ICS SiG 552 'Commando' Review

SiG 552 ‘Commando’ by ICS - A Review by Yosser

With a reputation for quality AEG’s produced by ICS expectations were high when this latest offering landed on my doorstep.

The package this comes in seems to be a break from some of the more traditional boxes we see from the cheaper Chinasoft range (not ICS of course), without the usual line drawings or just names on the front box lid. The front has full colour pictures of both types of the SiG552 in either ‘SWAT’ (full length) or the ‘Commando’ (shortened, carbine) models. It proudly announces that it is manufactured under official licence from SiG Arms, Switzerland and the box is manufactured to be a one size fits all solution for packaging both model variants in.

Opening the box, the SiG sits nicely in its red plush/velour effect carton/plastic base along with cleaning rod and 2 ICS Clear High-cap magazines. The battery is supplied separately and does NOT come supplied with the AEG.

Looking at the SG552 in more detail it is obvious to see the benefits of the licensing agreement that ICS have hammered out with Swiss Arms, with full trades marked onto the full metal body of the AEG. I’m not sure how long these trades will last as they don’t appear to be embossed so they may well wear off over time (something to think about if you like to keep your AEG’s as ‘models’). The only obvious ABS plastic parts on it are the folding stock, fore grip and the 3 RIS rails mounted on the fore grip as well as the ‘pistol grip’. The body (both upper and lower receivers), muzzle end and sights are full metal. The sights are your typical H&K Diopter type (not to every ones taste, but I like them) – these look adjustable – but not sure how useful this is in Airsofting terms. The foresight also has a flip down element blade, which I think is for reduced lighting conditions and has adjustment. The body is grey coloured whilst the rest of the AEG ABS plastic parts are Black. The body also has a cocking bolt on RHS which locks back to reveal and adjust the enhanced cylinder style hop up unit (which I’m told is typical for ICS). The bolt (see skirmish report) is released by pressing the bolt release catch (also metal) on the LHS of the receiver. Firing selector is ambidextrous and is metal. The trigger guard folds, to allow those with MASSIVE fingers to pull the trigger, or just those with thick gloves. In order to use the body mounted sling points you will need to add a metal ring to be of any use and whilst I’m at it I think they missed a trick by not adding a body mounted RIS rail for red dots etc.

The two parts of the receiver come apart easily for cleaning and maintenance. Removing just one front end body pin (which you can push out with a little force) then open up and remove the fore grip (you do just up to this part to replace battery). Press the ICS Logo button near the stock end on the upper receiver and the top receiver should slid away to the front. The top section holds your barrel and hop up unit. Whilst the lower holds the gear box etc. just be careful not to trap any wires going to the front fore grip section when putting it back together.

The stock on this AEG is solid. Really, really solid. You could say it was more solid than a solid thing that went to the school of solid and then graduated from the University of Solid. No wobble, what so-ever! Press the button and fold the stock around (to the RHS) and lock in position to its latch on the receiver body. It takes quite a tug to get it off, just watch you don’t catch anything when you lock it back in position. Just wondering if this is going to last after a good few skirmishes though (might be just my paranoia kicking in).

Although I’ve yet to have this AEG apart, from the blurb it features :
Metal gear box,
Metal bevel gears and metal bushings fitted as standard.
Turbo 3000 motor
High Quality silicone wiring loom

The battery in this AEG sits in the fore grip section, which on the Commando version is a right pain to fit. It’s a tight fit, trying not to trap and pinch any wiring and getting it to go back together. I wouldn’t like to replace this in the middle of a skirmish. A 3 point large battery pack sling probably wouldn’t go amiss here.

The magazines supplied are 2x300Rd clear plastic type and are of good quality
(which you would expect from ICS). I liked the clear aspect of the mags and the facility to clip them together like the G36’s was excellent. One fully wound mag seemed to empty upon firing without further winds (just need more of them now).

All in all I would give this AEG 8/10.
I have a few small gripes but nothing too major and its build quality is excellent. It scores highly in looks and feel but its skirmish-ability I feel is let down by a small battery.

The AEG was purchased from ZeroOne for £285 which also included a ‘downgrade’ to a One Joule spring which FPS’d to around 302 on first chrono.

Good quality and finish
Quality manufacturer
Spares readily available.
Clip together magazines
Solid Folding stock – great for woodland and urban
Light weight despite metal parts
Nice touches such as bolt release catch and trade markings

Fitting the battery is a big pain in the arse
Should have had body mounted top RIS
Easy to drop mags if your not used to the magazine release catch by trigger – easy to catch on webbing etc.
Trades will probably wear off.

Skirmish Update:
The bolt handle came off in my hand! and I couldn’t adjust hop-up for a little while before realising it just slots back in (Doh!). I need to check this doesn’t get lost in future events. Also lost the mags a few times whilst trying to dodge air strikes and caught the mag release catch without realising (thanks to Wolf for finding them!).
The range on the so-called enhanced hop-up seemed disappointing – but this could be down to a number of factors – new gun, needing to ‘bed’ in, poorly adjusted hop or undercharged battery. Time will tell.

