I need a gas tube for my 7.5" PDW build. I've seen 6.625 and 6.75. Nitromet, Melonited and stainless
Options: Prices include shipping: No-name stainless: $12 Spikes Melonited: $20 Nitromet: $18 Nitromet Carburizing QPQ: $19 Can't find a Noveske anywhere. Any other suggestions? |

Yes. Excellent. Not all are created equal. Melonite > Untreated Stainless. http://www.ar15.com/forums/t_2_282/218226_Where_are_all_the_melonite_gas_tubes_.html From Tom: They withstand heat a lot better than an un-treated gas tube. We stopped melting gas tubes and began breaking gas blocks in half instead. They also do a better job fighting Corossion. And they are non-reflective.
Also standard gas tubes are 304 stainless, same with the Melonite ones. |

If it's not cryo-treated and hard-chrome lined, you might as well use a silly straw.

It's not rocket surgery if you're going to run a 7.5" barrel look into a pig tail gas tube especially if you're going to have a can.

V7 makes one out of inconel, I'd imagine that if you've gotta have the baddest gas tube in the land, that would be the place to go.

I'm thinking about hitting my gas tube with some heat resistant black spray paint when I do my barrel swap, just to cut down on the shinyness.

The Mennonite tubes also look better under free float rails with lots of holes.

I like the melonited gas tubes for just the sole purpose that they're lower observable than the normal ones. But other than that, no advantage between either.

View Quote I chose the Spikes melonite because it's black mostly. There was a painted stainless, but the finish looked better on the melonite and it was less than $6 more. What the hell, why not? |

I did a 100rd beta dump on a buddies post sample with one of my uppers. Awhile later I had some corrosion issues with the gas tube. Now I prefer melonited gas tubes - just in case I feel like performing a beta dump on full auto
It will never make a difference unless your shooting full auto rates for multiple magazines. If you really want to go all out you can buy an inconel tube from V7. I'd love to see one of those ran until it fails. FWIW I've got two pistol gas uppers and I just use a standard pistol gas tube. I wouldn't spend the money on a pigtail tube unless it already had issues and I thought it might help.

No difference 99% of the time. I've shot a decent bit of F/A without any issues. No clue who made my gas tubes. For a semi? You aren't going to hurt it no matter what you're using.

I don't think the gas tube is making the gas block fail sooner, only lasting so much longer that the gas block is the first to go. View Quote View All Quotes View All Quotes Quoted:

That's his point. He'd rather have the fail point (the point with less resistance to heat) be the cheap and easy-to-replace gas tube than the gas block. And I agree. |

That makes no sense. Why would you want your rifle to fail sooner? Unless of course you're out there in the field with everything you need to change out a failed gas tube. View Quote View All Quotes View All Quotes Quoted:

That's his point. He'd rather have the fail point (the point with less resistance to heat) be the cheap and easy-to-replace gas tube than the gas block. And I agree. There's are videos out there of torture tests, the guns usually go through 600-1000 rounds on full auto without a chance to cool for several minutes before the gas tube melts and the auto reciprocating feature is disabled. You have to really try and make the gas tube melt, so they're saying if they're going to be torturing their rifle like that, they'd rather have the $7 part fail a few seconds before the gas block cracks open, which is a more difficult fix (pins might get jammed if the thing wrenches open or expands itself to death) and a harder part to find. Someone using an m-16/m4 to the extent it would require to fail in this manner in the field, would be in a huge amount of trouble, so for that guy, maybe invest in a melonite tube. For everyone else, it's just mall ninja style |
