Looks like we've still a few quality issues with the Sig. I've been seeing posts alledging 556 gas tubes launching down range but no actual owners posts to the effect. Therefore paid it little mind. This morning I'm stripping my still unfired 556 down to send it out for a barrel length reduction. In the process I pull my gas tube out and what catches my eye immediately? Slag near a weld towards the knurled end of the tube. A closer look revealed a hairline crack/void in the weld itself. Well it does not take much of a stretch to imagine what would happen should that weld fail under load/gas pressure. A tube launch perhaps? Maybe something to the rumors eh? Needless to say I e-mailed Sig customer support this morning and will at the very least get a new tube out of them I hope. I was putting the lower and other parts from the stripped upper back in the hard case for storage while the barreled upper is out getting the deed done to it and I run across the QC/QA tags......too funny. Yeah, if only.

Re: SIG 556 Owners Check Ur Tubes

Can you take a picture of the crack and post it here?

Re: SIG 556 Owners Check Ur Tubes

I took snaps and sent em to SIG. I'll post em in a while. You can see the slag but not too clearly the crack. Maybe I'll shoot it again, the cams zoom is washing it out.

Got a fast response from Sig customer support. In an e-mail recieved this morning the tech said they are sending me a new one. Thats pretty damn good service I'd say.
