"Some people say the WE makes very bad quality products but they say that because they have never had a chance to actually use and play with a WE gas blowback rifle. I can tell you right now that this is the best rifle i have ever owned. I'm a huge H&K fan and I wanted a H&K 416 that was not a VFC so I gave this a shot. I've had the gun for about 2 months now and have had no problems with it. No words can describe how awesome this gun is so here is a list of pros and cons.....

-Superb quality (full metal lower and upper receivers)
-Amazing recoil (almost like shooting a .22 long rifle)
-Great gas efficiency (about 3 mags on 1 fill)
-Good weight
-Great accuracy
-Easy to break down and clean
-Crisp blowback and trigger response
-You have the option to go from a 14.5 inch outer barrel to a 10 inch CQB length outer barrel (more on that later)

-Hop-Up Adjustment can be tricky
-Needs to be lubed alot (I expected that since its a gbbr)
-30 round magazines will put you at a slight disadvantage against aeg users
-Your plastic nozzle will break if you try to cram more than 28 rounds into your magazines
-Fps is really hot for indoor (buy a npas)
-Cold weather is not your best friend (lol)
-You don't have this gun yet

How to remove outer barrel extension
1. Dissemble the gun fully and remove outer barrel
2. Take a small drill bit and drill out the first pin near the end of the extension (you will know when you are done drilling because you will drill thought the threads
3. take your outer barrel and drop the end of it into boiling water to soften up the glue holding the to parts together
4. Get some vise grips and grip one end of the barrel down
5. Grip the other end of the barrel and turn as hard as you can until it breaks free and twists
6. You now have a CQB length H&K 416

A Few Words:
Get a Angel Custom 6.01 tight bore inner barrel
Get a REAPS bucking
Get an RA Tech npas ($20 buck right here on Evike)
Lube and clean often
If you take care of this gun it will differently take care of you

Give WE tech another shot

"This was my first gbbr and I'm EXTREMELY happy with this.
Other reviews have maybe mentioned or not but I'll try to go cover everything noteworthy.

The orange flash hider is aggravating as any other to get off and takes time. You can find how to remove it anywhere. The outer barrel sticking out can simply be twisted off by turning clockwise.

The rail system is VERY easy to disassemble. Simply twist off one large screw and the entire thing pulls off. This being my first gbbr I was utterly dumb founded by how sturdy and tight the entire thing felt with one basic screw. I would suggest at least half finger gloves if you're using this without rail covers. The rail is a bit sharp.

First time taking this apart I was able to install the 280 mm angel custom tightbore and 75 Maple Leaf bucking & Angel Customs NPAS (have review of that if curious) I've gotten confirmed kills at 220 ft. and this wasn't even meant for field play.

The hop up unit is a simple but very good design so far. My only complaints are the screw that holds the unit together is very small and can strip easily so BE CAREFUL.
Adjusting the hop up itself is a pain. It will require a lot of time really trying to dial it in. The screw you need is a 0.05 mm Allen screw and be careful to not be forceful otherwise you will strip this screw as well.

The biggest problem I see with this gun for most people is that the bolt catch is not very good. Wore down easily and was no longer catching. I had to do some dremeling but it's working every time now. Look for boobiegbb on YouTube. Best guides I've found.

One of the trigger group pins came out so I bought the spare parts package here for 25$ and it ended up being a lot more useful then I initially thought.

Taking apart the BCG is simple but just be careful and make sure you're organized or you will loose small pins.

I made the mistake of loosing a pin spring so my rear reciever pin kept falling out. If you want to put an ASAP sling mount on then be sure to catch the tiny spring that sticks out. This pushes a pin into the reciever pin which holds it in place. Without it the reciever pins WILL fall out.

The stock is the only thing I found to have wobble on my gun. Everything was tightly secured.

I've run this through several games and had outstanding performance in field considered this was meant as a cqb gun.
I would suggest murder oil to keep it well lubricated and if you're up to it some DIY to make it super efficient.

All in all this is a GREAT rifle. Personally I wanted to do all the TLC since it was my first and the experience was well worth it. Would definitely recommend to friends.
