"I have had this rifle for 3 years. Yes I've replaced parts, but such is the life of an air softer.

I HIGHLY recommend the Co2 mags. I use them and this rifle is still serving me well. I've replaced the hop up rubber, inner barrel and some furniture. This rifle is absolutely amazing, and makes one heck of a gnarly sound when it shoots. During the local fields days of indoor, this rifle was the bane and fear of everyone's existence.

Unfortunately the bolt carrier eventually wears out, and will need replaced. But it's been 3 years and I still haven't replaced it. The bolt on mine no longer stays open on the last round.

Pros: Good weight
Solid construction
Awesome sound
Reliable with Co2 mags

Cons: Parts wear out the more you use it
Parts are weird, so you have to substitute or special order sometimes(Evike now carries all parts for this replica).

"this weapon system stock shoots about twice as far as my double eagle UMG with upgraded barrel and hop-up but is less accurate because I'm shooting at 150 to 200 feet.
i use .3 gram BB's because i live and play in windy areas with tons of brush.
evike has the LOWEST prices on the market

"Received the rifle about a week ago. Delivered on time and packed well. After reading several reviews of this rifle, the first thing I did was strip it down and clean it. Lubricated everything and re-assembled. Loaded the mag with .30g BBs and gas and had some fun. I did need to adjust the hop up as it was shoot low. Once it was dialed in I was getting a very tight grouping at around 45-50 feet.

Did not have any issue with the mag leaking gas, in fact, I could unload all 30 rounds and additional 15 before the gas gave out. There were no issue with the fit of all the pieces, Every thing was tight and fit well

Very impressed with the fell and weight. If you are use to lighter AEGs it may seem heavy. I do like the fact that the clip mimics the real steel counter part when it come to the amount of BBs, seems more realistic. While spraying several hundred rounds may be fun, it's more of a challenge wen you have a limited amount to shoot with on the field :-)

Bottom line this is a great gun at a great price.

Pro/con (depends how you look at it)

- Loud crisp firing sound


- Good weight and feel
- Realistic amount of rounds
- Solid construction


- Costly magazines
- Hop up difficult to adjust

"Just received this gun yesterday, and it is amazing! build quality is excellent, it doesn't feel clunky or cheap. Internals were pretty dry when i took it out of the box, but i broke it down, lubed it up and then took it for a test fire and was amazed with this rifle! i definitely recommend this to anyone looking for an amazing experience! 5 stars from me! thank you WE TECH and thank you Evike!!

"Got mine for Xmas and boy it was WORTH IT! playing Airsoft for a awhile, i wanted something different then having a AEG with 5,000 rounds and this rifle makes it a challenge to have just 30 rounds, and its ok because the challenge was what i was after. The only complain i have was the outer barrel if you can take it off to make it CQB barrel and adding a suppressor. Overall this gun is meant for EXPERIENCE players who want a challenge then just pulling a trigger shooting 5000 rounds and call it a day. Having this gun maintenance is required with lube after you shoot for fun or after games. 5 out of 5 for me! Thanks We Tech you guys rock!

"I got this gun about a month ago and I must say I'm very pleased with it. it shoot smooth, good trigger pull just a hair of over travel but it doesn't bug me to much. also every one complains about the paint it has only shown metal in a few spots of high wear locations, IE charging handle latch, selector switch, and around the mag well. this was also my first GBBR so the battery of arms took some getting used to

a joy to shoot
smooth shooting
trigger pull
can out range AEGs in most cases
works in colder whether (especially with C02)
real steel parts
mag weight (could be a con)
real steel training value

battery of arms takes some getting used to if not already familiar with it
came dirty
need a lot of mags

over all worth it just because of how much fun this thing is on full auto with C02

"Just got this gun after having the WE PDW for about a year, quality is top notch. I'm a believer in WE GBB guns. I took off the front handgaurd, added a daniel defense omega-x 12" front RIS and a 150mm silencer to house a new angel custom 6.01 500mm tight-bore barrel, fits perfect. You can easily swap out the handgaurd for rails or whatever you want because it has a delta-ring like any aeg, so all the aeg RIS's work on this gun. One other thing I always do when I buy a WE GBBR is get the angel custom vsr-10 hop-up bucking (red one) and an NPAS valve to adjust velocity. This gun is truly a solid platform that performs great out of the box, and wears modifications nicely. If you are thinking about getting this gun, I HIGHELY recommend it, easy maintenance makes it perfect for a first-time GBBR user and it's performance and mod-ability are great, so it's a gun you can keep and upgrade as you want.

"Just got this gun today and kicks ass!!! Like the heavyness and the easy maintenance

Pros: heavy
High fps
Easy maintenance

Cons: except for the hard reloading in the mag none
by Andrew H. on 04/13/2012
"Just received this today, figured I'd give the public some insight on the WE Tec M4.
This is a wonderful gun, 1:1 scale with an Colt M4A1, everything works perfect, and this weapon it awesome.

