"This is really a awesome replica, after installing a npas in the bolt and fielding it at my local cqb arena I am pretty happy with it. Honestly the magpul mags are the better option as stated in other parts of this site and on the net. The fill valve in the stanag style magazine are the TM style valves that allow gas to spill out as your filling it so they cannot over fill, this is awesome when you have a japanese airsoft gun like a tm or a wa. Here though the system is a little lack luster and causes leaks, that is a different issue seeing as this is the kit and no magazine is included so I digress, Once I got done scratching my head and swearing at the instructions for telling me to put the full auto sear in after the fire selector (watch johnjayrambo on youtube he has a video on how to build a lower receiver) the kit went together very quickly and easily. Basically if you can lace your boots and consider yourself semi competent this is going to be pretty straight forward stuff here folks. As soon as I was finished assembling the whole thing I loaded a magazine and let it sit for about 5 minutes, then I slapped it in the carbine with a satisfying clickity clack noise that is very reminiscent of handling an actual firearm. The first time I shot it I was extremely pleased that it actually worked, not only did it work it is the coolest airsoft gun I've ever seen or used. G&P's WOC is so much fun to shoot and handle, it is extremely finicky though so expect some experimenting and fine tuning. Definitely not a platform for just anyone though, but once you put it together and get a couple of suckers out with it you will feel like a Jedi master.

"I just received this kit today and finished within 4 hours of work.

Building this awesome kit was very entertaining and very educational, since i work as an airsoft technician and this helps me understand how m4 gbb work.

Dont expect this kit to work smooth when you finish asembling it, it needs some sanding and LOTS of oil to help the gun wear itself to make it run like it should... remember this is a challenge kit, its supposed that you make some effort putting this together as it should, once it starts running smootly well.. i just gotta say i fell in love with this thing.

Mag efficiency is awesome, holding enough gas for about 80 rounds.. mags take 39 bbs each.

Things to get as MUST, are Hammer with bearing, Sear, Buffer Lock, Bolt catch , all of them made from steel, since the ones that come with the kit wear down easily because they are made from aluminum.

I havent field tested it but overall i would definetively recommend this.. Man id even buy another one just for the fun and challenge of building it!

"I have recently purchased this kit and it is very awesome, after 2000 rounds the only thing to break is the buffer lock, and a steel replacement is only $10 so I can not complain to much. If your are wary of getting this gun because you have to build it DON'T BE!!!! It is extremely easy to put together and I have a very en depth step to step procedure of how to put it together

Pros.
Easy to assemble.
Two nozzles, one for 300fps and another for 350fps.
Solid construction.
Cons.
Upper and lower receivers may be wobbly against each other, however it varies, in one of my kits the upper and lower meet very tightly and then my other kit has a pretty sloppy fit.
G&P Pmags will need modified to work in the gun, either modify the gun or the mag catch, again this video can be found on my you-tube channel if you want to know how to fix this.
Overall
Great looking gun and after you get the mag or mag catch modified it works like a charm! I have nothing but absolutely great things to say about these kits. If you are on the fence about getting one of these kits do it! They are only a fraction of the cost of a assembled one, plus if you put your gun together to start with you will better understand the weapon, and be better able to fix and maintain it in the future.

"I got this gun a few days ago and its awesome. It took me about 2.5/3 hours to put it together ( I accidently messed up putting the outer barrel on and I couldnt get it off.) Anyway: I didnt recieve a pin to put the auto hammer lock in, the buffer lock broke immedately and the mag has problems. As far as the provided pmag, the bolt gets caught on the black rubber valve on the magazine. Despite those things its a great gun and im sure its fun to shoot (didnt shoot it yet). Also, if your worried about some assembly or any peices they were different than in the picture and in the videos we all watched on youtube: The bolt was COMPLEATELY assembled *woot woot* no need to assemble the nozzle, the buffer is wayy different, rather than a speed buffer or silver solid one, its a black one with a hole in the middle. Lastly, the hard hop up bucking everyone complains about is rubber, super super soft rubber.

Pros:
Cheap
Awesome
Easy to put together
Magpuled out
comes with a magazine
full metal
new pieces

Cons:
No auto hammer lock pin
buffer lock broke (upgrade to steal immedately)
magazine valve needs a replacement

"i love this gun. it took me about 2 hours to build and everything went together perfectly. mine came with an oversized bolt and after about 2 months evike finally got me a new one. mine shot over 425 fps with .25g bbs right out of the box and that was awesome. it is super accurate, im hitting targets upto 200 feet away. it works great and is really gas efficient. if you want to get this then you really need to. i cant say enough how great it is. the cool part is that this comes with a magazine. and its the G&P PMAG, which is actually full metal, but im not upset. its 10x better than the LM4 mags. its super easy to put together, and worth every penny.

pros:
shoots 425 fps with .25g bbs
full metal parts
realistic to a real gun
operates flawlessly
is just awesome

Cons:
it shoots 425 fps with a .25g bb


thats not a bad con but for those that want this for cqb try using heavier bbs or get an NPAS kit for the gun.

