The HK 416 GBBR by VFC

Recommended Posts

VFC engineering at it's finest?

 

So my HK416C(2015 version) just arrived. It comes with the new magazine. For some reason they switched the flash hider to a simple M4 style birdcage one.

WGC was nice enough to chrono the gun before sending it to me, however they left the magazine full with gas and some BBs. :P

After a bit of cleaning and relubing I put in the mag and shoot the gun. First shot worked fine but the second trigger pull simply let the hammer go and nothing happened.

I examined what might be the problem and I found out that the mag was not seated correctly. Oh well I just push it in harder or so I tought but nope! The magazine would not move inside the magwell any more despite the magazine catch clearly not keeping the mag well.

So first I took apart the gun and inserted the mag in the lower receiver with no upper on it. The mag seated right. I assembled the gun again, inserted the magazine which again would not seat right and after I pulled the bolt back I noticed that the magazine's real steel lip imitations are already hitting the upper receiver's sides. These ones:

However if I kept pushing the mag in while shooting the gun it worked fine it seemed there was a good contact between the mag and the nozzle. So I looked under the magazine catch:

So the question is what should I file down: the fake lips or the mag catch? Also the bolt seems really sticky(I polished it only a little).

Edit: or just file the part of the magazine where the mag catch goes in.

 

I would file down the upper receiver instead.  thats the issue anyways, the magazine will fit a standard M4 so its the tolerances on the upper that needs modding.

Last weekend we made a comparision video about using 2nd gen VFC magazine or GHK G5 magazine. There are a few guns but you can see the difference when we use two HK416.

I have the m27 version and would like the option of converting it to a standard hk416d model. Am I right in saying all id need for this is a shorter front end and outer barrel as well as inner? Where would be the best place to source these parts?

Directly from VFC.  Send them an email to their sales department and they will take care of you.  Sometimes they are slow to respond and sometimes you have to send the request twice, but you will get your parts.

As I said I took apart the mag and filed the upper part of the hole where the mag catch goes in until the magazine seat fine in the gun.

I think I'll just carry it back to the store..

It already started damaging my bolt carrier because the mag was giving upwards pressure on it :(

Thanks for the reply, I obviously read over your previous reply :)

Upper reciver and buffer tube threading destroyed, internals grinded down without lubrication (I just use it for display now. But was kinda tired messing with Co2 on the 416) 

 

I am currently looking at tippmann m4 HPA but i really hate that sircle thing in the midle of the M4. Do you know if there is anyone who have swaped the internals from the tippmann m4 to the Hk416?

How did the 416 become that?  Those VFC buffer tubes will work fine on a 556 platform I can't see how it can't cope with CO2, UNLESS the recoil spring wasn't strong enough on CO2 and there were no additional rubber buffer at the end of the stock tube.

here is a picture of it, if i screw the buffer tube to the lower reciver it is still loose when its fully screwed on.

as you can see here, there is a crack in the buffer tube

I could but i want to run HPA tru my pistol grip not via the magazine. So thats why i am thinking about buying a tippmann m4 or a new HK416 Polarstar HPA but the drawback on the polarstar is no recoil :(

Go datona gun then, I'm no fan of the tippmann system and I no like p*.

 

Tbh I'm no fan of hpa systems at all, if you want gas and recoil stay GIM.

Soo i bought new lower and buffer tube for the 416 from the manufacture directly the 14th of mars and they said it will get sent as soon as they recive payment, i sent the payment and they have not sent any tracking number even when i sent request on email for tracking number they are just ignoring me. Soo should i get worried?

 

 

and btw: i got the daytona gun parts for HPA setup and will finish the conversation as soon as i get some other parts for the gun :) i will update on how it performence after i have gone tru the 8k rounds (break in the gun)

So I'm considering buying this gun and learning its internals and how to maintain it. If anyone owns this gun, I'd like to hear about what to do with it once it arrives. Parts upgrades, known problems, anything that has to do with the gun working properly. I know VFC has quality externals as I've seen in videos and pictures, but I read on this forum that the internals might have problems.
