Centurion Arms Barrels

[TMS951]

I have a 16” mid chf barrel. Bought in the last few years.

It’s reported to have a .80 gas port. It about shoots that way. I use a LMT enhanced bolt carrier, and Vltor A5-H4 with a spring co green spring.

I would not call it over gassed, it’s just gassed to make sure it always functions. That said it probably would always function with a .76 gas port as well.

They are shall we say strongly gassed.

Strongly gassed as in well-gassed?

They're some of the smallest ports in the industry.

My 14.5” mid runs tula with a carbine buffer, short strokes with h2 and standard spring.
Using wolf gold and 556 it runs very smooth with springco blue and h2. I dont notice significant gas-to-face when suppressed... id call it properly gassed for a do-it all barrel. Better than my bcm 11.5 in the gas department- without question.

I wish they offered more sensible profiles.

That it is not the case at this time. My 2019 production 12.5 carbine is ported at .066, and the last report I've seen of a .08 port on a 16" middy CA barrel is 2013. Most recent reports on 16" mids are smaller than BCM, or very near to .076 on the high end.

I just bought a new (2020) 16" mid-length. Gas port is .080

That's bullshit. To me, BCM's .076" is borderline gas hog as they shoot just like a 6920 to me.


Serious question:

Do you get any benefit from a mid gas if it's hogged out to run like a carbine?

[prepare]

16” barrels will have larger gas ports than the 11.5 - 12.5’ but .080 is too larger IMO

You are the only person I have ever encountered that considered a .80 gas port on a 16" mid to be 'small'

I'd like to see evidence of these new gasports.

Additionally Centurion does have a rep for 12.5" barrels with small (too small?) gas ports. To me all this means is they actually kind of suck at gas ports as there is no consistency in the gas drive of their barrels across the range. A company with gas ports figured out would have barrels that all deliver similar amounts of gas energy to the BCG regardless of barrel or gas system length.

I have one that shoots well. However, if you want a proper gas port, buy a Sionics reduced gas port or Extreme RGP barrel. I’m a fan. The RGP is more of a properly gassed barrel. It runs with or without gas port.
