Picked up a 556 from Top Gun Supply last month. It has the fishgill hand guard like the ER but has the side fold stock, and the receiver looks the same as the classic model. I guess it is a "hybrid" model.

My initial impression with this gun is mixed: the internals show high quality, however, the furniture and the holo sight are just way too cheap for a >$1000 gun. I also noticed the play between upper and lower. However the play is almost gone if the bolt is locked behind so I didn't think it is a big deal.

Took it to the range last Saturday finally, 100 rounds through it without any problem (60 rds of PMC, 40 rds of wolf, both 55gr). The gun ran very smoothly, the recoil is soft comparing to my LE6920. I put a Nikon 3-9 scope on top of it just to test its accuracy at 100 yards. I was able to get satisfactory groups (definitely not sub moa, not expecting that either). Wish I had more time to shot it more thoroughly.

The cleaning is much easier than AR15, and I did not notice any wear on the BCG like someone described, no brass kiss either...maybe I have not shot it enough.

Overall I think it's a great gun, maybe a little overpriced but definitely a joy to shoot.

I agree I called SIG and told them that I shouldn't have to pay $300 for an aftermarket iron sight. They agreed and hooked me up with their rear diopter front hooded sight solution.

Guns are my work tools. I carry a SIG P220, and have a lot of time on a 551 and 556 SWAT. There is a huge difference between the 551 and the 556. Qality control wasn't part of the 556 unfortunately.

I agree. I had buyers remorse, but now that I have a good iron sight solution, I'm happy with it and am glad I made the purchase. A lot of AR models are going to the gas piston, but the piston is not as substantial as SIG's and they are overheating and binding and even bending. I've shot thousands of rounds out of the 551 and 556 SWAT and the piston is solid.

Enjoy

I have 1,500+ rounds through my Sig now. I have yet to have a FTF thats not mag related. With good mags, and ammo its 100% reliable.

For a rack weapon its as accurite as I can expect. Its not a bolt gun, but I can group with my friends Colt M4 and LWRC.


Mine has a little lower to upper play, and I still need decent iron sights. I had a bit of buyers remorse at first but now you couldn't pry this rifle out of my hands.

Sig customer service is great they called me 6 months after I bought it, just to make sure I was happy with my purchase and to offer me 20% off any accesories I wanted on their site.

Ditch the crappy furniture for the Swiss stuff and you will not be disapointed. These are fantastic rifle's when set up right! By "right" I mean like a 550, like the Swiss built them.

Congrats on your new sig.

If it means anything to you, I bought my Sig Classic for $1800, I had to return it twice for QA problems, I had to return both red dot and diopter because they were flawed out of the box.

To Sig Sauers credit they have been more than accommodating in getting my rifle and accessories to me in acceptable working condition. I still hate that I didnt know about the brass kisses until after I put nearly 200 rounds through my rifle on day 1. The fact that your newer rifle doesn't do this makes me wonder if they made some adjustments to avoid this.

Enjoy your new rifle and feel good about your purchase. At $1000 you have something far superior to an AR at the same pricetag. I've shot this and the extremely expensive SCAR and can tell you I rather use my SIG 556. My only personal regret is dumping $1800 on this rifle when I can get it now for $1000. ouch.

...the play between the upper and lower will vary from "gun to gun" to some degree...perfectly normal...this is also common with the Swiss 55x series...nothing new here...

...huge difference ?...in what way...the Swiss guns have their share of issues too...just like any other mass produced weapon...

...i wouldn't trade my 556 for a 551...and i have "just a little" experience with the Swiss guns also...

When I took my 556 pistol to the range I was having feeding problems. My new LWRC was too. I determined they were not getting enough gas pressure. The LWRC was stuck as I had nothing heavier that the, I think it was 90 grain 6.8 so it went back in the case. The Sig, however, "adverse setting activate." I burned through the ammo I brought problem free. When I went to put it back in the case, I noticed the receiver cap was unscrewed and fell off in my hand! Not cool. :evil:

When I took it home and stripped it, I screwed the cap back on as tight as I could and checked the piston. The piston was corroded! :roll:

I scotchbrighted the pitting and lubed it up real good and went back to the range a few days later. She ran like a top without having to switch the gas porting, but the butt cap came unscrewed again. :(

Overall, I feel it's a bit overpriced, the problems pissed me off and Sig is a no show on my emails which is the really irritating part. That being said, I don't regret buying it. It is fun as heck to shoot, now runs like a sewing machine and just needs a butt,,er,,plug, well, you know tool. The folks at the range were eyeballing it with lust too which is always fun.

I don't know if it's just my gun, but the extractor is pissed off! It tears the cases to the point I think they are unusable and throws them so hard they hit the divider to my right, fly up and ricochet off the divider to my left and hit me in the back. :shock:

I noticed when a hot case dropped down the neck of my shirt! :p
