Recommend a 6mm ARC upper??

Who makes a good 6mm ARC upper?

The best part about ARs is building them. Uppers are easy, find a nice barrel and some associated parts and build exactly what you want, not settle for something someone else builds.

Build your own. I'm running a 22" Craddock Precision stainless match barrel on an Aero upper. I've been very pleased with it.

I built mine with a BCM upper and Eabco 24" and it is stupid accurate with factory 108 match ammo! Easiest one I've ever sighted in. Fun gun to shoot!
