"Alright i started off thinking that this gun could stand a little bit of CO2 use before i got the RA tech upgrades...well i was entirely wrong i put the mag in shot fantastic for like 3 mags worth then its not working so i pop the pin check whats going on and where the real extractor would be all the way in the back had actually ripped apart and my friend and i tried to repair it well that didn't work.But staying on track it was a rather nice gun for the first couple mags felt amazing to shoot and looked great too little sad there wasn't trade marks but we cant have it all. Its rather accurate and feels nice in the hands but this is the last time I try GBB. So all in all buy the gun if you want to put upgrades in it as soon as you get it or run green gas with it till the upgrades then try more stuff. Along with that watch out for your trigger box it can go bad with extensive use on full auto or rapid semi-auto fire.

"This is my first gbbr , the quality is good , good price, adjust the hop up is a bit difficult. cleaning this replica is easy. i buy five magazines, an inner ra tech 6.01 , an npas ratech ( Appears out of stock online but u can go to the store and They have it ) and a maple leaf 70 degrees and it works fine sthe Improve acuraccy and fps. I absolutely recommend this replica .

"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
