I was looking at gas tubes on Brownells' website and I came across a nitrided gas tube they offer. Does anyone have experience with these? I'll need a carbine gas tube for a Colt SOCOM barrel and I'm having a hard time coming up with a reason to spend $27 for a SS Colt gas tube when I can get a nitrided one for ~$6. I don't care about clone correctness or anything, just function.