"This rifle rocks! I got this rifle about 6 months ago, I am from Wisconsin so usually gas guns do not work in the winter even for indoor cqb. My local club I play indoor cqb is heated to about 38 degrees and this gun will cycle full mags, on full auto all day with no problem. However I would recommend buying the RA-tech NPAS so you can drop the fps to cqb level. (the NPAS allows for adjustable fps and its only $20). Also this gun will out range a good amount of snipers in the field. Also dont get shied away because the mags are "expensive" and only hold 30 rounds. I take this gun to large MilSim's and can play just fine with the 7 mags I have acquired over time. I know this is alot of money to spend on a gun however, it is more realistic, more reliable than a AEG, and better performance right out of the box. This gun is amazing!

"This is an awesome rifle. I have the 416 which is basically the same gun. It has a nice kick to it, great accuracy and range and simple as heck to maintain. Keep it lubed and it works like a charm. Very gas efficient too, I can get 1 1/2 mags off a 10 sec charge. Fit and finish is spot on to the real rifle (minus trades) tho it does scratch easier than hard coat but I don't care. The thread is 14mm- which is a huge plus to me as all my flash hiders were for AEGs. Few cons include real steel grips DO NOT fit without major mods and the inner barrel is not snug in the barrel so a little ectrical tape would be needed, unless the ra tech barrel is larger. All in all this is the most fun you will have and probly dumps AEGs all together (I have) so with all that and mag compatibility across 8 different rifles you can't go wrong.

"I have had mine for a year now I think and I have beat the poop out of it, solid gun, nothing broke that was not my fault. if your mags are leaking you need to lube them, if not holding gas you need to purge them.

Great rifle for a great price, we have verson 2 mags so nothing should be leaking out of the box. gas guns user error is magnified.

Gun noobs need to reserch

"I've owned this gun for about a couple months now. I am not hard on this gun so its holding up pretty well. Its amazing how realistic this gun is. I mean that beyond the basic field strip. I watched a video on AR-15 assemblies and have found that the WE is very similar in construct, with the exception of the trigger assembly and how the buffer lock is secured. I currently have authentic Magpul (not PTS) handguards, pistol grip, and a mil-spec stock ( the buffer tube is indeed mil-spec). This gun kicks moderately, not enough to effect accuracy. The stock fps is relatively high (CQB incompatible). A $20 NPAS valve will fix that. The finish wears in any places where metal moves against metal (to be expected). Action of the bolt is smooth, bolt release functions fine when firing. However, bolt might not lock if simply charging with an empty mag. Also, if not lubricated properly, the loading nozzle might not ride back with bolt carrier completely. It will when firing, just not with charging. This gun requires maintenance and knowledge of the how the rifle functions and pieces together. This is not something to load green gas and play or oil up every now and then. It will require cleaning and lubrication constantly. This comes with the territory of any high end gas blowback. That said, I would recommend this gun, given the cheaper price and availability of upgrades.

Realistic action and breakdown
Good quality materials and build
Moderate kick
Real steel compatibility
Affordability (relative to other GBBR)

Trigger assembly is not steel (is metal, just not steel)
Polymer loading nozzle and flash hider
The flash hider is glued down but removable
Finish will wear after some use (to be expected)

"I've had this for about a year and a half. Did a few modifications and added a TBB barrel, Daniel Defense rail, mock suppressor, and Magpul furniture. This thing is compatible with my AR15 accessories which was really convenient.

-Awesome range (effective of about 60-65 meters)
-Durable (internals are top notch, no replacements so far!)
-Easily customized compared to AEG's because of the real steel compatibility
-Durable mags
-Blowback with bolt stop is a nice thing to have, which is standard on GBBRs

-Cost of maintenance and use (Gas, magazine valves)
-Magazines are very expensive and 32rds isn't very practical for airsoft
-Loud (impractical for airsoft)
-Magazines are heavy, you need a VERY high quality plate carrier and quality pouches
-Gas HOG

Overall: It's a fun gun, but be ready for high maintenance, a lot of money along the way, and you're gonna need to be a handy guy/gal to keep the gun and its magazines working properly. I enjoy that part though, because to me working on firearms is fun and this is good practice; along with the simulated recoil and 32rd mags.

I grew tired of this in airsoft, though. I was easily out gunned at times because of people with Hi-caps or midcaps higher than my mags, so I found myself suppressed easily, and I always feel bad asking for cover fire. It's very hard to suppress and shooting on full auto will just empty your mag's gas chamber like no other. Gas is also very inconsistent, making it hard to predict the bb's flight path past 150 feet or so.

Because of these issues, I've decided to sell this gun and all the mags (12), and use the money for a sniper platform.

Now that I have experience with this, I realized it wasn't for me. You might as well make it a DMR because there's just too many disadvantages going against 30rps AEG's or Polarstars with 200+ rounds in a mag. ***BE WARNED*** Having a GBBR is only for those who are very experienced and looking for a challenge.
