Agreed, for the price I've seen them go for I may give it a shot (headed to some gun shows this month) if I can score one for under $850 I'll bring it home and tell all of you about. Granted Sig has a few not so good pistols but I've owned a few of their products and couldn't be happier. I even bought my dad a 1911 tac-ops for father's day and that thing is amazing.The "improvements" sure do look interesting. They don't tell you much in the form of specifications. I noticed that they point out that the lower receiver is of 7075 T6, but they make no mention of the upper. I wonder if this implies that the upper is made of something else. 6061, perhaps? I also wonder who's making those barrels and what they're made of. The swivel attachment points are pretty cool though.
All in all, I'm with rcmodel on this one. I've been down the road of owning one of Sig's new releases before and it's the reason that I haven't owned a Sig since then. The name Sig really meant something at one time, but these days I'm no longer willing to take it on faith.
Looks like this is Direct Impingement rather than a piston-based AR.
From what I understand, that would be OK if they kept it clean diligently.
Not sure if DI is more accurate, due to less moving parts.
I guess they are bucking the trend of piston ARs.
They are bucking nothing. They came out with the 516, which is a piston AR, before this one.I guess they are bucking the trend of piston ARs.
A couple years back I was talking to an Iraq vet who told me the military was all switching to piston.
And then I see all the piston guns coming out. That's all my opinion is based on. Mine is a long piston PWS.
You are correct.Mea Culpa, and I am happy to have my opinion updated and changed. Just that based on stuff I've read regarding AR actions, it was my understanding that DI is much dirtier because the gas directly blows back into the gun, while the short and long pistons don't actually let the gas directly back in.
With DI you occasionally clean the bolt, with piston you occasionally clean the gas block and piston. There's no free ride with a piston AR.Mea Culpa, and I am happy to have my opinion updated and changed.

I agree. Want a piston? Buy an AK. The AR was built around DI, it's just the way things were meant to be.What trend?
DI is good, and what the rifle was designed for. Buy a quality rifle, use decent ammo, use good mags, keep it lubed, and it should serve you well.
Lacking many of the superfluous bells and whistles often found on new AR-15s, the SIG Sauer M400 is a straight-shooting, lightweight carbine ideal for most any application.
I agree with you on that. If I can pic one of these up I'll only be changing the hand guardsFrom the article
Fancy way of saying that even though you are paying the same price, you may still be replacing the stock, grip, and handguards. That said, it also has bells and whistles that others don't (ambi mag release and built in QD points). I wish they would have gone with mid-gas with the 16" barrel, but it is still a competitively priced rifle. Academy has one for $900, with the superfluous MagPul furniture and sight.
