"Well, as the name states, this is a "Challenge Kit." that should not be taken lightly. As others have stated there are no instructions in the kit to tell you where everything goes, but lets just hope you've taken apart more than a few airsoft before trying to put this kit together.
It can be tough.
But if you know your way around airsoft guns then it shouldn't be too bad. I got mine mostly together within a few hours. I had to wait on final assembly as some of the parts I put on this gun had to be ordered in. I didn't really have a doner gun for all the other parts needed to build a full rifle. But in the end, I got it all together and it is a neat gun that gets noticed a lot at local fields. People always have to look twice at it. Recently someone said to me about this gun, "It's like an AR, but with all the disadvantages of an AK." And that's kind of true.
The hardest part about this gun is getting it to feed all AK style mags correctly. At this point I have most of the cheaper AK mags fitting and feeding properly. This gun hates LCT mags for some reason. Both Hi-caps and Mids. It seems to prefer the cheaper CYMA mid-caps. And I'm OK with that!
One of the weirder parts of this kit is the two piece hop up unit. You have to fully assemble it. Including the screws that hold the two halves together. Remember, everything needs to go together, nothing comes pre-assembled. Have a flat file near by and be ready to make small "adjustments" to make things fit. Have a few spares of different things like screws and other small bits. All the unique parts to this gun come in the kit, but you will have to supply a few odds and ends to make it all work together nicely.

******BIG WARNING!!!!!*****
The lower receiver is made a bit thin in spots. You may have build other AR type guns or made mods to those bodies, but with thi body you need to be gentle and tap lightly while fully supporting some parts. As was stated by another reviewer here, putting in the trigger guard rear split pin is one of these spots that needs extra love and attention. That area is easily damaged and cracked. I wish that area had more material around there to help support it better. I ended up using a small screw instead of that pin because the torrances for most of the holes are extremely tight. In a lot of cses I needed to either open the hole up slighting using a small round file or a flat file on the pin passing through the body to get thing to fit without damaging the body.

In the end everything fits and it now works very well.

A couple of pointers:

1) the hop up unit uses a lot of the inner barrel inside itself. This is good because it helps support the barrel, you will need a longer barrel than you think. I used a Lonex 14.5" outer barrel which should take a 363mm inner barrel in a normal AR set up. In thi case to get the inner barrel all the way to the end of the outer barrel I used a 407mm inner barrel length. Again, that's OK with me!

2) And the trick I found to fix the feed issues was to use a thin rubber O-ring around the part of the hop up unit that fits inside the gearbox shell. It spaced out the hop unit to allow better feeding of more mags. It was a super simple and easy fix. Just nothing too thick. You just need a couple millimeters of space to achieve great feeding.

Over all, I'm pretty happy with the kit. It makes for a very unique rifle that not a lot of people have.

"This is a bit of a pain to put together but I accomplished it with no instructions and no online tutorials. Very solid and very unique. For a person like me that has a huge Boneyard of parts I was able to assemble basically everything I wanted except for a few custom touches out of the scraps from leftover guns. I didn't really have any issues with anything fitting but perhaps I just got lucky in that department. I ended up going with a G&G gearbox full of aftermarket goodies a Noveske rail and unknown outer barrel. Everything fit well although I did have to source a couple parts that were supposed to come with it, and ended up receiving two selector switches instead of one for some unknown reason. Fortunately everything that is specific to the SR 47 was included.

The one con I will give it was finding mags that fit. None of my lonex, nor any other magazines I happened to have lying around would fit, not so much fit because they fit in the mag well but wouldn't feed. G&P mid caps do the trick just fine and are all I run in the gun now, the only other gripe relates to the mag well as well it really need some type of block off plate at the top of the mag well otherwise you really have to focus to get the magazine in, it's not a quick Mag swap on the field.

Other than that I have a beautiful custom rifle now that stands apart and I am very happy with it

"Okay, so I got this trying to find something really unique that still uses V2 gearbox parts. And I certainly got that.

The Good:

A nice black painted finish with good logo paint as well.

All parts to convert from a normal M4 are included.

A very nice unique look.

The Bad:

This almost certainly will take modifications to get everything to fit properly.

The Ugly:

Absolutly no instructions included and no tutorial online.
This was extra hard for me because of simple things such as the bolt release and which way the dust cover pin goes and little things of the sort.

Overall a great buy. There's not really anything else like it. I get complimented all of the time and it has a super aggressive look with the Centurion Arms 12" rail (the one that is really slim and uses their own system) and a suppressor.

I'm afraid that this won't be availabe for much longer seeing that it's been on the Epic Deals list and the price keeps dropping, so get it while you can!