"Let me start of by saying that this gun is a very nice gun. For the price, it simply cannot be beat. I own 2 of these and have assembled and used a 3rd. All of these are amazing quality except for some crappy pot metal parts. the buffer lock broke on 2 of my rifles, the bolt catch assembly falls apart soo after (on both) and the hopup will break aswell. al of these parts are relitively cheap to replace with good quality one. Once thats out of the way, these guns are great fun. they shoot hard, far, and fast. I would recommend this kit to anyone. It really isnt as difficult to build as it may seem. A little technical savy and this thing will be running in 2/3 hours!

PROS:
hard kick
good rof
great range
high fps (feild)
great external and internal quality (mostly)
WA parts and support

CONS:
some parts need replacing immediatly
high fps for cqb (may need an npas or something)

FPS with green gas is 430-400 with a .25g bb, though settles to 350 with a .25 for most of ma

"EPIC I love this gun. Im 14 and this is my first GBBR this took me 2 days to assemble i didn't want to rush it. its fairly easy if u have the right tools witch i did . when its fully assembled it has a very nice wieght not to heavy not to light. I'm very happy it came with all the parts and a few extra. the hammer assembly is a pain in the butt but it can be done. and when its done your gonna one a sick weapon. i had to to some serious breaking in before it started to chamber the bb on its own other than that this gun is a 10.


pros
every thing about it
hard recoil
loud
sexy
beast
400fps with .20
magpul
intimidating

cons
absolutely none

get this gun and with a little elbow grease you will have one sick weapon.



love it.

"This is a very realistic and super high quality rifle. However, they weren't kidding when they called this a challenge kit. There are only 21 steps, but almost every single step involved quite a bit of frustration. Some smaller parts needed to be filed down to fit property. The instruction was a photo copy of a photo copy, so the resolution was terrible. There was not much writing in the instruction, only low quality pictures. Double and triple check every step before you put the parts together because the fit is extremely tight, and it will be a pain to undo some parts to correct your mistakes. But once this gun is assembled, it is absolutely amazing. The realism is the best in the business. Everything is metal. The recoil is strong, and very loud. This gun comes with a steel barrel tip as well as a plastic orange one. Do not ever take this out in public without a gun case. Do not fire it in the back yard if you have neighbors around. You are just asking for trouble. I have used both propane and duster gas with great result. The duster gas would be perfect for indoor use as it does not smell, and the velocity is lower. But don't forget to use silicone oil if you are not using green gas. There are some build videos on Youtube that are very helpful, especially one made by a guy name Jedi.

"here is what I've experienced the build kit is nice and easy to understand how to put together if you have basic mechanical skill the exterior is built well I was missing the barrel all together but I called evike and they had it shipped to me Pronto so good service evike thanks now back to the gun it has a break in period once assembled so don't get butt hurt if it doesn't run like you want but once I broke it in I went to the nearest field and really put it through its paces. The stock bolt and bolt catch were worn out after play, the mag catch broke and extensive wear on the trigger group parts. Now keep in mind this is a build kit so if it's not perfect replace parts, there are parts that I would get that are made out of steel are the bolt, bolt catch, mag catch, ( trigger group eventually) buffer lock.

OK
Pros
Good base for a butt kicking custom build
Teaches you (know your rifle)!

Cons
Patience lots of patience
Break in period
Lots of tweaking
major operating parts need to be replaced with steel aftermarket parts
Not skirmishable right after being put together (BREAK IT IN!)

"A great gun a little shaving and filing required but overall easy to assemble the one complaint I have is that I got a matrix hard kick buffer and didn't realize it until I shot it and it broke my buffer catch
by John N. on 08/13/2015
"Like the other reviewer I recieved this kit missing a few parts and the whole outer and inner barrel. I called evike and they are currently looking into it. Will update this review once everything is solved. Thanks.

"Just picked this up from the Evike Warehouse yesterday. After the long drive home and cracking open the box, I had found the first piece on the instructions was missing. Along with that there was various bolt, springs, the barrel, the inner barrel, and many more pieces missing from my box. Not really sure how this was even allowed to be handed out. Will be making the journey back to the Evike Superstore tomorrow to try and address this issue.