ZeroOne will only guarantee it for use with an 8.4v battery and the one I got was only 1100mAh – so only really lasted for 2 full auto games. Really needs a larger battery. Don’t think I would like to be changing it mid skirmish (although it is advertised as quick change, I find it fiddly at best).

Things I would change on the AEG apart from the battery which I’ve already griped about. These are really small items like full metal front end RIS to replace the cheapo plastic ones and add a metal RIS rail along the top receiver for the addition of red-dots etc. Otherwise, I’m happy with this RiF and would definitely recommend this brand to anyone starting out in Airsoft – although they are expensive, as they say you get what you pay for and people have said it should ‘last’.

[8 Stars] out of 10 RECOMMENDED

    Hey there, I've read the integrity of your review and I have quite a bit of questions for you ;) .

    - Can you fit a 9v6 in there, I have the TM version and I can't fit a 9v6 battery but it is said that the ICS version has more space :) .

    - Did you test its range, in feet ?

    - How's the rate of fire :D ?

    Thanks for the review mate, I'm waiting for my ICS sig 552 to come :O .

  2. Unknown Said,

    Sorry you can't fit the 9.6v battery to it. The front hand guard is too small, but the gear box if tough enough to fit a Lipo - still trying to source one myself. (You could fit a large batt if you use either a 3 point batt sling or a PEQ)

    Range & ROF are so subjective and dependant upon spring battery etc thats why I've not posted them.

    Thanks for the comment and rating let me know how you get on and if you find a bigger battery etc.

    Whats up dude. I just bought the ICS SIG 552. It's pretty sick, but I haven't even fired it yet as I cannot fit the battery I was sent. What was your solution? (other than a battery box)I'd like to preserve the classic shape of this gun, so a bettery inside the foregrip is key for me. How is the accuracy. Also, did you ever find out if the internals would support a LiPo? ICS's website seems to suggest that, although its kind of hard to tell. Rock on homie.

    Posted on April 1, 2009 at 2:10 AM

  5. Unknown Said,

    If you ordered a battery from the same supplier for this AEG I'm assuming it's the correct one, so should fit! The fitting is difficult and you'll just have to persist I'm afraid. Try putting the 3 cell section in the bottom section of the foregrip and the four cell section in the upper part. I understand what you mean about not wanting to spoiling the classic lines. Still hunting for a lipo which research shows the gearbox should be up to as it's re-enforced. Good luck and enjoy the SiG. See the ICS battery guide on this site.

    For your information, I'm the same guy as post 1-2-3 but not post 4.

    To be honest, I'm afraid to try out the Lipo battery... just can't take the risk, plus I'm not a ROF freak. I still didn't receive it, its coming directly from Taiwan (or wherever ICS is situated) because there aren't any stocks holding this gun in my country yet.

    You suggested a battery separated in two parts , where the heck do you get those type of batteries (or are you talking about Lipo batteries) ?

    Good luck with the AEG when you get it. You'll enjoy it I'm sure. Suitable battery like in this link. http://www.component-shop.co.uk/html/body_7vp1400afp-ll.html

    I use one - it's not easy installing but it seems the only one I can find until I source a LiPo.

  9. Unknown Said,

    I was just giving you a guide as to what does fit - can't say for the one you linked to - the width of each cell section of 29.5 looks a little wide to me. If you try them please let me know if they fit easily. I'm sure other SiG552 owners would like to know. The battery fits over and under the barrel in the forgrip - it's a tight fit.

    Hey, I had a quick question about this gun. First of all i just bought one before doing a lot of looking. I'm glad to say i like it a lot, but up grades are hard to find. I see what you mean about the battery problem but most of all the RIS is weak. So, would you have any ideas of where to buy rail additions or a new non plastic front grip? Thank you, Trent.

    By the way, why did you downgrade your sig ?

    Posted on April 11, 2009 at 5:41 PM

  15. Unknown Said,

    The SiG was 'downgraded' to a 1 Joule spring as I didn't want to wait for the bedding in process of the spring. Our site limit is 350FPS - brand new they tend to be a little hot. With a 1J spring it was 'guaranteed' to be less than this. Last test it came in approx 310-320ish

    Posted on April 11, 2009 at 6:48 PM

  16. Anonymous Said,

    The original ICS SiG comes with an M120 spring which corresponds to about 1,5 joules (395 FPS), and that is exactly why I'm getting the ICS version of the SiG 552, usually I always upgrade my AEGs to an M120 spring.
    If 350 FPS is your FPS limit then I presume that you play CQB matches, right ?

    Posted on April 11, 2009 at 7:48 PM

  17. Unknown Said,

    Yes at SWAT Urban it's pretty intense CQB action. Most site limits in the UK tend to be around the 350 mark anyway - so I can use it anywhere (some sites maybe lower in CQB 320 etc).
    Check out some of the vids.

    I have a 'short' TM mag but I can't say it feeds that well. The ICS ones are much better and larger capacity. I've yet to see any of the 'fake' Ammo TM ones here in the UK yet. Please let us know how you get on with them.

    Hey I'm not the same guy as post n.19 but the fake bullet TM mags seem to double feed on the ICS sig 552.
    Hey I've got a question, did your ICS SiG 552 come with trademarks, because mine didn't.

