"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.
"I have only just received it 2 days ago, but so far I am happy with this gun. It has some weight to it, heavy in the hand, but solid. Nothing came loose, no bad suprises very tight. the selector swich is very tight, i used some silicone on that as well as when you pull the stock, its very tight. It seems very realistic. Normally when I get A new AEG first thing I do is clean the inner barrel. It seems to me that A new barrel, fresh out the box is VERY DIRTY , most times, not so on this one, it was clean. The FPS is I believe what is advertised. The motor is not putting out A great ROF, but it will do, probibly will upgrade that in the future. So far its realistic, no surprise out the box , and is fun to shoot, accurate The rotory hop up is fine. I got she shorter model, and its exciting so far. hope this helps. CL.
"Finally got to use this gun all day for indoor cqb
Out of the box I think the gun performs great for what it is and what it costs! All my M4 mags fit the gun except for my 2 A&K 60rd midcaps. The gun was extremely accurate and I was able to hit many targets through very small swindles and cracks. ROF isn’t the craziest but we were firing semi only anyway. The body is full metal and feels great. I’ve gotten a lot of compliments on the gun. Hop up is rotary style and easy to adjust.
My two complaints about the gun thus far:
The selector switch doesn’t really seem to lock into place. You’ll hear it click but it’s so easy to accidentally turn it. My biggest gripe is the stock. On mine the buffer tube is loose. If i screw it all the way in, then the stock points sideways. It’s not hard to be playing a game and suddenly you hit your stock the wrong way and have it wobbling around on you. I’ll try replacing the buffer tube, but as it is i can’t get my stock to be tight AND in proper position.
