Okay, my dealer just got my 556 today and I'm going to go pick it up Thursday night.  I have asked a couple of questions about what everyone is using for sights, but I just ran across an early ad for the rifle and they show a type of sight I've never seen before.

They list them as opitional on the SIG site, but I've never seen them before.  Anyone else?

I've heard from some of the fellas here about how much they like the rifle, but what about everyone else that own's one?

What do you all like about the rifle?  What don't you like?

I can't decide between the 556 or the Masada.

I just want to buy something.

I own a Sig 556 and an XCR, my choice by far
is the XCR. A Masada may too be in my future.

I owned both the 556 and XCR.  It was a tough choice, but I parted with the XCR.
I love my 556.  It is NOT as easy to dissassemble or clean as the XCR.  Also, you will need to make sure your optic rail is straight.
 I like the trigger and especially the right side mounted charging handle and ambi safety.  (I shoot lefty).
 Shoot it and you will see what we like!  Look forward to your range report.

So you can get into a rifle for less money and apply that savings to pick out the sights that work best for you and the optic you may choose.

i love my 556, i put a acog on it, i was a little disappointed about not having sights, but how many rifles on this websight actually use sights, execpt for back ups? i think that sig knew the people that would buy these rifles would be throwing optics at them it became my favorite rifle after shooting it the first time. i know all the guys on here that like these rifles stand the chance of being flamed by haters of these rifles, i guess to each his own

He is referring to Iron sights.  A lot of people use optics.  He is not saying we all just spray from the hip. Which is what I think you thought and why you would be mad.

i should have been more clear, mjohn got what i was saying. every rifle on this websight seems to have optics, and back up iron sights. i'm giulty of that myself. half of my black rifles have acogs' or aimpoints, ect... ammo is  to expensive for accuracy by volume these days

If I can find the e-mail I will post the reply...........I point blank asked them if a folding stock was in the offerings for the future, and the response was "we are looking into offering a folder for the SIG 556"..........when asked about the sights, the answer was "Yes, sights will be offered in the near future for the 556".........I told them that I would purchase one with the same features as the 550, and they acknowledged it and said "We are working on it"..........somewhat cryptic, but if it does away with the AR stock for a folder, and has some sights on it( preferably diopter, but I will take front and rear BUIS) and LEAVES the AR-15 mag capability, then I will spend some hard earned cash on one........

Those 55x carbines are more elaborate than people think to manufacture. The question is if SIGarms has the means and desire to put in the effort, dollars and man hours into building a 55x up to the same standards as the SWISSARMS products. Thus far the answer is no, and I dont see that changing anything soon.

I think they'd much rather throw out some poorly designed 556 for the idiots that have no standards and will buy anything SIG. Quick buck seems to be all SIG is interested in when it comes to a carbine

Yup.

Stamping dies are not cheap.

As much as I hate to say it, I don't really see them tooling up to make actual stamped 55x lowers.

We might get some kind of funky aluminum AR mag lower that uses the original folder. I won't buy one, but somebody will.

I'm holding out for a real 551LB with the stamped lower, original stock, and 55x mags. I don't care about the top rail as long as it's on straight. I have a feeling I won't ever see one though.

I have to agree as I kinda doubt we see the actual 551 either.............which is disappointing, as that is what I envisioned when SIG announced they were going to do a 5.56 rifle.........The original would be nice, but if we got the 551, but with the AR-15 mag well, I might consider one.........it isnt what I would have liked to have had from SIG, but I guess I could live with it........unless I decide to get the Masada and FN SCAR instead.

Ummm, okay well.........I had really hoped this would turn into a thread with people that actually owned the rifle would all participate in.  Instead, like many things here, it has turned into a bitch fest about what is wrong with the rifle, why it sucks, and why certain folks won't buy it.....or what SIG needs to do to it for certain folks to purchase the rifle.  

Okay, how about people that actually own one give me some feed back about how they like their rifle?  

Does anyone have the SIG factory irons for their rifle?  I noticed on the SIGARMS website it mentions them.

Where do you guys mount a sling?  Other than the two rails on the handguards I don't see any other place to mount a sling.  What have you guys used?

Initially I thought the stripping/takedown was difficult until I tried.  After the first time it is actually quite intuitive.

Does anyone own the SIG poly mags?  They look kind of cool and I was wondering how they work.

