6mm ARC

[Gtscotty]

Yes it needs the + gas system. My 224 Grendel does not have the+ gas, and with gas tuned way down and rifle weight buffer it is still hard on brass.

Yeah, I have a mid-length .308 that I think would probably benefit from the higher dwell time of an intermediate or rifle length gas system. I'm definitely going long on the ARC, no reason not to.

That's cool but I'm still going to test and see if normal gas lengths will work. If I do get one it will be a 12 inch.

Cool, let us know how it works out.
