Gas tubes are an integral part of the AR-15/AR-10 platform and there is no reason to skim on quality here. All the tubes listed are made out of 304 Stainless and are either in a plain finish or given a black nitride finish.
If you are wondering if I shipped
your package, the answer is yes. I have ZERO reasons to not send your
package out. If I printed off a label, I can confirm to you that it was
sent out.
No, the tracking doesn't work, USPS
is backlogged worse than a heroin addict sucking down bananas. The
tracking number you have is the one that may eventually work. USPS
issues are readily visible on the news, you can confirm what I'm saying.
Sit tight, your package will come. It's going to take a bit, but it will happen.
