18" AR with rifle gas length

[becker_atc]

Got a stripped upper on the way and now looking at barrels. One I'm considering is criterion hybrid contour 18" with rifle gas length.

Any one use 18" with rifle gas? Any issues or special thing need be done to make it run?

Anyone shoot criterion AR barrels?

This will be my 1st Time where I assemble the upper

I would not expect any special considerations with that barrel/gas setup. What sort of receiver extension will you be using?

Most likely rifle style for fixed stock

That will be one smooth sob in my opinion.

If you were to select a carbine extension then I might suggest playing with the buffer weights some would help with recoil/BCG cycle speed.
While there should be zero issues with the carbine extension, If you decide to put a collapsible stock on it I would suggest a Vltor A5 system.

I have owned an 18" criterion 308 AR barrel. It would shoot to .75 moa or so. Plenty acceptable in my opinion, but I have had the best luck with my White Oak Armament barrel. They make an 18" in rifle gas as well. I wrote a review of it awhile back. See the 2nd link below if you are interested in a review.

My Stag 3G with an 18 inch barrel and rifle length gas system seems to work just fine. I haven't shot a lot of ARs so I really can't give a comparison.

I, like ASP, have used a white oak armament 18" barrel with rifle length gas. It was the most accurate AR I have ever owned and I regret ever getting rid of it. WOA will also include a matching bolt for $50 more if you want.

I've only run intermediate gas on an 18" (Noveske) with the Vltor A5 RE & buffer, but it was smooth as a baby's butt and more accurate than me!

I've got two Black Hole Weaponry 18" barreled AR's with rifle length gas systems. Love em.
