AR15 Gas Tubes

What are the pros and cons between melonite and stainless gas tubes. And has anyone used or any input with Aero Precision Gas Blocks.

Parkerized or anodize or chrome a choice? At first thought I’d go for stainless.

Stainless is the gold standard. That said Melonite has come a long way in coating application and is very slikery so it may have an effect over the long run. Parkerized would gunk up way too quickly, hard chrome would be a great option anodized would refer to aluminum and I’m not sure I want an aluminum gas tube. AP gas blocks are just about as good as anyone’s, I prefer split tube clamp ons as a rule because the set screw ones have a nasty tendency to unset and or negatively affect barrel harmonics if that is a concern to you.