Review From Booligan Airsoft.

Introduction: The SR47 is one of the most rare weapons both in the real world and in the airsoft world. Before, if you wanted to make a replica of your own, you had to purchase the Hurricane kit which was both hard to find and was very expensive, costing over $400-$500 normally. Well, Evike has made the process a lot easier and more affordable with their new "SOCOM 47" challenge kit. This kit is much more affordable than the old Hurricane kit and comes with pretty much everything you need to convert your M4/16 type AEG into an an AK magazine equipped hybrid. This will be a brief review, discussing the basic info on the kit, some installation tips, and some pros and cons, but for detailed installation instructions, watch my video which follows over my shoulder as I built the kit.
The kit was sent directly to me by Evike, who has it available HERE, priced at $120.00 currently at the time of this review. Evike also sent out a G&P 8mm ball bearing equipped gearbox, located HERE, priced at $70. The kit is designed to be used in conjunction with a complete M4 or M16, so if you are planning on picking up just the kit and a gearbox, you will need to purchase an outer barrel, rail or handguard, iron sights, buffer tube and stock, pistol grip, trigger guard, as well as an AK pattern magazine.

Kit Information:
As mentioned before, this is considered a “Challenge” kit, which means that you have to assemble everything basically from scratch. Thankfully, all of the small parts are packaged in their own individual bags making assembly pretty damn straight forward. The kit includes the upper and lower receivers, special hop-up unit (without inner barrel, bucking, and nub), pins, selector switch assembly, charging handle and faux bolt, dust cover, and magazine release assemblies.
The receivers are made out of metal and are quite well made, with only one real noticeable defect in my example. On the upper receiver, where the charging handle locks in place, the material was cast quite thin, causing some barely visible holes. This is purely cosmetic and is most likely isolated with my example.

Another little quirk with the kit is actually how tight all of the tolerances are. The charging handle is difficult to pull back and requires a slight push with returning it forward due to how tight everything is. Also, to adjust the hop-up, you need to physically pull back the faux bolt to access the adjuster which is located further back than normal.
There are trademarks on both sides of the receivers that are nicely engraved. Most of the trademarks are Evike specific, and there is a unique serial number located on the left side of the magwell.

Installation Tips: To help you build your own, I put together a video watching over my shoulder as I built mine. That video can be found at the top of this review.
A few notes of my build process:
Assemble most of the small parts first, such as the dust cover, AK style mag release, hop-up, charging handle, faux bolt, etc. Some of these parts will require a small amount of super glue, especially the plastic guide for the faux bolt.
Plan on the main body pins needing a little "motivation" to get into place firmly. This is due to the tight tolerances of the kit, especially once the gearbox is installed. I actually had to mount one of my pins in the opposite way to get it installed.
My kit included two selector assemblies, and I used the red colored one. Not sure if there's any difference between the two, but red is better, so there.
The G&P gearbox that I used in my build was, for the most part, a top notch piece of equipment. 8mm ball bearings, steel gears, and great air-seal out of the box. I had to open it up in order to convert it from front wired to rear wired, and saw that it was very well lubricated and shimmed. However, once I actually built the gun, I had some firing issues, some of which I'm still working on. Semi-auto is a little "crunchy", requiring a very stiff trigger pull. I'm not sure if something in the cutoff lever area is out of whack, but it's an issue I'm still working on. Also, the spring on the anti-reversal lever is quite weak, and the bevel gear only has two notches for it to interact with. Because of this, I would get occasional "rollback" between shots, so I swapped out that bevel gear and AR latch for different steel units, as you saw in the video.
Performance wise, it's shooting very consistently in the 360 FPS ballpark. Rate of fire with the JG motor I installed is pretty good, considering the mid-level output of the LiPo that I'm using. The new hop-up unit puts great backspin on the BB, allowing me to use heavy weight ammo with ease. I was worried about air leaks since the hop-up unit is kind of a clamshell design, but it actually has great consistency.

First really affordable SR47 option
Full metal construction
Installation is pretty straight forward if you've ever worked on an airsoft AR
Individual serial number
The included hop-up unit is very well constructed
G&P gearbox that I tested is quite consistent

Slight casting defect on my upper receiver
Tight tolerances make hop-up adjustment tricky
Some magazine wobble
My G&P gearbox required some work before use

If you're looking for an affordable way to build your own SR47 based replica, this kit really is the way to go. At $120 for the kit, you just need to add your own M4 AEG and AK type magazine and you're ready to build. The kit is well made and comes together quite easily with a minimal amount of drama. For detailed build instructions, check out my build video at the top of this review.
