Mine is JT012xx. I bought in Jan 2010 and shot about 600 rounds. No sign of abnormal wear.


Finally got enough rounds through to check my JT004XX purchased in 2010. 500 rounds and looks perfect, thankfully

In case anyone is still tracking the serial numbers, here's mine.


Interesting that we are both JT004xx, but have totally different wear as I have no signs after 500 rounds. I would imagine these guns were assembled from similar parts within weeks of each other. I guess every one is somewhat different.

Just passed the 10,000 round mark through mine. JS019XXX.

Still the tack driver she was out the box.

When taking apart my gun for the first time, I noticed some grease on the grooves of bolt carrier and inside chamber.

While cleaning the gun this grease was removed. I did use gun oil, but should I put any grease back in any areas?

Hello Everyone,

I just finished reading this thread and it literally took my breath away. My SIG 556 rifle is out of the serial number range that seems to be having the problems and is still unfired as I bought it as a project gun in lieu of some other firearms projects. It was my intention to make it my "go to" gun for self defense, but now plan to put it in the safe as a shooter for the range ONLY given the abysmal support SIG has provided in responding to this problem. I refuse to rely on a weapon that I cannot count on the manufacturer or a gunsmith to provide reliable support to. My loved ones count on me to protect them, and I take that trust very seriously.

Does anyone know of a top notch gunsmith who specializes in the SIG 55X series of rifles?

If so, please point me in their direction.

Otherwise, this will remain my one and only SIG product to be used ONLY at the range.

- Anthony

If your 556 is in the safe and never fired, how do you know it is unreliable?

I have two that have fired over 8,000 rounds and both are perfect, as are both of my friends 556s have thousands of rounds through them without a hiccup also.

I would not worry about a problem until after you have a problem....just my $0.02.

Irregardless of by who or when a pistol/rifle/knife was built. If you are worried something breaking during a "time of need", then you should possess the knowledge to correct the issue. If a main spring breaks in a 1911 during your "time of need"; Do you Fed-ex it back to Colt or will you ADAPT?

I strongly agree with Skypup and Nittany Lion . Prepare it per Ulie's instructions, then by god use it. Having a malfunction or stoppage is going to happen, understanding how to correct it as well as recognizing what the cause was is vital to improving your skills. Although my 556 is in the range of problem rifles I DO NOT have any problems associated with what's alarming posters.

2 556's

serial # JT 0004XX

serial # JT 0130XX

no wear or damage at all.

I acquired them both used, and they most certainly will continue to be used.

Serial No. JS027XXX. This is quite disturbing. Over on SIGforum there is a lot of discontent with SIG quality lately. This is only one more nail in the coffin of a once very fine company. I will see how they respond.

I do not know if I am just lucky or if Sig made some changes but my 556 has over 2000 rounds under its belt and no problems :D . I purchased it a year ago july. Ever since reading this thread I have been watching for a sign of wear but to date nothing

Probably most 556s are good, but a few rifles in every batch have a problem. You no doubt got a good one.

Hey Guys, I have less than 500 rounds through my rifle and I have "ejection" marks. That is about it though. My rifle # is JS 032***. Have you guys heard anything bad about this serial number range? I did have to get it looked at by a gunsmith already due to cycling issues. Turns out Sig put the gas regulator on wrong. What do you guys think?

I spoke with SIG today; they have already sent me a return label. I'll keep everyone posted. So far, I cannot complain about how they have handled my concerns.

What you guys have to realize, is that you are worrying and complaining over nothing. This is the reason SIG is not taking the problem seriously. It's because they feel it is NOT a problem. As far as causing accuracy issues, I do not believe that is possible either, regardless of what was posted here.

This is a normal wear and tear issue for this particular weapon. I have never seen a weapon system nitpicked like I have the SIG 556 series.

No offense to anyone, but this is my opinion on the matter, and the opinion of most 556 owners, to include SIG themselves. A small minority complaining about a tiny wear mark on the bolt carrier that in no way shape or form effects function will never be taken seriously by SIG.

As far as accuracy....3-4 inches at 100M is AWESOME for a combat rifle. Even 4-5 inches is acceptable. I crack up when I hear people complain about their 3-4 inch 100M groups out of a combat rifle.


:arrow:

You have got to be kidding 1 to 1 1/2 moa should be the max !
These are civilian, military looking, semi autos. They should be capable of this kind of accuracy with the right bullet. Sixty two to 77gr. bullets should be used in a 1/7 twist and 55gr. are quite capable with this twist but not as accurate.

I'm not sure if this wear is anything to be concerned about or not. Serial number is JS0250XX. It's a 556 Classic with a date of January 27 2009 on the case.

It shoots 3-4 MOA (10-shot groups) with Prvi 75gr Match ammo from the bench. Not as accurate as I'd like, for sure, but not as bad as some have reported.

You're using the right ammo!
It should do at least1.5