Here is some feedback from someone (myself) who has actually held and significanltly used a 556 and 55x rifle side by side.

1.  It is evident the 556 was rushed to market

2.  I don't think SIG found a corner they couldn't cut.  Cheap DPMS style CAR stock, A2 flash hider, no sights, cheap ass rail.

3.  Poorly thought out lower/grip/trigger guard interface.  I know it might not dig into your finger but it just looks like some afterthought job.

4.  Handguards are a joke

5.  Mag release sucks.  The gun was never intended to have straight insert mags and the mag release is too far foward

6.  Cheaped out barrel



It just doesn't have the same quality feel that a 55x gun does.  I would say the 556 is equavalent to a DPMS AR while the 550 is a Colt.

I guess "how about post if you own one" wasn't plain enough English?  Dude, it is obvious that you don't like it.

That's great.  How about you start your own thread titled "Why I don't like the 556"?

I'm not trying to debate why the rifle sucks.  I would like to hear from people that like it enough to own one.

I happen to own one.  I like it.  I would like others that feel the same way to offer me (as a new 556 owner) some feed back as to what I can expect and what they have experienced with the 556 they own.

I am not interested in the fact that you don't like it.  Or that you're not going to buy it because it is not a stamped receiver like the real one, or the stock doesn't fold like the real one, etc.

Reality is they won't build what you want.  That's life.  Reality is also that I'll never be able to afford a genuine 550 series rifle.  If you can afford one, great man, I am happy as hell for you.

i'm wondering how many people that trash this rifle have even shot one or better yet own one i was wondering what makes someone an expert on the 556? i actually own one, it's functioned perfectly, accurate, seems just as nice as my colt m4. i personally love the rifle, everyone that has shot it loves it, even a fud shot it 2 weeks ago and admitted it was a great shooter i can understand about have some quality controll issues that made some people raise eyebrows, that was horrible on sigs part, but they have made things right for the people that bought them. by the way at the ar shooting competion i shot in this weekend, a DPMS won oh the horror. no less than 16 ar shooters have shot mine and all agree that it's a well biult, accurate weapon. i'm sure the 556 isn't the best super duper rifle to ever come along, but i have enjoyed mine ever time i've gone out to shoot it, it's never failed, and my oldest son smiles when he pulls the trigger. that's all that matters to me
6/25/2007 4:15:31 PM EDT

My friend who purchased one said the same thing...........it is very accurate. I hope to get the chance to shoot it pretty soon. SIG did miss the boat on some things about this rifle, but I think that they are aware of what is wrong(judging by their response to me). The one I held at the gunstore was pretty nice, and didnt seem heavy at all to me........I will give SIG time and see what else they do to the 556, and see what aftermarket guys like Aurora come up with before I decide on it

You mean there are still people on here that offer constructive criticism?  I am shocked!

My first impression of the rifle has been that it is nothing if not solid.  Very little play between the upper and lower.  

I have only dry fired with snap caps, but the trigger pull is nice.  Very positive.

I find the rifle also points very naturally, and intuitively.

I do wish it had come with a sling, but I can get over that pretty easily.

SIG does their best to hide the 55x when the 556 is on display. The guns never ever share the same stage, and for a good reason. It becomes crystal clear how half-assed, poorly thought out, and thrown together the 556 is.

It isnt even because the 556 doesnt look like a 55x, but the fact the 556 simply isnt built well; not well for a SIG product, not well for a gun period. You would swear the 556 is made by century arms, and not SIG.

The fan boys just want people to STFU and say the 556 is great, but sorry, the product is not worthy of my dollars, or praise.


The biggest question that no one can answer is why didnt SIG just build what people wanted which is this. Had SIG done right by consumers they would be the darling of the gun industry. Instead, their reputation for legendary Swiss standards is all erroded

i've posted what i thought about mine in detail here before.  besides my generally positive comments, i just want to add one thing...

save the front retainer pin that needs replacing, this gun is VERY easy to maintain.  that's one area that an AR-15 fails miserably in, ease of cleaning.  sure, you can make an AR-15 work pretty easilly by cleaning some key parts, but to really get into all those nooks and crannies it is a royal PITA.  the sig doesn't have any of those nooks and crannies.  the bolt is extremely simple, and so is the gas tube.  besides that, none of the discharge gets on the bolt, the star chamber, the upper, or the trigger housing like an AR.

