Gotcha, my buffer's attached with a 1/8th hex head screw. I use a key tool so as not to put too much torque on this screw. A dab of grease on its threads should hold it tight with no more than a snug hand tightening.

Awesome pics - my buffer is definitely a different color than the one in the photos.
I called Sig today and explained the issues. They sent me a return label and RMA number, so back to New Hampshire she goes.
I also noticed a small gouge in the cam pin track of the upper receiver just behind the steel insert. Also, the manual says the recoil rods should be pinned, but they are not on my carrier assembly. There is a small bit of wear on the firing pin retaining pin as well.
Sig quoted 3-4 weeks turnaround so hopefully all will be fixed.

Yeah, my recoil pins aren't pinned either.
Sent back my rifle today after talking with SIG CS. He was super helpful and took down notes. He quoted around 3 weeks. I believe SIG is trying to make everything right. They want you to be pleased with a reliable rifle. I really hope all will be fixed.....

This cam path upper gouging is an issue with all piston driven ARs. I have 4 AR piston uppers and they all have it. In my SIG516 with 100 rounds, it's a small wear mark, and 516 with 1,000rds, it's a gouge along most of the cam path. PWS AR10 shows the same wear.
I've recently, as well as a bunch of fellow Sig Talkers switch all my standard cam pin to POF's Roller Cam Pin. This roll pin provides immediately smoother action you'll notice with your charging handle, and almost no upper receiver gouging. Sorry if I sound like a POF salesman, but these are pretty neat tricks
Another point of confusion is the new Carriage Assembly's recoil spring rod's plate. Yeah, the original Dec 22 '16 recall flier did describe these rods as pinned into the end plate, and not a removable part. BUT, that's not what has been installed with these new Carriage Assemblies. There is NO change to this plate, and the rods are still just snapped-in.
So, be very careful when reassembling these recoil spring rods into this plate, to make sure both rod ends are securely snapped into place!!
Also, should mention that I've sent MANY guns back to Exeter - many times. I own ~20 SIG pistons & rifles, and can think of only 1 or 2 that haven't made at least one trip back to NH - although there are several that have made >1 trip too. Heck, my local Fedex folks probably think I'm the state patrol's armorer or something!!
It's probably my combination of frequent range times, and perhaps being a little OCD too. But it's nothing to worry about - They usually return these guns in better shape than I sent, and on a faster turn-around than I expected...
