H&K Umarex HK416C Full Metal Airsoft AEG Rifle by VFC

"I've had this gun for 4 years now. It's been my cqb and woodsball primary ever since. It's been dropped from a humvee, rained on during several OPs, splashed from heavy mud from milsims. No cracks at all. Minor rusting on 2 rail screws. (Insane for all the rain it's gotten)
1.) Upgrades over the years
Rewired to the back
Moe stock+ new buffer tube
Madbull 6.03 barrel 363mm (longer barrel)
Mock supressor to protect barrel
16:1 gears
Rewired to deans
New piston+head, cylinder+head, air nozzle, m120spring
2.) Pros
Holy cow do I stand by this gun. Never once have I had a malfunction in 4 years of intense play. I could honestly say when I purchased this thing I knew eventually I would strip a lot of the few plastic internals overtime for metal. The outer shell with everything is extremely light weight which I love. Shoots "Rifleman" as 1.29Joules with .2g's (with my current upgrades)
3.) Cons
So I love the cqb look, but from intense outdoor play the peq box wiring was becoming stripped. Rear wiring the stock to an moe allowed a stick type 11.1lipo and fixed this.
By simply pushing the 2 main bolts you can slide your upper off from the lower, but putting it back in was a pain. Took channelocks and bent it slightly to fit easier for maintenance fixes this. I recommend a tech only do this so you don't crack anything.
Some of the internals are plastic sadly but they will certainly hold up on a 7.4. Get a little dicey with an 11.1lipo and expect an air nozzle or something to break eventually until you upgrade. (Externals are amazing tho)
4.) Overall I give this gun a solid 4.8/5
Some good enough internals to last me 6-8months before I did some internal work with no breaks(personal preferance). I wanted to make this thing last
Personally the only other upgrade would be replace the trigger contacts with a mosfet. I've taken this gun apart only 3 times for upgrades I wanted. :) Hope this helps -Cowboi from Echo4

"For starters, I bought this gun purely so I could be Jäger from Rainbow Six Siege and because I've never used an AR-style platform before. If that's what you're trying to do, maybe find something else or just get the HK416 CQB. Anyway, this gun is pretty good, I think. A lot of positivity with relatively low negativity. I've poured around 400 dollars into this baby and I'm telling you, it's werf (any RussianBadger fans out there?).

Externals: I mean it's VFC. They're pretty top notch. Can't really find any fault with them.

Internals: Lemme tell you up front that I haven't the slightest clue about airsoft internals, but either way, I had mine upgraded with a flathop, new motor, and piston. Only thing I can say is what the tech told me which was that VFC pistons are apparently pretty underwhelming.

Pros:
Full metal, add to realism but could be a con
Perfect for CQB and decent for field
Lots of rails and rail space
Pretty accurate out to 120 feet
LiPo ready
Comes with a really nice magazine, fully trademarked (but it's actually more of a showpiece, I'll talk about it in cons)
It's rather unique among M4s and AKs
Trademarks all day baby

Neutral:
Unsure about whether stock is better opened out or closed, closed feels better against face but out feels sturdier
Trademarks do eventually wear off and fade away, moreso if you touch them directly with your hands
Rear ironsights are kinda janky but I think front sights are a bit more effective anyway

Cons:
Good God the battery was probably my biggest issue while I was buying this gun, I had no idea what would fit in the included PEQ box, so I'll provide a link to a good battery that fits nicely in it (http://www.evike.com/products/36324)
Even with the included magazine, this gun is pretty picky on what mags it wants to take and how it takes them in
Probably my current biggest issue is the underbarrel rail: the lip at the front of the gun essentially blocks any grip that slides onto rails, for example, I have a Magpul AFG that is unable to fit onto the gun because of the lip; in short, have a grip that can shimmy into place or can screw out and back in

In conclusion, if you want to cosplay Jäger, go for it my dude, if you're looking at this through a purely airsoft and efficiency filter, I'd still say do it. Get past the few minor cons of this gun and enjoy it. It's been on sale since I wanna say July and even until now it still is. I'm beginning to wonder whether or not it's going to be discontinued or something. I suppose that's incentive enough to get this gun as soon as you have the money for it.

"Is a very good gun if someone has problem about the battery box, you can buy a PTS Enhanced Polymer Foregrip to put the battery in it so you don't need to worry about the ugly PEQ battery box.