i hon't want anyone to shut up, it shocks me that there is almost a rage of hate towards this rifle. i have had nothing but positive experiences with the 556. there have been more than 20 different guys shoot my rifle, 16 of which are big time ar shooters. not one person railed on the rifle. even a fud(my father) admitted that it was accuate as hell and easy to shoot. i'll be the first to stand in line and complain if something went wrong with my 556. i'm only saying there are so may experts on this websight that have there own sig 550/551 to compair the rifles side by side too. i'm sure it isn't the super sig 550/551 that has a rock solid reputation. but my gun has been great, it might explode the next time i go out, only God knows that. but i enjoy it, and so do my boys. mine is well biult and soild, i wish i knew why all the experts hate this gun, so far it's all sounded like alex baldwin at the end of team america stuttering and saying rehearsed lines of what a pos this rifle is.

I'll totally admit that the 55x series are sexy as hell!  I suppose that since I've never even handled one, I have nothing but ARs, AKs, and XCR, etc. with which to compare.  

I will still say that it feels like a quality rifle.  

Until it proves me otherwise, I will continue to think that way.

I apologize for having come off a bit snappy.  Sometimes I fail to realize that everyone has their own opinion.  I may not agree and think that you are wrong, but that is fine.

I've had only good experience with mine. It feels well built and it's accurate. The hand guard isn't the most amazing feature, but it's not like a standard AR guard is anything to get too excited about.

I recommend it to anyone who doesn't immediately try to compare it to what they've heard a 55x is like. I have no idea what a 55x is like because I've never handled or shot one before. I'm sure they're great. Judging the 556 based on what it is, I can say that's it's a solid gun that's just as good as any of my ARs (none DPMS by the way - one Colt).

3.  The switch to MIM internals

i hate to sound ignorant but what are the mim internals? i didn't realize that all sig products where so bad i have a gsr 1911, excellent pistol and extremely accurate, my oldest son has a mosquito, he enjoys shooting it, runs reliablely on mini mags, i do admit the trigger is horrible, the 556 has been great rifle for me, i could do without the tapco looking stock, but that's easily fixed. i do agree about the rainbow colored pistols, i saw one at a gun show that made me laugh. i'm not being a smart@ss when i say that i didn't realize that sig had so many problems, i bought a p220 made in west germany many years ago and it's been the most reliable /accurate(besides the gsr) pistol i've ever owned. i know many guys that have sigs and swear by them also. i have many of there products now and have had great luck i guess, never needed the service center so i honestly can't comment on that end of sig. i guess what i'm getting at is i don't understand what makes the 556 so bad, i don't know anyone that owns one that doesn't love it. even the guys that are on this website that own them, like them. i'm honestly not trying to keep sturing the pot, and as posted about everyone is entitled to there opinion. but there really seems to be hate for the 556, after shooting and owning one i don't understand that i guess. well i guess to each there own

Man, you just had to go and post that pic.................I got to handle one of those a while back with the shorter barrel, and it was pretty sweet.........That's the one I think alot of us lust after, and the one I would give anything to possess, only I am poor....

I came pretty close to purchasing a SIG GSR until I started hearing some of the problems associated with it, which lead me to the Kimber.

As for the MIM question, if I am not mistaken ( and someone please correct me if I am wrong), those are metal injection molded parts......And I think some people have had issues with breakage of these parts.

I would still like to see something along the lines of the 550 hit these shores, and if it somehow came to pass, then I would probably be in line to grab one..........

I've had a 556 for a couple of months now, but today I'm getting rid of it.  When I first got it, it was shooting really well and would shoot ammo that my AR's did not like.  I shot it at an indoor range and was getting nice one hole groups at 25 yards (the max yardage at the indoor range)  Then a few weeks ago, I noticed that I was getting a white substance around the front lug area of the receiver.  I thought maybe it was the Hoppes #9 reacting with something, so I cleaned it up and put the rifle in the safe.  When I got it back out, that white "corrosion" was back.  I cleaned it up again and went to the range and shot the rifle.  Still the rifle performed well although I didn' t put any rounds on paper, just steel shooting and general plinking.  I then took the rifle home, didn't clean it this time, and put it away for a couple of weeks.  In the mean time, a friend of mine had just purchased a 556 and asked me if I had accuracy issues with my 556.  I told him no, and we met this last Saturday to figure out why his 556 wasn't shooting very well.  At the outdoor range, we had 4 really good shooters each take turns shooting my friends 556 and mine.  To my surprise, both 556's wouldn't shoot!  Our target was set at 25 yards and non of us could get a group under 1 1/2" from either 556.  We were shooting Wolf, military green tip 62gr, Federal 69gr match and some reloads that were his special match reload for his AR's.  I can't remember what scope he had on his 556, but mine had a ACOG.

