"I purchased the black/SBR version, for my first AEG. The primary reasons are that I own an actual Sig556, and that the closest venue for playing is a CQB facility, so I wanted something nice and compact. So here goes. Please bear in mind that I don't have a lot of basis for comparison with other AEG's so far, having only played with a few different models so far.
The SG556 by Cybergun/Swiss Arms is an excellent piece of kit. Its weight and feel are just like my real one. As another reviewer noted, there are a couple of minor differences with the real firearm. Specifically, the charging handle significantly different, as is the blade in the front sight. The rear flip-up sight is pretty flimsy, and not exactly the same as the real firearm's sight. That said, it's pretty flimsy on the REAL firearm as well, and I replaced it before I ever even took the thing to the range.
I don't believe it comes with a MOFSET, and it would be frankly amazing if it did for this price point, but I haven't had the reason or opportunity to tear apart the gun yet to get a good look at the internals. Even so, the stock trigger response is pretty nice, and it has a reasonably good ROF in full-auto. I matched it with a Evike's 1.5x30 red/green dot sight (which I'll review separately), and a couple of 6mmProShop M4 mid-cap magazines. So far, the magazines function and fit perfectly in this gun, and have the added benefit of being pretty inexpensive. The one I purchased seems really battery efficient as well, compared with the other AEG's I've played with. I'm very glad the pic rails are all metal, because I feel as if they offer a lot more stability than polymer pic rails, for any optics or accessories are mounted on them. I'm entirely satisfied with my purchase, but as with most things, there are a few things that could be improved. Please don't take the following as reasons not to get this gun, because it really is great. They're just minor quibbles.
The manual is very brief and offers very little information to the buyer. In fact, in the case of this particular piece, a lot of the information it contains is outright incorrect and applies to a different version of the SG556 AEG altogether. It notes that the battery is located in the forward handguard, but it's actually located in the adjustable stock. No diagrams of internals, or instructions for disassembly or maintenance are provided. Some of the instructions contained are unclear, such as the instructions for adjusting the hop-up (accessed by pulling back on the charging handle). Mine came with the hop-up bucking adjusted to the minimum, so it needed to be turned up a bit, which is accomplished by simply turning the adjustment in an upward direction.
While the pic rail on top of the upper receiver is solid as a rock, the forward rails/handguard section wiggles just a bit. I suspect I'll be able to fix that with a bit of minor shimming, but until that's done, I'd avoid mounting a laser on that part of the gun, because I wouldn't trust it to provide a consistent point of aim. It would be fine for a flashlight though.

"My family plays airsoft. Me, my wonderful wife and our 4 children ranging in ages from 10 to 20 (3 boys, 1 girl) We are a family that enjoys hobbies and this is one of our favorites. My daughter bought this rifle last week and we were finally able to get out and give it a run on our own woodsball field. We spent about 15 minutes admiring her newest purchase and shooting it at the range. At 8.5 pounds, it's beefy to say the least. Weight aside, I was impressed. It shot straight and fast. The trigger response seemed pretty crisp and it felt comfortable seated against the shoulder. We then spent the next 3 hours blasting the hell out of each other, lol. We traded weapons occasionally and I was able to run her gun for 2 rounds. AMAZING!! What a gun. I was engaging targets at 65-70 and making solid contact. The weight was never a problem. No feeding issues. No issues at all.
Pros
Tac driver
Range
Sturdy feel
Quiet
Could easily be converted to DMR
Mags feed well
Price
Cons
It's heavy but not unmanageable
Battery compartment is located in handgaurd, not in the stock
That's it... This gun rocks (held its own against my son's Krytac lvoa-c)

"Had it for about a week and a half, and was able to take it out for some simple plinking to see how the hop up, trigger response, and handling was. I was very impressed with all of the above.
Pros:
- Trigger response was very good with a 7.4v and 11.1 20C lipos.
- Hop up unit was very accurate dialing it in with my elite force .25 gram bbs.
- Full Metal heavy weight. (Can be a Con) Feels extremely robust.
- Good rate of fire with both the 7.4v and 11.1 v lipos estimated 20 rps.
- Shoots hard with .25 gram bbs. Estimated 360 fps with .25s.
- Very Ergonomic and is ambidextrous.
- Very nice Tan Paint job and the dark earth polymer furniture matches paint perfectly.
- Takes many M4 mags, mag well is too tight however for both g&g hicaps and midcaps.
- Feeds flawlessly
Cons:
-Heavy (Can be a Pro)
- Pistol grip seems a little creaky at first but I tightened down the screws and problem fixed.
- Smaller battery compartment can only take stick, peq, and small type lipos. (Wired to handguard.)
- Limited rail space on handguard.
Overall I was very happy picking up this gun. I love Sig guns and I like how unique and functional they are It will be a perfect out door field gun!

