I am looking for suggestions on a barrel.. I was waiting on the GM-m8 but its taking to long to get back in stock unless they have some huge discount on the stainless steel equal barrels.

Specs
16" or 18"
Mid length gas system
1:8 or 1:9 twist

Try Faxon Firearms, their barrels are very good.

MidwayUSA has the AR Stoner 416 barrels for $139.99 in either 16" or 18". Both are mid gas, .223 Wylde, 5R rifled, 1 in 8 twist, straight fluted. http://www.midwayusa.com/product/2228745849/ar-stoner-barrel-ar-15-223-remington-wylde-medium-contour-1-in-8-twist-fluted-stainless-steel

I back ordered a 16" and was going to use it on a build but forgot to cancel the back order when I instead chose an Odin Works 16.1" Intermediate Gas 416R barrel. I'll build a new upper for it eventually.

For my next build though, I'm eyeing the Faxon 20" Target barrel.

Thanks and I got a deal on a AR15.com barrels pretty cheap and the stoner would have been nice also too.

Do you mean an AR15 Performance barrel? If so, I have their 3 Gun barrel...excellent choice.

Don't forget you will need a receiver to mount it to.  .  I wonder how long before we
start seeing those back in stock?  But glad you found your barrel.  I'm waiting on a gas block
then my SHTF upper parts will be shipped to ADCO.