After the range session, I opened up my 556 and that white "corrosion" was back!  I emmidiately took it to the gunsmith at the store where I bought the gun and had him look at it.  In his opinion, the white corrosion are bluing salts that weren't killed off and when I shoot the gun it heats those salts back up and they started to grow.  He had no idea as to why the accuracy has gone south.  He saw my groups when I first bought the gun there at his shop, so he knows at one time it shot well, but now, who knows.

Needless to say, I'm not too happy.  And am waiting for the manager of the store to get back from vacation today to see whether or not he'll trade me out for another AR or not.  If not, I'm taking it to another gun shop and trading it.

As for the corrosion, it looks like this issue has come up before, as I've noticed on my friends 556 that SIG either blued the front lug better or "painted" it with something so it wouldn't corrode anymore.

I also think my friend is going to get rid of his 556 as he is not happy with its accuracy either.

I've had a 556 for a couple of months now, but today I'm getting rid of it.  When I first got it, it was shooting really well and would shoot ammo that my AR's did not like.  I shot it at an indoor range and was getting nice one hole groups at 25 yards (the max yardage at the indoor range)  Then a few weeks ago, I noticed that I was getting a white substance around the front lug area of the receiver.  I thought maybe it was the Hoppes #9 reacting with something, so I cleaned it up and put the rifle in the safe.  When I got it back out, that white "corrosion" was back.  I cleaned it up again and went to the range and shot the rifle.  Still the rifle performed well although I didn' t put any rounds on paper, just steel shooting and general plinking.  I then took the rifle home, didn't clean it this time, and put it away for a couple of weeks.  In the mean time, a friend of mine had just purchased a 556 and asked me if I had accuracy issues with my 556.  I told him no, and we met this last Saturday to figure out why his 556 wasn't shooting very well.  At the outdoor range, we had 4 really good shooters each take turns shooting my friends 556 and mine.  To my surprise, both 556's wouldn't shoot!  Our target was set at 25 yards and non of us could get a group under 1 1/2" from either 556.  We were shooting Wolf, military green tip 62gr, Federal 69gr match and some reloads that were his special match reload for his AR's.  I can't remember what scope he had on his 556, but mine had a ACOG.

After the range session, I opened up my 556 and that white "corrosion" was back!  I emmidiately took it to the gunsmith at the store where I bought the gun and had him look at it.  In his opinion, the white corrosion are bluing salts that weren't killed off and when I shoot the gun it heats those salts back up and they started to grow.  He had no idea as to why the accuracy has gone south.  He saw my groups when I first bought the gun there at his shop, so he knows at one time it shot well, but now, who knows.

Needless to say, I'm not too happy.  And am waiting for the manager of the store to get back from vacation today to see whether or not he'll trade me out for another AR or not.  If not, I'm taking it to another gun shop and trading it.

As for the corrosion, it looks like this issue has come up before, as I've noticed on my friends 556 that SIG either blued the front lug better or "painted" it with something so it wouldn't corrode anymore.

I also think my friend is going to get rid of his 556 as he is not happy with its accuracy either.



Blueing salts and other finish medium are not corrosion.

Don't waste your dealers time with SIGs problem.  If you are unhappy, you should be dealing directly with SIG.

Just got off the phone with SIG.  The guy told me he'd never heard of the white "corrosion" and after I pressed him a little more, he put me on hold to go ask one of their gunsmiths.  They said the white corrosion is normal, that it just means the gun is drying out and that is not bluing salts, because they nitrolon the guns.  They told me to use CLP to get rid of it.

I asked them about accuracy and he couldn't tell me.  He gave me some story about how he shot a 1 inch group without sights at 7 yards the other day.  I said that's all fine and dandy, but I can't get the rifle to group under 1.5" at 25 yards.  I asked about what ammo they use and if they did any accuracy testing.  He said they just shoot them to make sure they function.

All in all, I felt I was talking to someone who didn't have a clue.  I think this rifle is going bye, bye!

What serial number did you get?  Mine is 2062.  I am wondering if yours is newer or older.