    Posted on April 21, 2009 at 8:57 PM

  22. Unknown Said,

    Yes in the UK it comes with full trades. The pictures on this review are of my SiG552 and you can see the trades clearly. Not sure where your from but possibly the manufacturer may have issues with trades in the USA etc - not sure. Unless you have an early pre-production model? Thanks for the info on the TM 'fake' bullet magazines.

    I have to say though, that I'm disappointed with this gun.
    Firstly the fore grip moves front and back.
    Secondly it double feeds often.
    Thirdly it didn't come with trademarks
    Fifthly the cocking lever slips off if you release it and let it slap against the gun.
    Sixthly I can't even get an 8.4V mini in it.
    And finally I tried the Lipo 11.1V and it screwed the fire selector up: when on Semi it shoots burst or it works as though its in safety mode.

    Posted on April 22, 2009 at 4:06 PM

  25. Unknown Said,

    I can only comment from my experience with this AEG and it has been mostly positive. I've not had any problems with the fore grip - But fitting the battery correctly is a huge problem. As for the cocking lever It's supposed to be able to come off but this easily? As for LiPO thanks for the tip. Sorry your experience has been as positive. Is it possible you have a very early production run of this AEG?

    Posted on April 22, 2009 at 4:36 PM

  26. Anonymous Said,

    I don't think I have an early production version of the gun because I ordered it later then you.
    I got it from my local shop, and he gets it directly from ICS, I asked him to check with ICS for the trademarks to see if its normal for where I live not to have any.
    When the cocking lever slips off it doesn't slip off completely.

    One more question, does this 552 accept the TM top picatinny rail or will it be a difficult fit? I already am quite set on it if not for the conflicting reviews, but I do like the overall looks of it, just hope that I don't end up with a lemon.

    Posted on April 24, 2009 at 6:38 AM

    I've no idea about the top rail, I've been trying to find one in the UK in stock. When I get one I'll add it to the blog.

    Not sure I can help on this one, never encountered it myself. Is this a double feed issue? You should be able to do a google search as I've come across other websites which cover that. Otherwise sorry no idea (ensure your using good quality BB's and you fully wind your magazine as this should empty it being ICS!

  35. mike Said,

    There's one question I need to ask you: at the front of the rifle, is the fake gas tube twistable. If it is, then it should pop off and reveal a phillips head screw, which when removed allows the front sgiht assembly to be removed. You don't have to remove it, but I just need to no if the fake gas tube moves in as clockwise direction. To do so, depress the button beside the fake gas tube.

    Posted on June 30, 2009 at 2:17 AM

  36. mike Said,

    Another thing after reading your skirmish report. If the front sight assembly is removable, you can buy a full metal front handguard that has four rails on top, bottom, left, and right. You can also buy a marui scope mount for twenty buck off airsplat or ehobbyasia (preferably ehobby). The RIS handguard will run $45.99 without shipping, and shipping will range from 9-19 dollars (for me it did, and I'm on the east coast and that's farthest from Hong Kong). The 552 is much more modular than people may belive, and ICS is coming out with some new accessories to make the 552 into a DMR. Check their main site.

    Posted on June 30, 2009 at 2:27 AM

  37. Unknown Said,

    not sure which direction the fake gas tube turns but looking in the manual the full front end comes off as you said. The accessories look awesome on the ICS website thanks for pointing them out.

    Posted on June 30, 2009 at 9:03 PM

  38. mike Said,

    Darn it, I forgot to ask you another question. Is the flash hider removable, too? If so, is it a counter clockwise thread? Sorry for so many questions.

    I asked a similar question above. Since the front sight assembly is removable the way it is on a Marui or JG, then, in theory, the ICS 552 should accept any airsoft 552 RIS.

    This is not something I would do to my 'precious' SiG 552!

    hello mate:) I have a couple of questions...

    how long does the battery last?

    how long would the bbs last if u use semi auto/auto for a 3 on 3 match?

    Posted on March 28, 2010 at 12:02 AM

  46. Unknown Said,

    Hi Dan,

    All your questions are quite subjective - the answer is 'is it depends upon the battery size & your skirmishing style' - lots of full-auto will deplete the battery quicker.

    From a 1100mah batt. I get about a half days skirmish (maybe a little over) with a good mix of full auto action.

    As to how long a mag of BB's will last? - I can empty a mag in about 30 secs on full auto with a Lipo battery! so that depends on what your doing!

    Hope this helps.

    I'm sure a JG SiG will do just fine for you but will prob need upgrades if you want to run LiPo's etc. Its quality will not be upto ICS's but if you look up Flankertankers review in Youtube you should get the info you want. My ICS 552 is still going strong and costs about 285 UKP from Zero One in the UK. Let me know how you get on with the JG - I'd be happy to post your review of it here.

    I've just picked up my 552, straight out the box it is a very solid gun. It's ready to run 7.4 lipos and give an rof of around 15, these also fit inside the fore grip. Had the spring changed as it was running hot at 395 - 399 fps, now at 344 - 349. All in all an awesome bit of kit. Already added a fore grip handle and suppressor and got a top rail in the post.
