Looking for a 6 ARC Barrel

[DackJaniels]

Hey everyone, I’m wanting to start a new 6 ARC project and need help either finding an off the shelf barrel that will work or going with a custom spun up barrel which is what I’m leaning towards.

So my requirements are:

Rifle Length Gas System
Longer than 16.5”


I’ll be using a URX 3.1 13.5, spikes tapered gas block and OCM5. I’m not wanting to go with a 16” barrel and using a crazy amount of shims to reach the proper length for the OCM5, so I’ll need something I can get cut to around 16.3-16.5”


I’m between a Craddock spun Bartlein or their RTR barrel (which I would’ve already ordered but the few things I’ve seen online are back and forth, and the general consensus is shoot it for 200 rounds to see how it shoots) but open to other suggestions! I was also looking at buying an X-Caliber blank and sending it off to have it turned if anyone has experience with that.

I don't have one, but Mos-Tek has the ability to make exactly what you're looking for.

centurion rifle length gas 18" https://centurionarms.com/6mm-arc-precision-stainless/18in-6mm-arc-barrel-rifle-length-gas/

they may still be running a sale for the 4th? Would try this over a proof, as far as off the shelf offerings go.

OCM5 is a 5.56 can not a 6mm can, I would suggest you re look the build unless you are planning on getting a baffle strike first round down the tube.
