Looks nice

Haven't ever used these long term before, but I like the black look to them. Wish I woulda seen them previously.

Great gas tube!
February 1, 2021
: KURTIS from Delaware, OH United States
The melonite gas tubes are awesome. They are a nice even black finish. The roll pins were easy to drive into my slim gas blocks. All the holes lined up perfectly. No fuss at all. Now I just need to hit up MAS for some barrels, can't wait to see how clean they look vs. the shiny stainless gas tubes on some of my other builds.

Tube arrived with corrosion
December 30, 2020
: Gary McConaghy from Chesapeake, VA United States
Had to clean up and treat a couple spots of corrosion/rust on the tube right out of the bag!
------------------------------------------------------------------------------------------------------------------------------------
MAS Defense Reply: Gary, the nitride process sometimes leaves a orange residue that can look like rust but is not. It should wipe right off. Regardless, you should not have received the gas tube in that condition. I apologize for the inconvenience.
Thank You for your business and your feedback!

Crazy fast shipping and quality product!
December 8, 2020
: from Texas
So of course, I waited until the most inopportune time to decide to do a build due to the current political climate. Nothing is available, all overpriced and backordered.
But MAS Defense came through for me. I wanted a very specific part and they had it at a great price and it was in my house in a matter of days.
They've made me a loyal customer, that's for sure!
