I asked in another thread (http://www.calguns.net/calgunforum/showthread.php?t=228376) about a Krieger 16" barrel (http://www.blackweaponsarmory.com/magento/index.php/bwa-ar15-featured-products/krieger-ar-15-cut-rifled-custom-match-barrel.html). The general consensus was to pass, because it was a carbine-length gas system.

Now, I'd like ask your impressions of a White Oak Armament barrel: midlength gas, stainless steel match grade, Wylde chambered with M4 extensions.

Assuming the WOA in the midlength configuration is decent, which should I get: the 16" (http://www.rainierarms.com/?page=shop/detail&product_id=600), or the 18" (http://www.rainierarms.com/?page=shop/detail&product_id=449)?

IN 2005 I picked up a new 16" Midlength SS match, .223 Wylde w/ M4 extensions. Put it together with an off the shelf CMT upper and BCG.

Shoots 1 MOA or less consistently with 69 gr Sierra Match King.

For 18+" barrels, go for a rifle length gas system.
For 14.5+" barrels, go for a midlength gas system.

I have a JP rifle length gas system on an 18" upper and love it. Adjustable gas block makes it even softer shooting. I would go for an 18 just for the practicality of it without losing much on the shorter 16" version.

Would anyone else like to weigh in? I don't know enough yet to make an informed decision.

18" with the minimum of 1/8 twist rate.

You save only 2" from the shorter barrel, but you lose the important 2" worth of velocity of the 223/5.56 round.

White Oak is really good stuff. If you are thinking you need a gun that handles very quickly, get the 16 with a mid-length. If you want a general purpose gun that handles almost as quickly as the 16, get the 18. If I had just one, I'd get the DMR 18". If I had 2, one of them would be the 18.

all the best,
Mike

Buddy has a 18" heavy fluted WOA upper. Its slick and shots very well (sub MOA with 69gr SMK). The odd thing is it feels very rough when you charge it like there is sand in rifle yet it been completely reliable. If you ride the charging handle it locks up just trying to strip a round from the mag. He has shot about 2K round through it and it still feels like the BCG is grinding on something the whole way yet there is no sign of ware on the BCG or receiver. We just gave up and shoot the damn thing.

Like I mentioned in your other thread. I have a 16" Shilen blank that was finished by WOA, and I am more than happy with it. Guaranteed sub-MOA too.

Why? Whats wrong with a carbine length system? My RRA 16" carbine upper has been flawless.

Nothing wrong with a carbine gas system. It's just that a midlength and rifle-length are more reliable.

Mid-length is more reliable and softer shooting.

EDIT: Id also like to note that I have a carbine version too without problems, and I am fully satisfied with it.

nothing wrong with Carbine but on a 18" its either mid or rifle length but to be honest to OP depending what you are plan on doing with this upper determines the choice of barrel length and gas system.

If you the best proformance out of your upper that will give you the best accuracy at a longer distances 18" hands down and go midlength IMO
