New build with VLTOR A5 Kit...Go with ADJ or NA Gas Block?

[TommyTwoTone]

I'm building a 16" middy. This is my first time using the VLTOR A5 Kit and buffer tube. Could there be any benefits to using the A5 system with an adjustable gas block? Or does the A5 buffer work best with a non adjustable gas block?

Thanks in advance for the replies!

The A5 will function just fine without an adj. gas block. I don’t use adjustable GB’s on any of my builds any longer. When I did it was more about the rifle itself and what I was trying to do with the adjustable gas block, the gas port size of my barrel and the A5 really did not factor into whether I used one or not. My point of view as I’ve made on some other threads is that the adjustable GB introduce a potential failure point that a non-adjustable gas block doesn’t have. So I wouldn’t use one. Out of curiosity, do you happen to know the gas port size?

Whether or not an adjustable gas block will be useful has nothing to do with the buffer & spring. It's entirely dependant on gas port diameter. If the gas port diameter it's too large, an adjustable gas block will be useful. If the gas port is the right size or smaller, an adjustable gas block is as useless as teats on a boar hog.

The A5 is a great buffer system, but is not a replacement for proper gassing.

Do your research before buying the barrel.

Choose a 16" with the correct gas port and that will eliminate the need for an adjustable gas block.

Since you’ll need to buy a gas tube anyway, you can always go with one of Clint’s EZTune gas tubes as an alternative to an adjustable block.

Clint, is .076 the recommended custom tune gas port size for a 16" Wylde Mid? I have a lot of match grade .223 ammo to shoot but plan to shoot 5.56 too. All of it will be brass.

I should know tomorrow what the gas port size is.

Sound advice. Also, depending on the rifle's purpose, less adjustability may be a feature and not a bug.

Ports flow a little better, so 073 is the standard recommendation.

I'm not sure what you mean by 'ports flow a little better'. You mean non adjustable ports?

The specified gas port diameter on my Lothar Walther 16" mid is .076". If the actual turns out to be true to that number would you still recommend one of your inserts for only a 3 thousandth difference?

This right here.
