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

"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.