Every problem I have heard with any Sig 556, the serial number has been less than 2000.

In one persons problem, with a finish color. Sig told them they changed some stuff at serial number 2000.

That person sent their rifle to Sig, and Sig fixed it up nice for them and they have been happy since, I believe.

My problem wasn't the color, it was what appeared to be corrosion and the accuracy going south.

For those of you who have 556's, what kind of accuracy are you getting?

Like I said, we were hard pressed to get 1 1/5" groups at 25 yards!  If this was the case at 100 yards I would have been happy.

Double check your mount.  Someone else with an Acog reported horrible accuracy on Sigforum.  Turned out the less than spec rail and non-flush screw heads were screwing up the mount and it was not solid causing accuracy to go down the toilet.

556 @ 50 yds w/Triji 4x: 5/16" (that's just under 1/2", also best group of the day). Fiocchi 55 grain...5 shot group.

Mine is serial numbered 1117.

I think it's a great gun and was more accurate in my hands than the XCR.

However, nothing is perfect.  It went back for a canted rail--twice.  The rail is now straight but picky about the ARMS #40 sight--everything else I have tried works well on the rail.  They also replaced the bolt hold open, as it was INOP from the factory.

Mine has the two tone finish, and I really like it.

The factory stock, while not the best quality, is comfortable and functional.  I like it and will keep it unless it breaks. Is it ugly?  yes.  But form follows function, and once I used it, i knew it would stay.

Hand gaurds are a bit wide, but strong, fairly tight and just enough rails for my purposes.  The wider base helps for sandbagging.

Iron sights?  Who cares.  If I ever feel the need to add more weight to my rifle, I'll buy some aftermarket ones.  

I have had no problems with this rifle from round number 300-- at firstI had a few failures with some norinco and guat ammo, and it also choked my AR and XCR.  I have 1500 rounds through it now, and it's been smooth, accurate sailing.

people talk about MIM parts being bad, but no one was willing to pay me more for my S&W 686-2 when i sold it, but you hear lots of complaining about their new guns and the MIM parts.  I bought a new smith and have had no problems.  Money talks.

SIG556 @50yrd with Mk4 scope.  4 - 5" 10 shot group.  62grn FMJ  ser# > 2000

AK 223 @50yrd with iron.  2 - 3" 10 shot group.  62grn FMJ

AR15 @50yrd with Mk4 scope 1.5" 10 shot group. 62grn FMJ - (used as reference)

All shots fired at bench rest.

With wide range of accuracy reports, clearly, SIG has some QA & QC issues with their manufacturing process.  Case in point.  Two brand new SIG556, ser# only single digit apart.  One has longer top mount than the other which prevents removal of front hand guard.  The other was fine but mount is canted.  Both mounting screws not flush.

Both SIG function flawless in throwing lead down range.  Not a single jam noted.  Excellent in spray and pray situations.  Have noted AK 223 are decidedly more accurate than the SIG.

SIG does their best to hide the 55x when the 556 is on display. The guns never ever share the same stage, and for a good reason. It becomes crystal clear how half-assed, poorly thought out, and thrown together the 556 is.

It isnt even because the 556 doesnt look like a 55x, but the fact the 556 simply isnt built well; not well for a SIG product, not well for a gun period. You would swear the 556 is made by century arms, and not SIG.

The fan boys just want people to STFU and say the 556 is great, but sorry, the product is not worthy of my dollars, or praise.


The biggest question that no one can answer is why didnt SIG just build what people wanted which is this. Had SIG done right by consumers they would be the darling of the gun industry. Instead, their reputation for legendary Swiss standards is all erroded

Do you own one or have you shot one or have you been reading on the internet?
Provide anything other than the flapping of your gums to hold up any of the semi-retarded shit you spout and the rest of us would be happy to listen.



As far as quality, mine is flawless, every part perfectly machined and it runs perfectly from the first shot it has had no malfunctions of any kind, it is accurate and has a great trigger.  It was ran by several LEO's and a couple of SF guys and me and we all enjoyed it.  There are a few guys who will be buying one in the future as well.

So given the choice of listening to another internet gob, flap his gums or actually shooting the product  and letting professions try it out, I am going to have to stick with my experience.

Hopefully, you can mow enough yards this summer to buy a gun of your own.

Why don't you go to the SHOT show and find out for yourself how they are displayed.
