After a couple thousand rounds I still have not gotten mine to choke. It eats literally everything I can feed it and spits it out with authority. It flings brass 15+ feet and just keeps on running regardless of what I can find to load the mags with.
The backup iron sights are pretty cheap but they will work in a pinch. Plan on buying some better irons if you are going to really rely on them. The plastic stock and handguard can feel flimsy, which I think is what turns most people off during a first impression. I put on a Magpul UBR stock and Swat quad rail and that made all the difference. Now everything is tight and solid, it feels like I could use this rifle to jack up my car if needed. The stock trigger is excellent with an adjustable secondary pressure point so you can get it setup to your liking.
Some people report excellent accuracy out of the box, but I unfortunately did have to struggle through some accuracy issues. After trying many different things now the gun will shoot about 2” when cold with good ammo at 100 yards, haven’t tried to improve it with hand loads yet. I have also noticed the POI will wander as it warms up, but then it seems to stay at one place one warm. It is also sensitive to pressure on the forend as you would expect since the barrel is not free floated.
It is a little nose heavy but installing a set of 551 handguards makes a huge difference on the balance of the rifle. I don’t mind a little extra weight and enjoy how smoothly it shoots, nicer than other AR’s I have shot, it has less muzzle rise and is faster back on target. The short barrel 556 rifles are over-gassed, they need a smaller orifice in the gas block, so I am guessing that is where the extra felt recoil came from that one poster reported.
About the only thing I would trade my 556 in for is a LWRC. I have fired my buddies 14.5” LWRC M6A2 in 6.8 SPC a bunch and it is a very nice rifle. I know there are plenty of other great makers out there as well but the LWRC accuracy and overall package has impressed me the most. The stock trigger is terrible, and it doesn’t seem to cycle as smoothly as my Sig, but it is much more accurate and of course also runs great.
I have spent about as much as a nice AR to get my Sig 556 where I like it, but I feel it was worth it. It’s too bad they didn’t make it correct out of the box, I think they would have had a real winner if they hadn’t hampered a great design with some cheap accessories. Sig is having a $300 rebate on the 556 rifle right now, so combine that with great prices from places like Topgunsupply and you could get a nice rifle for dirt cheap.

Brett,
Nice Sig!!!
They must be extremely reliable.I haven't seen one post complaining about that issue.
Guys,
I'm glad your AR-15's are running good.Honestly I've seen plenty of them jamm before in 3 gun matches and in service rifle shoots too.
I checked the gas key on mine it's GTG.Checked for the M4 feed ramps,nope,so I got out the dremmel tool and created some along with a high polish.I got new Magpuls coming.Soon I'll see if it's more reliable.
