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.

I love mine. Good guys to work with.

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!

Going to make mine from my Smith and Wesson upper, after I bought one of their custom match ones. Just need a barrel and hand rail.

Faxon for a buget build. I had about a half a dozen of their barrels and all shoot .7 or better. And their CS is Excellent. I delt with them over something that ended up being my fault(upper barrel extension sleeve was out of spec)and they went above and beyond. CMMG, Sgt of Arms, JP, and Criterion make nice stuff. Criterion may only make barrels, idk. Build one with a Criterion barrel would be my suggestion.

Mine is a CMMG with a 20" barrel. Zero complaints and very accurate.

What kind of velocities are folks getting with their uppers they posted? I'm curious with this cartridge and the different barrel lengths.

2640 with factory 108 ELDMs and 2800 with hand loaded 90gr ELDXs over Varget.

On the Craddock website it looks like you're able to order a barrel and bcg and send them your upper and rail. For an additional $100 they'll assemble it. Some might find that appealing.

i don't see any 6ARC barrels on Criterion's web page. AFAIK, they're not in the 6ARC game, yet. I've been looking.

I'm getting about 2850 with a 90gr Sierra TGK and LeverEvolution out of the 22" barrel. It's a laser.
