In building a DPMS 308, would I use an AR15 gas tube of appropriate length?

Also, does the Bolt Carrier use an AR15 gas key?

Thanks!

I know they use the standard correct lenght gas tubes.  As far as the key, I would assume that is different than the AR15's.  Mine appears to be much bigger, but I could be wrong.

Thanks- any one know about the gas key?

The gas key diameter for the gas tube is the same, but the gas key dimensions itself is larger. The bolt, and carrier are larger than AR-15.