"Overall, I am extremely pleased with the gun. Running a 2S lipo, the gun has a quick trigger response. The rate of fire is a bit lower than most AEGs, but that is to be expected for a gun with a longer range. The longer barrel makes for a longer accuracy range as well as an effective range.
Someone mentioned below that there were no threads for a mock silencer; there is a small set screw in the bottom of the flash hider that has been glued in. If you can remove this set screw, then you should be able to remove the flash hider and replace it. The other alternative is to replace the outer barrel that is attatched to the front sight assembly. To do so, a press fitting must be removed before the outer barrel separates.
Appart from the new outer barrel, a Magpul PRS stock, and swapping the wire leads to Deans, I have made no other modifications to the gun. Perhaps I will upgrade my gearbox later on but I am content with the performance as is. The SIG 556 is an excelent gun for someone looking for a decently-ranged rifle, while maintaining a budget. Had I the $$$, I would hav bought the King Arms SG556 except it costs $450.
5 of 5 because the only modifications I made were personal preference, not manufacturing errors.
Quick note: the description of the gun states that it uses a long-type motor. This is incorrect; the gun runs on a mediom-type motor.

"Just received it!
It is very realistic and good looking. Nothing else to say, it's a must have.
On the other side, the orange thing was a pain to remove and on the box says that it has a 14mm thread for silencer but I can't find it

"I got this gun recently and let me say the pictures evike has do not do the gun justice, first off the gun (at least mine) is black just regular m4 mat black not the grayish color in the picture. Next the gun is also a lot slimmer then is seems in the picture also the similarities of an m4 give it a familiar feel when using this gun making it ideal for almost anyone.
Pros
High fps
Not an m4
Very multi purpose , (sniper, assault rifle, heavy gunner)
Rof~ although its lower then most guns the fps balances it out
Very realistic
Cons
Heavy
Iron sights aren't ideal , the rear sight has a filter that is very small ( a dremmel can open up the hole and fix that problem)

"I've had my eye on this gun for some time, and when it came back into stock, I bought it straight away. I am pleased to say, it is everything I could have hoped for.
Pros:
Mostly metal, the rest is high quality ABS plastic.
Shoots hard (exact FPS unknown, I'd say above 400 with .25's)
Spare mags are fairly easy to find.
Heavy (good, in my opinion. I'm a thin guy, and I still am able to pack this around with relative ease.)
Great feel.
Highly accurate.
Looks great.
Cons:
Difficult to put battery in (takes some practice, and no quick in-game battery swaps. You better have someone cover you if you need to do that.)
Slight mag wobble, nothing significant, and you can barely notice it.
One of my mags has issues feeding, might be a lemon. I have a spare mag, so no big deal.
A bit long, you might want a side-arm if you are going around tight corners.
My opinion, one of the best guns out there, especially considering the price. Buy it, and you won't regret it.

"I got this gun last week and it's great. The mags hold 300 bbs each and one of mine came broken. However it was an easy fix. It's compatible with all echo 1 m4 mags and magpul emags .
Pros
6 inch grouping at 50 feet
two mags
stock can be removed for CQB
flashhider has counter clockwise threads for tracers and mock suppresors
460 mm inner barrel( 6.07) diameter
Cons
8.5 pounds
rear sight is terrible but can be fixed by opening up the hole with a dremel
Other
can easily be modified to blowback by attaching a rod to the piston and charging handle
If you are looking for a DMR or woodland gun this is it. Extremely comfortable and very good grips

"Got this gun last Monday and used it last Sunday and love it!
everything you want in a realistic airsoft gun is here, full metal gun, high cap clips (400) and comes with 2 clips!
this gun is a beast, I mounted a x3-7 scope and fired full auto at about 70+ feet and the BBs hit spot on with video game accuracy.
if your looking at this.. buy it!

"The best gun I have ever had. I highly recommend purchasing this gun!!
by Timothy H. on 12/13/2011
"I'm so glad this gun finally came back in stock.I was worried this was discontinued forever. It's a beast! I added a red dot and a sling to it and BANG I'm keeping up with $400 guns on our field. It's a great gun for little money. Very accurate, good rate of fire and a well built gun. Something that doesn't look like an M4 is a great plus in my book. Says M4 mags fit but I haven't had much luck they're usually too loose. I use Sig mags. Never a problem with them. The battery compartment issue people have is only confusing for the first few times you open it. After a few charging sessions you'll be able to open in seconds.
Pros:
NOT an M4
hits hard
good ROF
Great bang for your buck
Cons:
Iron sights are useless. Get a red dot

Great accuracy and range
380+ FPS

great gearbox
14 mm threads
400 round mags
Full metal lisenced receiver

"Out of the box this gun is quite able.
420 out of the box for mine, rof is average but the power more than makes up for it (I stick to single fire)
My favorite thing about this gun, just the pure size, feels amazing to just hold!
Took forever to find one, I got lucky ha
Iron sight is pathetic, but can be improved by removing the small screw holding a small piece of iron to it (still not too reliable BUY A RED DOT)
Pros
High fps out of the box
Size
cons
Average rof
Iron sight is useless
Small piece of plastic on tip of bottom grip comes directly off :/ (cannot see piece in picture, its located at top of the bottom grip when you unhinge it to plug in the battery)
Ps. does anyone know if m16 stocks would hook up correctly on the back of this?

"what kind of screw is on the barrel if there is one?
by Andrew A. on 04/03/2010
"ok this is just as good as it gets, great accuracy, high fps, and most importantly a great price, this is probably one of the most efficient-for-cost guns on evike. A great buy, but the only thing that might turn buyers off is, like paintball, it's a completely made up gun model. This factor is so small that it doesn't matter though, it's all about performance and boy does this gun have it.
