
